Tomato – Black Cherry

black-cherry-tomato-webBlack Cherry is an indeterminate tomato variety, with fruits that are about the size of ping pong balls.  I last grew this variety 3 summers ago, and the tomatoes were delicious.  I will be growing this plant outside in a 32 gallon bucket, and I will definitely need to watch the fluid level and add more as needed.  I expect this plant will get huge (6-8 feet tall) and will consume more than 60 gallons of fluid over the course of the season.

Mar 17 = Day 0.  Plant started from seed (Baker Creek).  Seeds (3) sowed into one 1.5 inch rockwool cube in 2 inch net-pot.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Mar 21 = Day 4.  The seeds have germinated, and are placed directly under a fluorescent light (spiral bulb, 23W, 6500k) for 18 hours per day.  The bulb is positioned 3-4 inches above the plants.

Mar 24 = Day 7

Mar 28 = Day 11.  Plant is now being put into a sunny window for 3 hours per day, then back under the fluorescent light for an additional 15 hours.

Mar 31 = Day 14.  Plant transferred to a small plastic jar containing 3 cups of Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.

Jul 28 = Day 134.  The foliage looks terrible, but the plant continues to provide lots of ripe tomatoes.

Jul 31 = Day 137.  Harvested 102 tomatoes.  Total = 683.

Aug 3 = Day 140.  Harvested 29 tomatoes.  GRAND TOTAL = 712.

At this point, many tomatoes are cracking on the vine, and the plant foliage is mostly dead.  Plant was taken down at this point.  This plant started with 32 gallons of fluid, and I added 54 gallons during the season.  There was still 11.5 gallons left when I took the plant down.  Total fluid used =  74.5 gallons.

Swiss Chard – Flamingo Pink

swiss-chard-flamingo-pink-dsc02548Swiss chard is one of my favorite greens.  I steam the stalks and leaves and then coat them with a dressing of olive oil, garlic and black pepper.  By only harvesting the outer leaves and allowing the inner leaves to keep growing, these plants can provide numerous harvests.  I have been growing El Dorado yellow Swiss chard for several months, but the plants are starting to get old, so now I am starting these Flamingo Pink plants.  Hopefully I can get some decent harvests from these plants before my indoor grow room gets too hot in the summer.

Mar 17 = Day 0.  Plants started from seed (Baker Creek).  Seeds sowed in 1.5-inch rockwool cubes in 2-inch net-pot.  Used 2 rockwool cubes, with 2-3 seeds per cube.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Mar 21 = Day 4.  The seeds have germinated, and were placed directly under a fluorescent light (spiral bulb, 23W, 6500k) for 18 hours per day.  The bulb is positioned 3-4 inches above the plants.

Mar 24 = Day 7

Mar 28 = Day 11.  Plants are now being put into a sunny window for 3 hours per day, then back under the fluorescent light for an additional 15 hours.

Mar 31 = Day 14.  Plants transferred to small plastic jars containing 3 cups of Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.

IMG_20170331_140252920 (1)
Mar 31 = Day 14

Apr 7 = Day 21.  Installed the plants into two 5 gallon buckets using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.  Plants will continue to grow indoors, placed in front of a sunny window where they will receive 4 hours of direct sunlight per day.

Jun 6 = Day 81.  Plant on the left has a bit of white fuzzy fungus on its roots.

Jun 6 = Day 81.  The leaves of the plant on the left are turning brown, possibly due to a fungal infection on the roots.  Before the leaf quality can deteriorate any further, the entire plant was harvested at this time.

Jun 19 = Day 94.  Added 0.75 gallons Regular-Strength Blend to the remaining bucket.

Jul 6 = Day 111.  Added 2 gallons Regular-Strength Blend.

Jul 12 = Day 117.  Harvested entire plant.  Total fluid used by this plant = 6.5 gallons.

Marijuana – Northern Lights

I will be growing a Cannabis indica strain called ‘Northern Lights’.  The type I will be using has been hybridized with an autoflowering strain, meaning that the plant will flower on its own schedule, independent of photoperiod length.  It is also feminized, meaning that the plant will be female and will therefore produce the desired flower buds.  These seeds are expensive, so in order to maximize the size of the harvest from each seed, the growing conditions will be a bit more complicated than my usual simple Kratky buckets.  I will be using a growing method commonly referred to as Deep Water Culture (DWC), using a separate reservoir bucket.  Here is the setup:

  • Connect two 5 gallon buckets together using PVC tubing and fittings as described here: Two Bucket System.
  • Use a water pump (PonicsPump PP09205, 92 gallons/hour) to circulate the fluid between the two buckets.
  • Use an air pump (Whisper Model 10, 0.5 L/min) and an air stone to elevate the oxygen levels in the fluid.
  • The main source of lighting will be a 200-Watt LED grow light.
  • Use frozen jugs of ice to lower the temperature of the fluid to the desired level (64-68 °F, 18-20 °C).  Frozen jugs will need to be replaced every 24 hours.
  • Wrap the buckets in towels to provide some temperature insulation, and put the whole assembly inside of a 27-gallon storage tote, to contain the fluid in case of leaks.

Nov 27 = Day 0.  Plant started from seed (Blimburn Seeds, sourced from SeedSupreme).  Seed sowed in 1.5-inch rockwool cube in 2-inch net-pot.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Nov 29 = Day 2.  The seed has germinated.  I can see the taproot emerging from the seed, but the leaves have not yet emerged.  Nonetheless, I have placed the plant directly under a fluorescent light (spiral bulb, 23W, 6500k) for 18 hours per day.  The bulb is positioned 3-4 inches above the plant.  The bulb generates a lot of heat, so I placed a small fan about 3-4 feet away from the plant to blow air on it during the day.  I also placed the plant on top of a heating pad (set on ‘low’), which cycles on/off every 30 minutes during the night to keep the plant warm.

Dec 1 = Day 4
img_20161202_134945271-1
Dec 2 = Day 5

Dec 7 = Day 10.  Plant is about 1-inch tall, and the main root is about 4-inches long with many branches.  To ensure that the root system has enough room, the plant was moved into a slightly larger 3-cup container containing the same nutrient solution as above.

img_20161207_155546764-1
Dec 7 = Day 10

Dec 10 = Day 13.  To acclimate the plant to a higher concentration of nutrients, the solution was changed to the following half-strength solution (per gallon of tap water): 1 g Masterblend 4-18-38, 1 g calcium nitrate, 0.5 g magnesium sulfate, 0.1 mL Dyna-Gro Pro-TeKt, 1.3 mL pH Down.  pH = 6.0.  N-P-K (in ppm): 51-47-101.

img_20161213_105241161-1
Dec 13 = Day 16.  The first set of real leaves is turning yellowish, but the rest of the plant is green.

Dec 13 = Day 16.  Plant transferred to the Two Bucket System.  The system contains a total of 9 gallons of fluid, which results in having the fluid level just at the bottom of the net-pot in the plant bucket.  For nutrients, the Regular-Strength Blend was prepared.  N-P-K (in ppm): 103-95-202.

For lighting, a 200-Watt LED grow light was positioned 18-inches above the plant, running 18 hours per day.  A fan also blows on the plant during the hours that the light is on.

Going forward, daily maintenance of the system is conducted as follows:

pH
If the pH is below 5.0 or above 6.5, the pH is brought back into the range of 5.5-6.0 by the addition of either pH Up or pH Down.

Temperature
If the temperature of the fluid rises above 68 °F (20 °C), then a sealed jug of ice is added to the reservoir bucket.  The ice cools the system down to its lowest point in 2-3 hours, and then the temperature slowly returns to the starting point after 18-24 hours.  I add enough ice to bring the temperature minimum down to about 60-65 °F.  To determine how much ice to add, I use the following guide:

Reservoir Volume Ice Volume Cooling Achieved
9 gallons 1/2 gallon 7 °F
9 gallons 1/4 gallon 3.5 °F
6 gallons 1/2 gallon 10 °F
6 gallons 1/4 gallon 5 °F

A spreadsheet containing all of the daily measurements of temperature and pH can be found here: Temperature and pH Measurements.

Mar 6 = Day 99.  Plant is starting to flower.  This plant is female, as evidenced by the white strings (pistils).

Mar 6 = Day 99.  The fluid in the buckets was entirely replaced.  All remaining fluid (4 gallons) was removed from the system.  6 gallons of new fluid (Bloom Blend) was added.  N-P-K (in ppm): 74-114-243.  The Bloom Blend has a lower N content than previous blends, to discourage vegetative growth and encourage flowering.

Mar 20 = Day 113.  The fluid in the buckets was entirely replaced.  All remaining fluid (3.5 gallons) was removed from the system.  6 gallons of new fluid (Bloom Blend) was added.  N-P-K (in ppm): 74-114-243.

Mar 31 = Day 124.  The fluid in the buckets was entirely replaced.  All remaining fluid (4 gallons) was removed from the system.  6 gallons of new fluid (Bloom Blend) was added.  N-P-K (in ppm): 74-114-243.

Jun 5 = Day 190
IMG_20170605_132732704 (1)
Jun 5 = Day 190.  The terminal bud (cola).

Jun 5 = Day 190.  Many of the fan leaves are yellowing, especially near the terminal bud.  Upon inspection of the trichomes with a 30x magnifying glass, there are a few trichomes that are turning amber, but most appear to be clear or cloudy.  Almost all of the pistils on the plant have turned brown.  I think the time has come to harvest this plant, since I do not want the cannabinoid quality to deteriorate.  It has now been 13 weeks since this plant started to flower.

For the final step of the growing process, I will be performing a “flush”, which involves removing all nutrient fluid from the system and replacing with plain water (adjusted to pH 6).  This can help to clear out any accumulated nutrients, resulting in a cleaner burning, better tasting final product.  For the DWC system I am running, the flush only needs to occur for 1-2 days.

All remaining nutrient fluid (3 gallons) was removed from the system.  5 gallons of plain water (pH = 6.0) was then added.

Jun 7 = Day 192.  After 2 days of flushing, the plant was harvested.  All fan leaves were removed.  The remaining stems (covered with trichome-laden buds and sugar leaves) were hung upside to dry.  A small fan was used to keep the air moving around the drying pieces, but was not pointed directly at them.

IMG_20170607_181742585 (1)
Jun 7 = Day 192

After 5-6 days, the buds and leaves were mostly dry, so they were carefully trimmed off the stems and placed into a glass dish.  The dried buds were allowed to sit in the open for another day, and were then transferred into glass quart jars.  For a few weeks, the jars will be opened daily to allow air exchange.

IMG_20170614_141026896 (1)
The final product.

Overall, the marijuana plant consumed and transpired 26.5 gallons of nutrient fluid.  In the future, it might be more convenient to grow the plant in a much larger vessel (such as a 32-gallon trash container) rather than the smaller Two Bucket System that I used here.

Ideally, the temperature of the fluid would have been kept within the range of 65-68 °F for the entire growing period.  I did my best to control the fluid temperature by adding jugs of frozen ice everyday.  During the winter months, it was easy to keep the temperature in the desired range, but as the spring came, the grow room got warmer, and the temperature cycled out of the desired range on a daily basis:

Arugula – Roquette

arugula

Arugula is a tasty green, but it can be a bit overpowering if used alone. I like to include about 50% arugula in my mixed green salads.

Oct 9 = Day 0.  Plants started from seed (Botanical Interests).  Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Oct 11 = Day 2.  Plants germinated, placed directly under a fluorescent light (spiral bulb, 23W, 6500k) for 16 hours per day.

img_20161018_125822118-1
Oct 18 = Day 9.  2 seedlings per rockwool cube.

Oct 18 = Day 9.  Installed the plants into two 5-gallon buckets using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.  Plants now receive 10 hours of light per day from the LED grow light.  Additionally, one of the buckets is getting aeration from a small air stone connected to the GH2716 air pump.  The other bucket is non-aerated.

Nov 18 = Day 40.  Aerated bucket is on the right.

Nov 18 = Day 40.  Plants were placed in front of a window receiving about 3 hours of sunlight per day.  The use of the LED grow light was discontinued.  The pH of the fluid in the buckets was measured: non-aerated = 4.5, aerated = 5.0.  Since this is a bit on the low side for optimal plant growth, the pH was raised up to 6.0 by the addition of ‘pH Up’.  The non-aerated bucket received 5 mL of pH Up diluted in 1 cup tap water.  In the aerated bucket, the fluid level was slightly lower, so this bucket received 4 mL pH Up diluted in 5 cups tap water.

Nov 27 = Day 49.  Use of aeration was discontinued at this time.  The plants appear to be the same size, so aeration does not offer any benefit to the growth rate of the plants.

Mar 13 = Day 155

Mar 13 = Day 155.  One of the plants in the right bucket is bolting.  The other plants are still growing well.  The left bucket has plenty of fluid, but the right bucket is getting light, so I added 1 gallon of Regular-Strength Blend.

Mar 31 = Day 173.  Added 1 gallon of Regular-Strength Blend to each bucket.

IMG_20170414_095012267 (1)
Apr 14 = Day 187

Apr 14 = Day 187.  Added 1 gallon of Regular-Strength Blend to each bucket.  Plants are bolting, so I trimmed off the flower stalks.

Apr 19 = Day 192.  Since the plants have bolted, the leaves have gotten quite bitter, and so the plants were discarded at this time.

Total fluid used = 6-7 gallons per bucket.

Swiss Chard – El Dorado

Alf Christianson Seed Co.After a long and hot summer, my indoor grow room is just about empty, so I have lots of room to start up a large batch of new plants.  For a while, I have been wanting to do an experiment to determine whether aerating the fluid in the buckets would be beneficial for plant growth.  My general approach with Bucket Hydroponics has been to ‘Keep It Simple’, but I am curious about whether aeration would provide a significant benefit.

In this experiment, I will be growing El Dorado Swiss Chard.  Half of the plants will receive aeration, and the plants will be grown in 5 gallon buckets.  I will sow enough seeds for 15 plants, and I will pick out the best plants for the experiment.

415y2bj80bol-_sx300_For aeration, I will be using the General Hydroponics Dual Diaphragm air pump, model GH2716.  I bought this pump used from my local hydroponics store for $40, so my investment is not large.  This pump is a bit noisy for using inside my house, so I will have to see some real benefits to justify its use.

Sep 25 = Day 0.  15 plants started from seed (Park Seed). Seeds sowed in 1.5 inch rockwool cube in 2 inch net-pot.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Sep 27 = Day 2.  4 of 15 plants have germinated.  Placed seedlings directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.

Sep 28 = Day 3.  8 of 15 plants have now germinated.

Sep 30 = Day 5.  12 of 15 plants have now germinated, but 4 of the plants are growing too leggy and are falling over, or have a bit of mold on the stems.  These 4 plants were discarded.  The remaining plants were put into a sunny window with a small fan blowing on them for 3 hours per day, in an attempt to toughen up these plants.  The rest of the day, the plants are under the fluorescent lights.

Oct 5 = Day 10.  Plants are still getting too leggy, so they were moved directly under an LED grow light for 11 hours per day, with a fan blowing on them.

Oct 8 = Day 13.  Installed the plants into 5 gallon buckets using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.  Plants continue to receive 11 hours of light per day from the LED grow light.  Additionally, 3 of the buckets are getting aeration from small air stones connected to the GH2716 air pump.  The other 2 buckets are non-aerated.  In some of the buckets, more than one plant is growing in the rockwool cube; I am planning to thin down to 1 plant per bucket eventually.

Oct 10 = Day 15.  The plants receiving aeration are circled red.

Oct 19 = Day 24.  The plants are growing, but they tend to flop over and have difficulty standing upright.  The grow room is still too hot at this time of the year, fluctuating daily between 75-80 °F.  Checking the quality of the solutions, the aerated fluid is crystal clear, while the non-aerated fluid seems cloudy and turbid.

Nov 13 = Day 50.  The 3 aerated buckets are on the right.

Nov 13 = Day 50.  The plants are getting larger, and they were starting to flop over, so I installed rigid collars to keep the plants upright.  The best collars are shown on the left, consisting of 4 inch ABS couplings.  The ABS collars are heavy and stable.  Other collars were made of cardboard, but these did not work quite as well as the ABS couplings.  I placed the ABS collars on the 2 largest plants, the ones in the non-aerated buckets.

Nov 18 = Day 55.  Aerated plants are on the right.

Nov 18 = Day 55.  The plants without aeration are clearly bigger than the plants in the aerated buckets.  The experiment was concluded at this time.  The result of this study is surprising, I had expected that aeration would provide some benefits to the plant growth, but it did not.  Perhaps the aeration resulted in turbulence to the roots in the bucket, which was inhibitory to growth.  On a positive note, the fluid in the aerated buckets was very clear and clean.  In contrast, the fluid in the non-aerated buckets is slightly cloudy, and the stagnant fluid has a ‘skin’ on the top with lots of precipitates at the bottom of the bucket.  Movement of the fluid within the bucket is helpful for keeping the fluid fresh and clean, but is not necessary for healthy plants.

The 3 plants in the aerated buckets were harvested.  The pH of the fluid in the buckets was measured: 4.5, 5.0, 6.5.  I’m not sure why these buckets had different pH values.

The 2 plants in the non-aerated buckets were allowed to continue growing.  These plants were placed in front of a window receiving about 3 hours of sunlight per day.  The use of the LED grow light was discontinued.  The pH of the fluid in the buckets was measured: both buckets read 4.5.  Since this is a bit on the low side for optimal plant growth, the pH was raised up to 6.0 by the addition of 5 mL of pH Up diluted in 1 cup of tap water.

Sep 4 = Day 345

Sep 4 = Day 345.  After almost a year of growing, I am finally going to harvest the remaining leaves.  I find that the stalks are a bit fibrous and inedible, but the leaves are still OK for steaming.  Each bucket has about 0.5 gallon of fluid remaining.

Total fluid consumed: 17 gallons (left plant), 13.75 gallons (right plant).

Eggplant – Rosita

801d43a7bc394a3385df14ce6305a85c1Rosita is an heirloom variety of eggplant, originally developed in 1940s by the Puerto Rico Agriculture Experiment Station in Rio Piedras.  The plant yields lavender-pink fruits that are about 8 inches long and 4 inches wide, with a mild, white inner flesh.

Jun 18 = Day 0.  Plant started from seed (Baker Creek).  Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot. Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Jun 22 = Day 4.  Plant germinated, placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.

Jul 1 = Day 13.  Installed plant into 11 cup plastic container using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.

Aug 11 = Day 54

Aug 11 = Day 54.  Mites have been found on several areas of the plant, near the newly growing shoots.  Forcefully blasted the mites off by spraying with diluted horticultural oil (diluted 1 tbsp into 1 quart of water in a spray bottle).

Aug 13 = Day 56.  Inchworms (loopers) were found on several of the leaves, creating small holes.  Entire plant was sprayed with a solution of BT, diluted in water (5 mL BT per liter).

Sep 12 = Day 86.  Plant has grown quite large, but still has no pollinated fruits.  Several flowers are present, and I have been hand pollinating, but still no success.  Also, most of the plant’s leaves are infested with mites.  There does still seem to be plenty of fluid left in the reservoir though, so I guess I’ll keep it around for a bit longer.

Sep 12 = Day 86.  This plant has beautiful flowers, but no fruits.

Sep 22 = Day 96.  Plant leaves look bad, with lots of mites and inchworms, plus some damage from powdery mildew.  Plant is still not producing any fruits, so the plant was discarded at this time.

Total fluid used = 24 gallons.  Final pH of fluid = 6.5.

Lettuce – Lolla Rossa

lollaLolla Rossa is a frilly, loose-leaf green/red lettuce variety.

Jun 18 = Day 0.  Plants started from seed (Botanical Interests).  Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot. Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

Jun 22 = Day 4.  The plant has germinated, and was placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.

Jul 1 = Day 13.  Installed plant into 3.5-gallon buckets using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.  Plant moved to indoor grow room, receiving 9 hours LED grow light per day.

Aug 11 = Day 54.  The front side of the plant (left) gets direct sunlight, and the leaves have turned reddish.  The back of the plant (right) gets light mostly from the LED grow bulb, and these leaves are more greenish.

Aug 12 = Day 55.  Began harvesting lower leaves for use in salads.  Plant is getting too tall and top-heavy, so it was tied to a pole to keep it upright.  Also, grow room is very hot (above 80 °F during the day), so the use of the LED grow light was discontinued.  Plant is now receiving 3-4 hours of direct sunlight per day.

Sep 2 = Day 76.  All lower leaves have been harvested, and the plant has bolted, so the remaining upper leaves taste bitter.  This plant has grown to be almost 4 feet tall!  Plant was discarded at this time.  Total fluid used = 2.8 gallons.  Final pH = 5.0.
