-
- Introduction:
- These are plans to make a fairly portable, and very inexpensive
- water culture (advanced hydroponic) system. These plans only
- explain how to make the garden itself, and do _not_ explain how
- to use/maintain it. If you plan on using this garden, you should
- get yourself a good book on hydroponics, and look it over
- (especially the parts about what nutrient solutions to use, your
- garden vareity Miracle-Gro won't do the trick).
-
- Disclaimer:
- I am intentionally leaving out those parts about plant
- nutrition, light cycles, etc. so as not to appear to be writing
- a guidebook for growing marijuana. It is also to make you seek
- out _another_ source of information so your knowlege of
- hydroponics comes from more than just this file. I do not grow
- marijuana, and never have. I'm just a high-tech home gardener
- with information to share. If you are caught growing marijuana
- while using the system described herein, don't even think of
- running to me, I didn't tell you to grow marijuana. In fact,
- I'd suggest planting a crop of cherry tomatoes, which can be
- fooled into producing fruit indoors year round, and is a very
- easy plant to start hydroponics with.
-

-
- Materials:
-
- 1 5-10 gallon bucket
- 2 Pieces of PVC or ABS pipe, 8-10" long, 5" or greater diameter.
- 4 Caps for PVC/APS pipe ends.
- 1 waterpump capable of about 50 Gallons Per Hour (you will need
- a bigger pump if you choose to make this a larger system)
- 4' of hose that will fit the waterpump (often 3/8")
- 1 TEE joint (or Y-splitter) that fits the water hose
- 4 clamps for the water hose (one for pump to hose, and 3 for
- hoses to TEE fitting.)
- 1 Airpump, airstone, and some airline from a fish tank.
- 1 Can White epoxy based spray paint
- 1 Can Black Epoxy based spray paint
-
- 1. Everything must be made light tight. Paint all hoses, the
- bucket, the PVC/ABS (which will be called PVC from now on)
- and the lid of the bucket with a layer of black paint. Let
- it dry overnight, and then cover it with a layer of white
- paint (to make it reflective, and reduce the temperature of
- the nutrient solution).
-
- 2. Take each of PVC pieces and drill a 1" hole in the side,
- about one inch from the end. Then epoxy the caps onto the
- ends of the PVC.
-
- 3. Drill the inlet/outlet holes (these should be located on the
- caps of the PVC), See diagram
- +------ 1" hole
- V here
- ------------------------------ ----
- Outlet ---> | |
- hole | |
- | |
- | | <-- inlet
- ------------------------------------ hole
-
- The inlet hole should be as low as possible (as close to the
- wall of the PVC), and the outlet hole should be as high as
- possible)
-
- 4. Now cut two 5" holes in the sides of the bucket (close to the
- top), and epoxy the PVC in place, so about 2" of pipe (and
- the outlet hole) are inside the bucket, and the 1" hole is
- facing straight up.

- 5. Place the airstone in the bottom of the bucket, and find a
- place for the airpump. If you are planning an indoor garden,
- with enriched CO2 in the air, then the pump should be OUTSIDE
- of your enclosure. The idea of the pump is to dissolve
- oxygen into the nutrient solution, and not to dissolve CO2.
- CO2 can kill rootsystems. If you are growing outside, or not
- enriching CO2, then the pump can sit anywhere.
-
- 6. Place the waterpump in the bottom of the bucket (assuming it
- is a submersible one) and attach a hose to it. long enough to
- reach the top of the bucket. Cut a hole in the lid of the
- bucket for this hose to go through. Then attach the TEE
- fitting to the hose. Now attach hoses to the free ends of
- the TEE, and run them to the inlet holes on the end of the
- PVC pipes. Use clamps on the TEE fitting and on the pump
- itself, but use epoxy to attach the hoses to the PVC. This
- seal must be completely water tight. Let them dry for 24
- hours.
-
- 7. Put some water in the bucket and turn on the pump. What
- should happen is the PVC pieces will fill with water, and
- then when they are full, they should begin to continuously
- drain out the outlet holes, and back into the bucket. If you
- are getting leaks anywhere, fix them immedately. If water is
- coming out of the 1" hole on the top of the pipe, then either
- your pump is too strong, or your outlet hole is too small.
- Fix one or the other.
-
- 8. Empty the system (hint, remove the hose from the pump to
- drain the arms), and replace the water with some form of
- hydroponic nutrient solution (look in a hydroponics book for
- details on what exactly to use, or visit a gardening store,
- and ask)
-
- 9. Place your plants into the system. The best way I have
- found to do this is to take a 1 1/8" garden hose and cut a
- 1" tube off of one end. Then slit the tube down one side.
- Wrap the stem of your plant (just above the roots) with
- polyester fluff (available at aquarium stores, for stuffing
- into external water filters) and then wrap the garden hose
- around the fluff. Then force the hose into the hole at the
- top of the PVC arm. People also have used rubber stoppers.
-
- 10. Turn on the air/water pumps, and let your garden grow.
-
- Comments:
- This is obviously just a small setup, but these plans can
- easily be modified for much larger systems, using longer pieces
- of PVC, or more than one pair of arms, and a larger bucket to
- hold the nutrients (I've seen one made with a 55 gallon drum,
- and 8 seperate arms, each holding 4 plants)
-
- I personally use this setup indoors (under a skylight in my
- apartment) to grow 2 cherry tomato plants. What you do with
- your own garden is your own business, and Obviously I can't be
- held responsible if you choose to grow anything illegal.
-
- Starting Seeds:
-
- This system is not for seeds. Either purchase small plants, or
- start your seeds in a pan of vermiculite, flooded with 1/2
- strength hydroponic nutrient fluid. When they are about 4-6
- inches tall, they are ready to be moved to the system. Remove
- them gently from the vermiculite, using clean water to get
- every last chunk off of the roots. Then wrap the stems in
- polyester fluff and garden hose (see above)
