I recently designed a flowering bed following blueprints by Soma of Soma Seed co. After a few grows using this new bed style of planting, I've decided to make some modifications and design a smaller version of this great idea.
First I'll show you the larger design I built following Somas' grow book, "Organic Marijuana, Soma Style" Recommended read for organic growers.Then a step by step of my newest attempt.
1. 10-15 gallon plastic nursery pot w/drain holes.
2. Root Felt material..
3. Plastic coated chicken wire..
4. 2-3" PVC..
5. Hydroton lava rocks..
6. 2 1/2" flathead screws..
7. Screw gun, drill bit..
8. Medium of choice.
1ST: I always clean everything involved, usually with soap and water, then spritz with a light bleach solution and rinse. Inspect plastic planter, sometimes drain holes are not cutout properly and need a few more added.
2ND: Cutout a piece of felt slightly larger then bottom and install, this will keep the hydroton rocks from falling thru the large drain holes repeatedly.
3RD: Install root blocking felt and Hydroton rocks on top.
4TH: Install 2 PVC air tubes opposite one another. You want the base pushed just a 1/4" into the hydroton rocks. Secure at top with 1/2" screws. Drilling a pilot hole makes this much easier.
5TH: Cut to fit and install plastic coated chicken wire directly on top of the hydroton rocks. Be sure to fit tightly around base of PVC tubes.
6TH: Install a 2nd piece of root blocking felt on top of the chicken wire again cutting it as close as possible. Use the PVC tubes to mark out the cutouts before hand assures of a proper fit.
7TH: I now install 2inches of Coirbrick-(Coconut Husk) spread it out carefully so as not to move the root felt.
8TH: Fill to within 2" of rim with your favorite Organic medium.
Suggestion Organic growing you really feed the medium and not so much the plant. Begin using foods with Mycorrhizae Inoculants and bio accelerators a week prior to planting to establish a happy productive medium. (Foxfarms' Ocean Forrest soil contains this)
