Heya- put one together for AFOAF last week

You'll need-
Pump 15
Poly tube 1/2" 20ish
Poly tube 1/4" 10ish
1/2 gph drip emitters .50 per plant
Timer (digital) 20
Resivior(whatever you have) 10
Barbed 1/4" tees(1per 2 plants).35 ea.

Make a manifold from 1/2" tube(you'll have to block 1 end). Insert tees to match plant setup. Run 1/4" tube to each pot, and attach dripper. Mount pump to manifold. Place pump in res, fill w/ nute solution of choice. Set timer to turn on pump for, say, 5 min (1/24th gallon)per hour lights on- no water when lights off. You can adjust watering cycle by adjusting timer on/off intervals.

System assumes that you can drain to waste.
System assumes that your media will drain well enough to allow good leach-thru- coco, cocoperl, RW in a proper tray, Promix/perlite 50/50%.
I like at least 10% run-thru in drip.
Top off res w/ fullstrength nute as needed. Check and adjust pH at each top-off.

You can skip the emitters, but they make water delivery MUCH more consistant- I'd go the $.50 cents.

You can get all of this at any good hydro shop, or Home DePot, Agway, etc- I like the Raindrop brand stuff. Res can be anything that'll hold water- Pickle barrels are the bomb, but you gotta CLEAN them or ph'll be funky and your room will reek of pickles. No metal drums.

Hope this helps
rhizome Reviewed by rhizome on . Watering systems I'm trying to make a timed, measured watering system, to better regulate my grow. I don't have the money for a commercial drip system. Does anyone know how or where I can find/buy the components? :bonghit: Rating: 5
