I have posted this in a couple other forums..... I found a lot of different modifications trying to circulate water from a reservoir.... Some used the GH recirculating kit.... That was well intended mod. on their part, but a rather feeble result.... Let me offer this to all my fellow WF'ers...
Simple, low cost way to circulate water with an existing WF drip ring pumping column.. it's as simple as putting a standing 3/4 column of water in the grow bucket that refills from the reservoir, not the grow bucket.... This water column is where the drip ring now pumps water for the plant.... As the water is pumped out of the water column gravity refills it from the reservoir....... I knew I was on the right track with the water column, at first I had the damn thing in the reservoir....
The water column should be thin wall 3/4 PVC, it has a bigger ID than the sch40 3/4pvc...,and the pumping column is a better fit in the thin wall .This setup will work with a GH reservoir and controller... or a roll your own..
. An 8 bucket WF, setup in this fashion, will circulate water 7 times faster than a single setup.... 7 times faster than a GH recirculating kit.... .. This is a pic of the side location for the water column, put there to line up with the existing hole in the top bucket... The hole in the top bucket stabilizes the water column and keeps it in place...
.The inlet to the water column in the reservoir is 1/2"threaded to3/4"slip, reducing ell... a 2-1/2" cut off riser and a 1/2" threaded bard on the out side.... Teflon tape all threads, the cutoff riser should get a couple extra wraps for a tight fit... Only one washer is used on the inside. The water column parts came from Home Depot.. Don't glue the water column, the slip fit is good enough.....
For only a couple WFs 1/2: feed/return lines would be fine... The 1/2" setup return uses the old sight/drain 1/2"barb to connect back to the reservoir... For more WFs 3/4" inch lines would be better..Return 3/4 line water would exit the grow bucket thru a 3/4" grommet/barb.. The water column fittings will still be 1/2" at the water column..
I always use a scrog screen with my WFs and sometimes want/need to move it... Instead of a permanent screen I made this one out of 1/2" pvc... the black piece is 3/32" abs to reinforce the plastic handle of the wf... Without some reinforcement the hose clamps will break the molded handle when you tighten down the 1/2" tee... Some zip ties secure the 2x4" plastic coated screen.. No need to glue the frame, it seems to work well enough without it... a plus being you can take it apart if need be... Not much to it, 4- 1/2" 90*ells, 4 1/2" tees, 4 hose clamps and enough 1/2" sch-40 pvc pipe for the frame... This a 24"X30" screen, but I think you could go as large as 36"x36
If you love your waterfarming, but it gets to hot in the summer, this insulated one plant with reservoir setup may be what you need.... For this one I've pressed into service 2, 5-gal Igloo water coolers... This has the same drip ring mod. as the first.... You need a 13/16 spade bit to drill the holes for the return line fittings to the reservoir... The same 2-1/2" cutoff riser is used without cutting... The spout hole in the igloo is just the right size for the fitting, and in a good location for the water column... The igloo has strong handles, perfect for attaching a scrog screen.. A 1" foan cover fits snug in the basket over the drip ring... Covering the drip ring and using the split foam insulation on the tubing, should get you through a 24 hour period..... I still have a few changes in mind to make...
wow thats insane you just blew my mind ....ingenious dam you got that off.....I can grow in the summer thanx.....I'm haveing problems with root rot ive been using h202 works great and i changed up dripper to let it dry out ...and I read dukes diary he only leaves them on for like 15 minutes on 4 times a day .....I have been reading about these nutrients advanced makes that keeps the ph perfect ....any input would be appreciated
I was wondering to myself how mold, fungus and such stuff gets into the water... If it doesn't come in the water the other source is most likely the air being pumped through the system....
I had these filters as spares, along with some double sided tape.... They draw with no back pressure, so no extra load on the pump..... They should filter out anything looking for a water home.....
