thats a nice mod there, Neo420
yeah, thats what you are doing alright, making a combo of DWC/NFT.
it's just no faster growing than a straight waterfarm (nft)
people that modify them this way generally have never tried it without the DWC (air-stones)
and think it is adding air. when in fact the roots get all the air they need up in the hydroton. and that the roots in the lower res get air from the water falling from the drip ring breaking the surface tension of the water in the res.
usually some hydro store owner or web thread has lead the grower to think that waterfarms don't work the way they are made.
now in no way does this help you with your temp issues (other than not pumping hot air into the system) just saying
you want to you could try an inline water pump after the last waterfarm in the chain to the res. not sure it'll work. I think I'd start with a weak pump and work my way up. if I was gonna try it.
I have used WF for years. With airstones. without airstones, modified and unmodified. The OP specific issues is caused by the circulation method.. Its just not feasible enough to push the nutes and cooled liquid throughout the system in a timely and confident matter which will give the OP wild PH swings and inconsistent reading on nutes.
As for the air stones...I had 2 in each WF bucket and 5 or 6 in the main rez........
Also cover the lids of the WF. You do not want contaminants entering the WF or you will catch a bad case of root rot...
Also fully wrap and insulate the WF and hoses for added temp control.
Wrap with mylar? I was hoping to avoid reflective materials up on my deck. Ill def be adding more airstones, but I am very interested in turning the system into a true RDWC so looking forward to hearing your expertise.
So let me ask then, if I made the simplest of adjustments and only added an inline pump between the 4th and 5th buckets returning to the controller, without changing the size of the lines or anything, would that recirculate the system effectively?
I think he meant wrap in legit insulation. THEN maybe mylar..
ditch the air-stones in the waterfarms, I've never heard any positive results from that anyway.
.
i agree.. we are doing a side/side now with airstones in 1/2 our farms, the other 1/2 without (older type of farms, no recir).. today is day 68 of 12/12, and see no diff in the plants.. ofcourse the proof will be in the weighing, but after 6yrs of growing (and still a noobie) you can tell...
@ZACK No difference in the root ball sizes? I ran single WF before and I used to fill up the container with just roots. It would engulf the airstones..... Did you drill holes bigger on the top bucket?
neo... bro, i'd rep you but don't have ability atm... will hit you latter in the day when they open me back up... lol ;-) that system is lucky to have you for an operator... damn nice looking!
305... don't know if you'r pickin up on what Neo is layin... he put a lot of modification to get the system to perform well... a lot of modification... basically could've got parts himself & built it from scratch, which many do. caps, greentrees, waterfarms... all the ones that work well are modified, not outta the box. just for starters, you will need to ditch all the 1/2" line & retap all the buckets & rework the fittings... just for starters.
Thanks for reiterating the problems we've all agreassuming you do a lot more, including more chillers, heaters & larger pumps, then you still have the enormous problem of being outside in a water medium... massive outside temp fluctuations, hence the additional heaters & chillers... in a water culture, without insulation, which you'll also need to do.
Gonna leave that one alone...top on this being your first rodeo...
outta left field maybe... why not just pull the baby plants & plop em into big ole soilless pots... top feed every 3 to 5 days, depending on the size of the pots...??? good opportunity to save yourself a whole bunch of work... and the headaches are just now starting w the weather. hope this finds you well.
