PHing this system is so easy. Cap off flow from the reservoir, let the pump fill up the cooler, close flow control and kill the pump, and I'm left with almost all my water sitting in the res. 20 gal. Drop it down and uncap the flow. Takes about 5 minutes. Loving it.
Got 4 plants in the system now after a week in presoaked rockwool cubes, & root harmone. 4 sets of leaves, looking good. PPMs are at 100. Will have pictures soon.
 
Room temp avg...75 degrees
Water temp avg...58- 62 degrees
The cooler for a reservoir makes water temps sooo easy to manage.
 
Will be following this philosophy...
If your PPMs rise and PH rises nutrients are to strong.
If PPMs drop and PH rises, nutrients are to weak.
If your PPM drops and PH are basically stable then you have found the right mix for your plants.
 
Using tap also, 035 PPM. I'm guessing it's chlorine, doesn't seem to bother the plants though...Will be getting myself a R/O system soon, probably by next grow...
 
Got roots this morning showing through the net pots. Gonna keep PPMs low (65) till they start dropping. PH is crawling really slow, yesterday it sat at 5.9 forever before finally popping up to 6.0 around midnight. Dropped her down to 5.5 and this morning it's only raised to 5.6, so all is well...Will have pics soon.
 
Sounds great dude, I am hoping to do this, aeroponics or NFT/PVC
My cloner would be considered aeroponic, but other than that I have no experience with either. They are both popular, but more advanced I believe than DWC. YouTube is full of How-to vids on both types. Good Luck!
 
dang you have a lot of nutes! I'm only using Flora Nova Bloom. Nice setup though, will be following yours.

Thanks man, I've heard of people using only bloom with nice results. My philosophy is if you have it, why not use it. The Nova Grow is some amazing stuff, makes em fat...you should try it. Will be following your grow also.
 
This morning I have more roots, but one plant is still not showing. PH has been @ 5.7 for almost 24 hours. Also put the domes back on yesterday morning and started spraying again. Will continue this till I get roots through on all...
 
Backed off on the nutes yesterday and changed the reservoir. Roots are through on all now. Ph is sitting again @ 5.7...PPMs are slowly rising...So I'll hold off on the nutes for a minute...
