I am currently looking at a 40 gallon single reservoir... sits basically perfect in my 4x4. It is white, will this have an affect? I plan to put 4 plants in net pots through the lid.That's really up to personal preference/opinion/experience.
Science says higher absorption rates at a pH closer to the higher side of the scale. But I would recommend you do your damnedest to just keep it within the 5.5-6.5 parameters at all.
If you're going to be doing DWC in a single 5gal bucket, the 3-4 gallons of water it can hold without drowning the netpot, will be a constant, DAILY if not hourly, battle for you to keep your pH stable at all. And let's not even start on keeping your waters temperature under control.
If you've got any option to upsize your container to some kind of BLACK "tote" of a LARGER volume, I can't tell you how much easier it will make your run go for you. Just cut out a hole in the lid that will fit your netpot. Even if it's one of the models built into a 5gal bucket lid.
That will help you immensely. If I were you, I'd get a second one, have it outside the tent, connect t then with a 2" ABS pipe and 2 2" bulkheads. Then use a water pump to pump from that reservoir up through some 1/2" PVC to a waterfall going into the side near the top of the totes wall, of the one in the tent. This will keep your water always moving and oxygenating and you will no longer need to use an air pump or air stones.I am currently looking at a 40 gallon single reservoir... sits basically perfect in my 4x4.

It's no drip. It's waterfalls. Nothing high powered or anything, but certainly not a spray or drip.I like your set up there. I may move the 40 gallon out of the tent and pump to separate buckets in the next grow. Is the drip/jet of water enough oxygenation? I am using two 4" aeration discs with a two outlet 4LPM air pump for now
68F is perfect. Higher and you start limiting DO, lower and you start cooling the roots too much slowing growth.what temp to you try to keep your reservoir?
