???So the conjoining tube say 3 inch return line, that can reflect light from res and from inside tent back into the root area, do u suggest white or black, since half is inside and half is outside.
I was under the impression whatever logic is applied to an external res should be applied to an internal one. I mean with our without roots in them I guess matters. I guess ill concede and say my logic wouldnt apply to the external res IF the light wasnt reflected into the root res. I use single tote more than external res, i should have read more. I just was getting the impression it doesnt matter in either I guess and im sure others were too.
There is no PVC in the plant sites. Just between them. Light would need to take a 90* turn to get into the plant sites, if there even was any. Certainly not coming from the res...
I feel like we are on completely different points here, so I'll just say you do whatever works best for you. I really don't have a dog in this fight, I'm just trying to help folks out if I can. All I can say is my results speak for themselves. I don't need to fight about it.
This is what my roots look like in this system at harvest time
Somebody better tell those roots they are doing it wrong.
