honestly i never checked the temp of my nutes in the res. my pen has temp display and im wanting to say somewhere in the mid to high 70's. 76 rings a bell for whatever reason.
GH flora shield is way cheaper than HZ. so i would probably try that at first...
my e&f was hydrofarm mega garden 7gallon setup. my cab stayed about 85 at the canopy, but my air intakes were right next to the res...so im saying again 76 sounds about right.
e&f setups are not as highly aerated as dwc, and this may be a big part of the reason why the nasties dont thrive in e&f like they do in other methods.
also flood tables expose the water to intense light every so often, maybe this sterilizes the water a bit? or at least kills certain nasty pathogens.
anyway around it, i used advanced nutrient 3 part, liquid karma and gh kool bloom products in my e&f res. never a drop of h202, hz or florashield and never a single sign of pyth, root rot, root snot..notta. always used r/o water, not tap. no idea if it matters just puttin it out there. |
