Hi, i have 10y experience with soil, but struggling with new EBB&Flow setup..help!

Thanks i will do that tomorrow(i do have a big res. that i can use as my secondary), I can´t use a cooler because this is an ebb flow kit, the medium tray sits on top of the res., but i was thinking about trying to isolate it with Styrofoam, what do you think?

I will be changing the res. in a couple of days, do you think i should flush them a bit with ph5.8 water first, and then refill the res. with the nute solution with the saved ph´d water?

I recommend you check out my journal, as I would only be repeating myself. It provides ample information covering every important aspect of hydro.
