kactai Ugh that’s suck. I’m not very knowledgeable about DWC. Is this a common problem?

pompusham I use great white + hydro guard in my Reservoir and it keeps organic buildup out.

hem-p Basically with DWC, the goal is also to keep the Temp of the water less than the temp in the grow room. I dove into DWC with no way to do so when I started this crop, results were roots discolored & covered in sludge. Cutting off the roots then led to a 14 day healing process for the plant. Had to learn, luckily it seemed to be the smaller plants that died off.
