Back to Basics (but better!)

So this is the first time I've tried hydroponics and I don't think I would do it again unless I had a nutrient chiller. None of the roots had actually dropped down into the nutrients at all. They merely stayed inside the net pots. I think this was because the nutes were too warm and invited disease. The roots did look brown but the issue with that is that when you use House & Garden's Roots Excelurator, it tends to leave the roots a little brown due to the colour being left on the roots so it's a little hard to read. I think for now until I get a nutrient chiller I will go back to Coco as the medium as I had way better results using that.
