See that ring? It is a drip system, so the answer is yes, they do get nutrients. I am his friend and have seen the system, and the roots get plenty of nutrients when it drips. One clone from my plant was in his system, but had died from the solution, its been watered down, and I think these seedling/clones are bigger and can take the solution better. So far they look good, besides a few burns they have. We will try to keep pictures posted. This is my plant, Eve, the momma of many of the clones, it lived with only shitty sunlight for a long time, but it is now in hydro and with better lighting and is making immense progress.
