Hey I'm just getting started out and have a batch of seeds on order. Is the system setup designed to grow out the seeds only or to grow the plants entirely. I was very intrigued to see your setup and may consider doing something similar on my patio mainly because I already have ALL the items on your list with the exception of the rock wool and chemicals. Since I'm a big aquarium fan I have 2 40 gallon empty tanks sitting on the patio a few filters, diffusers, lights you name it I got it! It would just be a matter of putting them together and setting it up.
