I find hydro to be simple, if you keep it simple.
Don't try to grow too many plants the 1st time. Keep it small and learn how they grow, you will see fast efficient growth. The one thing you don't want on your 1st grow is a jungle! I had a jungle...I was happy at the end, but lost 7 plants to newbie mistakes/experimentation(doing things you are told not to do, for experience/research).

Goodluck. keep us posted. You have reputable growers/cdot members interested in your project. Z and WS
are 2 excellent mentors, IMHO. you can trust their advice.

Generally Z will allow everyone to try and advise and only chimes in, if no-one helps you or someone gave you bad advice. Goodluck lw
