I am going to be teaching an 'Intro to Hydro' class at 9am to 11am this Sunday (when it's cool out) at Brick N Barn. My goal is to give 1) broad overview of systems (I have sample systems for you to see not just hear about) 2) my real life experience (3) answers for your questions and 4) show you a simple system that you can create (without spending lots of money) that will pretty much take care of itself and get you started growing and feeding yourself and others. You can make reservations at 760-651-2635, seats are limited.
Some background: After retirement, in 2018 I completed course work at Cal Poly, Pomona. I received a certificate.in hydroponics (but as I will share, the real learning is in the doing). Here is a fun little video to show our start in 2018.
