Hello and happy holidays to all This is my first thread and my computer skills are lacking so bear with me. I am a medical MJ user and decided to start growing my own again about 6 months ago. My first grow i used 3 Waterfarms given to me by a friend. They woked well but in my small space, 2'x3'x8', and without a controller and rez, they were a pain in the ass to maintain. Ebb & flow always worked well for me so i started doing a little research. The Multi Flow really caught my eye but the price made my head hurt Also, the seperate rez and controller were a problem as well. I found a neat system that used 2 liter bottles and 16 oz solo cups that used a PVC "grid" with an overflow to controll the height of flood. So i decided to combine the two using 3.5 gallon Multi Flow style buckets.
