Size really depends on your lights (how much area they can cover) and how big you want to grow the plants, (how big the containers are). I'd say get a 5gal container, and measure it to see how much space 4 of them would take up. Maybe you plan on finishing in 3 or 4 gal containers, but at least this way you have the extra room if you need it. You can mount your oscillating above the canopy so it doesn't take up floor space.

I'll be following along... I'd like to grow around 4-5 plants next time around :jointsmile:
