I dunno man. The more strains you have the more trouble it is. Like if you have all of the same strain, all your plants are pretty much gonna grow, and flower at the same rate. It's important to have a pretty consistent plant canopy to get the most out of your lighting system. If half your plants are way tall, you're gonna have the light too high and the shorter plants will be missing out. I would do some training to keep them all pretty level to each other if you're gonna have a lot of different strains.
