I'm while waiting for my current grow to finish, I'm trying to plan my next. I'm planning on a small scrog using with a RDWC. Two 10gal totes, 1 for plants, 1 for external res. Still new to growing by this site has been a tremendous help and info source so far .could anyone recommend the type of pump I would need? Gph rating? Etc. If you happen to know the model number or similar model that would be really helpful. Thanks for your help. The vajoo
