Hello everyone I'm a new grower living in the Maryland area. Basically I'm thinking of buying the cool cab hydroponic system from 4eversun.com.This will be my first plant. I already know it would be cheaper to build one myself but I have money I'd rather just buy one i just want to know from an expert do you think this is a good choice? also how many plants do you think i should put in it? what strain is a good choice? Is it safe to order seeds from nirvana? Thank you!!! I really appreciate the help.
