Growing two indica strains in two 5 gallon dwc's currently and now that my sativa seeds arrived i can grow them. Going to place two sativa strains in a hempy bucket. Should I do 5 gallon hempy buckets so my plants are about the same height at start? or 2 gallon buckets? Afraid if I use 5 gallons they will get too huge also they wont reach res during veg. Probably vegging 2-3 weeks. Any input is welcome, thanks! Letgo
