My plants are in umm..... I think one gallon black square tall pots and the soil is beginning to dry too fast. The plants are about 24-26'' tall and they need to be watered every 2-3 days. So I water them twice before I use nutes. I use fox farm ocean potting soil. Is this ok or should I transplant them?
General rule is 1 foot of plant per gallon size of pot. A 2 foot plant would need at least a 2 gallon pot, if not bigger. If they are still vegging, you will want to put them in even bigger pots because they will double in height during flowering.
