Nice your the MAN ZAN before I switch too 12/12 should I flush the system with only water for a day or just switch from the veg. nuets. to the bloom nuets.?
pskipper Reviewed by pskipper on . Changing to 12/12 My plants are at about 15", My question is when changing to 12/12 will my plants double in size? When changing to 12/12 should I drop the times slowly to get to the 12/12 cycle or should I go straight from 18/6 to 12/12? Rating: 5
