D3STRUCT Reviewed by D3STRUCT on . changing from sunlight to grow light my plant is on the window sill where it doesnt get very much light,it is about 6inchs big and is already budding, should i introduce my plant onto the grow light slowly or not, it is a 250watt hps, how long should i put it on there for and could someone explain what the numbers 12/12 and digits like that mean, i dont want my plant to die. lol Rating: 5
