quick question, can you not leave them outside to flower?.....that would really be the best for the plants. but if i had to bring them in, depending on size i would probably flower them with the 400. since the suns light cycle is not 24/7 here if you were to bring them back in and put them in 24/7 it could shock and stress your plants, it could work but the chance of them becoming hermies are more likely. and as for how close the light should be, as close as possible without the tops burning, just put your hand under the light and lower your hand until it doesnt burn it....that should be alright for your plants. good luck
keeko Reviewed by keeko on . Outside to Inside - any Ideas? I am two weeks from harvesting four indicas from my closet garden. I have two eight week old sativas growing in five gallon containers in my backyard, but due to neighbors nosiness and lighting issues, cannot leave them outside for too much longer. I was planning on bringing them into my closet when the current crop is harvested. I have never done this before, and was wondering if anyone had any advice about this. Will they be able to handle the HID? I have a 175W MH and a 400W HPS - I was Rating: 5
