You can grow big plants to put outside but if they are weak they will fall over to the winds outside. So make sure they get plenty of light and some Silica to strengthen the stem. Its more important to keep your light on an 16/8 schedule so they do not flower when you put them outside in spring.
im getting ready to cut clones for my outdoor, they will b inside under lights till 4-20-2011 thats the day they hit the dirt..can't think of any thing better to do that day other then wake and bake and plant the out door grow..
