hehe im sure they can go without air just wave some newspaper at them now and then.. hey what light is that? if its cfl you got no problems if its something else you should get a fan because clone ( so i predict ) is the most fragile time for a plant and it need everything right or it dies from any kind of stress.. i dont clone i find it strange... i dont like hydrolics eighter.. im against experimentation with living organism type stuff... man hydraulics is freaky tubes and bubles and shit.. :weedpoke:
