I have a home made exposure unit from the 80's or so. It has three 4' grow tubes from home depot in it which are about 5" away from the glass with the space to expose two screens at once. Problem is its taking well over a half hour for proper exposure (which took me a while to get to). Point is thats a rediculous amount of time. Any advice?
(I cant afford a cool new unit by the way)
Thanks for your help!
