hahaha there is no debate there it is fact, plants grown under 24/7 are under more stress (hemi) and cost more, and they strech 25% more than 18/6 there is NO need to go 24/7 with any plant ever!!!!! I like to rest between dinner and breakfast, don't you?? I know a guy in AU who harvests almost a pound in one bud (i have pics) he uses 18/6 and if he is wrong so am I. lol you will never get great plants from 24/7 due to stress period, it is unnatural and does not work. You may get good results but i gaurantee better with some sleep!!! i promise!!!
Hmmm, does sound good. Maybe ill switch them over to 18/7 18 hours on 7 days a week today. Going from 24/7 i don't think it will cause much stress.
I would think not, your plant will love you for that, and time watterings right before lights out or right after lights on, oh yea, a light timer is like 4.00 US at lowes. Make sure it is a heavy duty and will handle your wattage, it will say on the package and the folks at those store are more than willing to help.
dont spend $50 on a 2nd 70w, you can get a 150w for $35 (if you havent already) http://www.e-conolight.com/cgi-bin/shopper.exe?preadd=action&key=E-hc1h151z i got this the other day, only drawback is you need to wire up the cord since it doesnt come with one..... im in that process right now
