You need to get alot more responsible if you're going to have any hope of seeing this through..
Either get a timer, or run them 24/0.. If you're bad enough to 'forget', then I doubt you're timing is the greatest on days you remember.. Perhaps ruderalis hybrids let you get away with that nonsense, I honestly don't know, but that kind of crap will herm out most plants eventually.. Plants have not evolved to cope with inconsistent lighting.. If there is one dependable thing in nature, its the light cycle..
Now I'm not as against stealth grows in parents houses as most ppl on these boards, because they will either be done with secrecy and effectiveness, or they will be short-lived, and ultimately no legal risk to the homeowner.. What I can't condone is creating a sketchy fire-hazard..
With any grow, of any type:
-LIGHTS MUST BE SECURE FROM FALLING, GETTING WET, OR COMING INTO CONTACT WITH ANYTHING IGNITABLE!
-WIRING MUST BE PROPER FOR THE SETUP!!
(REMEMBER INDUCTIVE LOADS ARE MORE TAXING ON WIRING THAN RESISTIVE, AND GROWING USES ALOT OF INDUCTIVE LOADS..)
-EXTERNAL RISK FACTORS LIKE DOGS MUST BE MANAGED..
-VENTILATION IS 100% NECESSARY!
Sorry to be so blunt, but it had to be said..
On the positive side, your plant is looking pretty good right now.. A cfl or two is adequate (or maybe even ideal) at this stage, but that is going to change FAST..
Question: How much money do you think you could afford to spend on this within the next 2 weeks? I really think you're going to need a bit of gear..
