just wanted to be sure, thank you. how far should be the lights put away according to their wattage? I expect them to be able being put closer because they emit way less heat (IR) than MH or HPS.

Personally I like 2 to 6 inches, tho wattage is a factor here with higher wattage units 300+ 10 to 12, I'm willing to accept a little bleaching. But I'm always watching for any signs of burns. In my experience a little bleaching doesn't hurt anything, tho to much bleaching tends to slow growth a little and causes a hashish like taste. Burns of any kind are just bad imo.

hmm interesting 
You can keep a vegetative or newborn plant under lights 24/7? How can they photosynthesize? I thought..... only thought... i may be wrong, that vegetative plants can go from 16-18 hours. I forgot about flowering.... Oh and how does the irregular lighting patterns effect the plant?

How irregular light patterns affect the plant depends on what stage of growth they are in. If it is flowering it can stress you're plant out and cause it to hermie out.
A few plants out there do not need a dark cycle during growth. Marijuana is one of them. Now obviously the light amount does need to be reduced to 12/12 to flower, unlike some plants that will flower regardless.

Thank you very much! I spoke to a tomato farmer and he was giving me the 18/6 bullshit routine... So very flexible lighting requirements until flowering.... sounds like an easy plant to grow. :thumb up:

But you should stick to 1 light cycle during veg. Don't be switching between 18/6 to 24/0. Pick 1 and stick with it.

Can stress them out. Shifting it once or twice is no big deal. But you shouldn't be doing it a lot. It's way more critical to keep consistent light periods during flowering than vegetative.

this is getting off topic but how about increasing the ratio so it's longer but consistent?
let's say 20/2 would that be stress free for ms. mary jane?

I'm confused.
What I was getting at was that having your light periods jump around from different on/off cycles can be stressful.
Any steady light schedule is stress free.
20/4 would work just fine. I'm assuming that's what you meant.

Autoflowers would be an exception to this correct? They could run 24/0 no problem because of their auto design?

I've heard of them getting funky growth on full 24/0 light. And some wont even flower, even though they are auto flower, on 24/0.

would complete bleaching (yellow leaves due to too much light) of the apical stem/leaves kill growth on a seedling?

Usually bleaching ends up being more white than yellow. Are you sure it was bleaching?
