2 foot from the plant top is the optimum length with a 400w HPS - Plants are pretty unpredictable in terms of height... if your plant gets too big, you could always tie it down a bit ?![]()
I just had this problem with my 400 watter. I didn't think a 400 watter could bleach the bud like it did. Was I wrong or what. Here's a picture of one of the bleached buds next to one that was farther away from the light. It still smokes ok. Nothing wrong with it other then it got bleached.also, even if teh temps are ok, say in winter, dont keep it closer than a few inchs. All winter I had my plants at the glass it was so cool. I ended up with some bleached buds, and that is not reversible. No closer than six for me. I try and keep at least eight. I see grows all the time and the buds a foot easy or more look pretty nice.
BingoI don't think the OP wants to know how far away to put the light - they want to know how far the light penetrates, for instance - can it still penetrate a 6ft plant? 8ft? How big a plant will it penetrate?
I'm kinda curious about the answer myself...
are you in the right thread or just plain ignorant? The guy wants to know about lumen depletion, do you know what that is?????????????u mostly have to look at its genetics.. thats how u can tell if they will get big or what but none the less u can grow them big just depends on some strains. some of them are meant to be short and stocky
Thanks to everyone who repliedanything above 3ft and lumen depletion will be a problem.

Another load of rubbish, you wont get good results with 4-6ft plants with a 400 watter!vegg tell 2-3 ft tall then flower them
this is what he wanted
