I currently have a 2ft by 3ft space that is about 8ft high. I am using a 600 watt mh they are about 3 or 4 weeks in veg. My exhaust works absolutely terrifically (surprisingly cause i just have a homedepot 6inch inline fan pulling through my reflector) In any case, i can get the light closeee, especially when the temps start getting cold outside. How close should a put the light, its at about a foot above the tops right now *assuming heat is not a problem*. (they are in 3gallon pots). Heres a pic. What is ideal? Should it be closer in flower than veg?

Ummm..think about it this way, how come i get sunburnt while snowboarding? its freezing out side but i still get burnt. Sun burnt not wind burnt. Stick you arm above the canopy of the plants. If you have proper air movment above the plants you arm will feel a constant cool breeze. Your plants feel the same. Lower the light just before the point you start feeling hot spots on your arm. I have a 400w thats prolly 9-13" from the canopy of my plants

i always go bo the rule of thumb of holding a hand under the lamp, and if it is comfortable enough to hold your hand there for several moments that it will also be good for your plants.. but if they look a little heat stressed, move them up a little.. i would think that one foot is a little close, especially for a 600.. i would agree with 18/24 inches as a good starting poing.

WOW thats crazy close, why?

You know there such a thing as too much of a good thing is a bad thing. And those leafs are getting too much intense light. Even my HOT5s (Veg Only) I keep 20" away and I get a 1 inch a day of growth, not strech.

If you keep your lights on 24/0 that will keep them from streching.
18/6 and there going to strech.

Nice looking Plants, way nice.
Myself I get from 4-7.5 oz a plant. I am patient and I veg Hard. I let them get about 2 feet high in a 3 gallon then bury then as deep as I can into a 5 gallon and let them get another foot high.
I prefer to grow 2 Sativa's and 2 Indicas in 12/12 . I just booster seat the indicas so they are all the same height or close too.

Nice job, good advice! Green and healthy. Kept that way until harvest and they will be very productive. For my take on too much light/heat, see my sig link on the issue.

What's the Bloom food drill ?
I kept them green and lush all the way to the flush, that picture is 4 days after flush.
The one's in the back are Diesel. The first time around (avatar) she went straight yellow on me in like the 3 week of flowering, but this time (clones) I knew what was ahead and cared for her properly.
