more or less watts in veg?

Put this question on a different thread and got no help,gonna try again here. I have a 1.2x1.2 tent with 6 clones. I was told today that I would be better off vegging with 400w rather than the 600w I'm using. Is this true?

I would go with the bigger light since you already have it as long as you can keep the tent cooled off why not.

It should be true to some extent. You dont need the penetration that a 600w provides when vegging, but certainly when flowering.

I have both the 400w and 600w hanging ready for flower as I was planning on using both for flower but my temps are at 29.4c so I reckon I'm gonna have to stick to a 600w flower. I switch them to 12/12 at 18inch and I want to get there fast,to me that means leaving it to veg under the 600w. I respect the info I was given as the guys the one who taught me,he been growing 19year and you gotta respect that. My temperture is fine at what it is though ain't it?

i think the "norm" is using the smaller light to veg , but that is unessacary. it wont help to use a smaller lamp unless you have too much light or your temps are too high. stick to the 6.

Agreed. From everything I have ever heard, read, etc. it's not going to make much difference. Might save a little on electricity, but not enough to matter probably.

50 to 75 watts a square foot is required for optimal growth as a general rule. That being said I am closer to 100 watt per square foot and believe the more the better IMHO

damn it all ive been using 400 watts of t-5's for veg cause I like that spectrum but sheet mang maybe I should just 18/6 that hps cooltube for veg with some 54 watt t--5's as supplemental during the veg. Good thread my man!

Ok but the temp at 29.5c is fine. I did put on the 400w and it only when down 1c so I believe I had it right with the 600w. We live and learn!

When I first started, I used daylight bulbs in a regular 4' fluorescent fixture. As far as the veg stage, I can't really tell a difference. Flowering is a whole different story of course. lol
