400w or 600w?

Im going to b starting a new grow and was thinking of getting a new 600 watt but wasnt sure if heat issues would be a factor? My space is a 2ft x 3ft by 9 1/2 ft , or should i just stick with a 400watt?

I would reccomend the 600 as it has the best lumen/watt value, with an air cooled hood and the balast outside of the room you should be fine for heat.

its just a regular maxi wing and it being a digital ballast it shouldnt put a whole lot of heat off i have a 200cfm carbon filter with a 270 cfm fan so it should keep most of the heat pulled out with such a small area only 54 cubic ft ?

anyone else have any insight?

600 w is wat you want mate more lumens more bud growth better mass over all growth. Space seems a bit small make sure u got, a good air intake , outake .

cool will do thanx guys

600w is the way to go.

Well worth changing over, you'll be a believer after you see the difference in bud size & production.

Skip em both and go with the 1000's

lol^^^^^^^^^^^^^^^

For me, it seems both can be good but I will suggest you 600w because of there growing condition. I think you should be go for it and hope will be helpful for you. After that you can tell here about it. Well, do you have some pictures of the place where will you grow???

i ended up getting the 600!!!!

I have a 3 x 3 x 6 room and last year upgraded from the 400 to the 600. I've since bought the air cooled hood and a bigger fan to deal with the heat, but am very glad I made the upgrade. I also bought the dimmable ballast as in the summer, my heat is a bit high, so I'll either shut down for July and August, or I'll run @ 75% until temps get back under control.

You'll like the extra 200w I'm sure! Good luck mate!

Smart move, you will prefer it!

Good..600 is most efficent.

after looking at my $500 electric I'm just going to run my 2 600w vs a 1000w and 600w. glad you went with 600's

I would definitely reccomend an air cooled hood. I bought a cheaper bat wing hood and now i cant even run my hps in my closet because the temps get up to over 30° and my plants start showing signs of heat stress within a few days

600w ----the more light the better.

I run a 400 watt in my cab dont go over 400 i cant run full power when doors closed so im gonna get a cool tube so itl help a bit and i got a 180cfm filter so when i run 200 watts with doors closed it stays 84f
