2ft is plenty of room, i will be doing a lot of LST

but maybe i better stick with the 250 because its so small....

ahhhh its so hard to decide

if you have a cooltube go with the 400w if you dont go with the 250watt because rising heat will be an issue for sure.

nope no cooltube, i was hoping the squirrel cage fan would do it, it sure does move alot of air

This is the smartest post I ave sen in a while...

Get a cooltube... and go with the 400...

You will thank yourself when harvest comes...

Proper ventilation is key...

But it can be done.. easily...

I used to run a 600 HPS in a homemade tent... 20"x36"x54"... no issues...

Upgrading is expensive and wasteful...

My two cents...

Just to re iterate my point...

The better buds in more quantity will more than make up for the difference in initial cost and electric bill...

Get a cooltube... My plants can touch the glass with a 600 inside....

thanks dude, i haven't been able to find a cool tube that is cheap and 4" inches. maybe i can make one? i don't have very much money thats why i'm buying the cheap lamp.

i would hate to have to buy another lamp in the future when i could buy like a grow tent or something instead, or another 400w

buy the 400w and if to hot build bigger grow room lol

haha thats what i would love to do, but i dont really have the room lol

I like HTG... especially their Digis.. I have 2x 600W digi from them...

This one is $231.95 WITH the cool tube...

This one is $189.95 WITH the cool tube...

http://www.htgsupply.com/viewproduct...roductID=47929



And you can always go cheapo and DIY...

$54.95 for the ballast and socket...

http://www.htgsupply.com/viewproduct...roductID=45693




you would need to get the cooltube separate... $85.95




You do not need a 4" cooltube...

Just use 6" duct with adapters at the fan...

A 6" tube is really what you need...

Remember what you said about updating...

Everytime you buy something.. make sure it is the last you buy..

Buy the right shit the first time and be done...

Al the stuff I used in my tent is in full use today in my op many times bigger...

I hate waste.. and crap laying around...

Do it right ... do it once... and enjoy...

hey good idea man thanks,
i think i might get the 400w with the cooltube for 189. thats a really good deal
i didn't even think of using a reducer. so i can go from 4 to 6 inches then back to 4 no problem?

what i would probably do is have the squirrel cage sucking air from inside the grow room, blowing it into the cooltube then out the exhaust. then i would have a small fan on the intake blowing fresh air into the room

i know what you mean about waste, i hate having good equipment laying around, especially with the economy like this.
