hey guys heres my new grow room, wayy bigger than my old one. its 4ft 2inches tall x 3ft wide x 15 inches deep

i have two 4 inch tubes running in and out. and a squirrel cage fan blowing air out.

i was using a 70w hps for a while but i don't have it anymore so i need to buy one.

i am either going to get the 250w or 400w from high tech garden supply

but i can't decide if the 400 will be overkill.
what do you guys think?

btw all the plants in there are female, the two ladys that are almost ready are 3 months 4 days old. i can't decide when to harvest, maybe a week or two? i've just started flushing

250w will do great but you just built a new bigger grow room how long till you build an even bigger one :) 400w might be the way to go unless you are happy with the size you are at

also is that the best price you found?

Your going to probably have problems keeping temps down with the HID in such a small space. with 4ft of room allow 6in. or so for bulb and reflector, then the plant tops need to be atleast 12inches away from light. if you have 1 or 2 gallon pots 6 in tall your only giving yourself about 2 foot or less of grow room. looks like good results with those fluros. keep it simple

400 watt is probably going to be too much for that area. However when you buy the HPS you also need the ballast and if you go upto the 400 you'll probably have to rebuy everything. It's a toss up, get the 400 and worry about venting. Or get the 250 and if ever needing to upgrade paying the $$ for it...

i'm leaning towards the 400 because i probably wont have the money to upgrade in the future

looks good! yours is about the same size but your using 6" ducting and i have 4"
also you have room outside your grow room for fans, mine is a little more enclosed.

From what I've read you should be able to vent out that 400 watt, but it'll just be something you'll always have to keep your eye on. It's a shame you've only got 4 feet of height though. Easily a foot for the container/pots, a foot for light room/hood. Then you've only got room for a 2 ft plant. CFL's aren't that bad, and in a small area you can put them almost on top of the plants so that's probably the easiest/best for what I could see for pics. Maybe stick with the CFL until you've got a little bigger space?

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...:razz: 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

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

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

http://www.htgsupply.com/viewproduct.asp?productID=48943







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

http://www.htgsupply.com/viewproduct.asp?productID=47929



And you can always go cheapo and DIY...

$54.95 for the ballast and socket...

http://www.htgsupply.com/viewproduct.asp?productID=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...:razz:

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.
