Well I've finally moved and am looking forward to my new grows. This place is pretty small though, so I don't think the 400 watter is going to see any action for a while.

Like I said, this new place is really small. The only space I've found that can be used to grow is 19" wide x 21" deep x 30" tall, and believe me, I've looked everywhere!

I'm thinkin' that a 150w HPS will fill this space with light pretty good, but I would definately like to squeeze as many watts into this space as possible, maybe a 200w HPS? or even a 250w HPS? Keep in mind that whatever I use, I am also thinking about supplementing it with a small MH (like 70w) to keep internodal spacing short and to help dense the buds a little.

Any advice or suggestions about ventilation would be great also!

OH, and keep in mind that I'm on a budget.

I'll be scrogging and have a veg/mother chamber as well, so everything will be grown from clones.

Thanx for any input.

a 250 hps would be good in that sized space.

[Harry Gypsna]

Will u aircooling the lamp??

[sm0kateer4204]

i have to disagree a 250 would be too much heat for that sized space you could get a 150 hps in there but the 70 watt wouldnt do so well in there with it because of heat unless you had really good airflow, i suggest you buy a 70 watt hps and put both 70 watts in there that'll be 140 watts of mixed spectrum lighting should work well i suggest you do lots of low stress training to keep plants in that small space. good luck

Thanx for the replies y'all.

No, I won't be aircooling the light seperately, but the whole space. The exhaust will be at the top of the cab.

My space is a little smaller than NGB's Stealth Cab's flowering chamber. He used a 150w HPS with good results.

My space is 2.77 sq. ft., I think I'm gonna go with the 150w and supplement with a 70w MH. That's 220 total watts and about 80 watts per sq. ft. :o

What kind of cfm am I going to have to move to cool that? Any ideas?

Thanx.

you wont need much of a fan toka......
100cfm should be more then enuff.....
let me dig up a web page i have that has a calc for that.....
{edit} i cant find it all look on the net in the morning....

Go for the 250 man iuse a 400hps in a really small wardrobe with a heat spreader and u can get the light loads closer to the plants and it gets rid of the heat spot directly under the light and gives a more even light spread.peace

[wylde1]

id say go for the 250 aswell. i mean runnin costs wont b enough to even consider thinkin about, the heat off them aint that bad and i doubt ur'll have the ballset in ther aswell? (i leave the door shut with no venting on a 4x4 closet and i leave the ballest in ther aswell) so u wont need a huge fan. also when u do get the 400 up n runnin again a 250 makes a nice veg light to feed a 400 i find.

plus human nature being what it is i recon after havin a 400 if u do go with a 150 u wont b happy and wish u had gone for a 250 even if it aint the wise move. and u shud get more bud with it.

[tokeAcola]

thanx for the replies y'all.

Now I'm thinkin' about goin' with the 250. I think the extra wattage will give me a slightly better yeild and more trich coverage. Maybe I won't supplement with the MH. Maybe I'll just use a small MH? 30-50 watts? would that even make a diff? lol

OH, well, I really appreciate y'all tryin' to help me out. More advice is always welcome.

I still have a while to decide since my plants barely germed a few days ago and I have a serperate veg space. woooohoooo! go rubbermaids!

Peace.
