Clones and Growns

hey, well I've posted a few threads relating these various topics but i come armed with (albeit) shitty pictures.

So ive got two chambers, a veg/mother chamber with a 400 MH and a cooltube. No ventilation or heating problems with that baby.

However, the flowering chamber is much bigger, about 1.5 times the size running a 1000 W HPS and 15 grapefruit clones. There is a large house fan for moving air inside teh chamber, about a 95 cfm fan doing air in, a 130 cfm fan that connects to the carbon filter outside and does the air out, and finally, a 115 sized inline fan connected to the cool tube. The air in for the tube comes from outside the chamber and the air out (obviously) goes out into another room. Temps were baaad at first but are now steaader around 74 F. However, the light is a good 2 feet above the clones. I know they need higher intensity, but I do not want to harm them, so I'm takin her easy. Anyways, we were using anti wilt on the babies when the heat was near 90, but I think it may have damaged them slightly. There has been very slight growth from them in about almost a week which I am hopefully attributing to stress, n heat, and I did use nutes, and was scoled and haven't since. Other than that, should I increase the light proximity to the clones, Should I eventually (when i have the money) buy a 300 dollar fan (im from vancouver and have had a tough time finding high cfm fans for under 300 bucks even thoug there are a shitload of hydro stores around). Here aer som pics, thanks yalllll.

...??? pictures lol forget?

yo bud, you dont need to spend quite that much. Power grow on renfrew has 600CFM fans for like 180. There centrifugal and are very quite. I want to get one, but i dont want to spend the money.

BTW i'm getting some cool tubes too, need em. You should come check out what i got goin on now. It's pretty sweet
later bud
