I have a 3 foot tall grow space and ive been debating for a long time how to set up the lights

Should i use 150 watt hps? because ive been reading you need the plants far from it for it to work. Or is there a way to cover the light?

or should i switch to another type of light?

I don't think 3ft is going to be enough to grow my friend...especially with an HPS

That is a little short. If it was 3 feet minus the pots and light etc, then it may be feasable. 3 feet=36 inches. pots prob at least 8 inches. light well at least the 150 I had took about 6-8 inches. leaves you 20 inches for plant and space bettween plants and light. I did have our 150 as close as 6-8 inches. that leaves you with 1 foot plants in the best scenario!

Not saying it's imposible but It would be a great challenge!

im not looking for big plants, and my friend used to grow small amounts in a size that big so i know it can be done.

Do you mean distance because i have risers to put the light closer to the plant

well then if 3 feet is to small i can bump it up if i have to, but ive seen people with really interesting set ups that are that long

Yeah I guess your right, like I said it can be done, this was a little cab I made last year with a 250 hps and homeade cooltube. I just used it for vegg and mothers, very hard to keep cool even with cooltube. It's not even 3 feet. I was thinking of doing a little scrog in there.

i use 150watts of hps for my lr2's, it's usually enough light for four or five of em and i usually keep it no more than a foot above the tops of the plants. i don't know where your getting that the light needs to be far away for it to work... the further away the less lumens your getting to the plants, the only thing you need to keep an eye on is your temps, computer fans might not cut it. i use small osculating fans.

a glass tube that goes around the bulb with a fan to move the hot air out.... it's supposed to be hooked up to ducting

whats the point in having a cool tube if it's not being vented to the outside of your cabinet? you should have air inlets and outlets to keep your temps down.
