First off i wouldnt be buying any kit off hydro shops in ireland bud, they're about double the price of the shops in the uk. Make a list of what you need and then price it online, its safe out and if you get it all at once the delivery will only be 20snots. I recommend 3countieshydro, i dealt with them and had my stuff in 3 days. No need for a tent either if you're going in the attic 'coz light leaks wont be an issue. Make up a frame out of 2x2s and cover it with builders plastic. Also I bought a kitchen extractor fan, a really powerful one, from b&q yesterday. Cost 80 yoyos, i wouldnt dream of buying another inline fan they're shite

Attics are vented and uninsulated so it will drop to a few degrees above whatever it is outside so a heater with a thermostat would be the right job for you.
Your obviously going for hps, That will keep them nice and warm in the daylight hrs. You dont want the temp dropping below 17 at night. 15 rock bottom, any lower will stunt your plants. I try to keep a constant temp of 20 but its difficult, and im using a bedroom in a well insulated house. I think 600w is a bit of overkill if your only planning on 4 plants, BUT if your thinking about expanding your grow in the future, go for it

Anyways keep us posted on whatever you decide on, and happy growing,

Enjoy:thumbsup:
Corkboyhigh Reviewed by Corkboyhigh on . Is Attic sufficient-heat wise to grow ? Hi there guy's, I'm new to the site and growing in general so I'm here for some of your knowledge :) I havn' got any growing equipment just yet but I've been pricing it over the past couple of months and I'm just about ready to purchase the tent, lights ect... But for now before I do anything I'd just like to ask you guy's is the attic sufficient to do your growing ? I got up in the attic the other day and there is plenty of space if I get flooring put in which I have already priced. But Rating: 5
