Im still thinking about whether to take cuttings and do a SOG grow immediately after..still not a 100% on it though

Get a 150w then. Way overkill with a 250w.

it's completely relevant, the lumens decrease dramatically when the cfls are further away from the plant as opposed to the HID, if you ever get a light/lumen indicator you'll see what i mean.
An air cooled reflector is designed specifically for HIDs to be placed closer to the plant so the heat that the bulb produces is ventilated out, it's not the light intensity that burns the plant it's the heat.
And i grow my plants as close as i can get without burning, which is about 8-10 inches.
And besides he said he wanted a 250W hps which in my opinion is INFERIOR to the CFLs with the comparable wattage. The 250w HPS does not convert electricity to lumens as efficiently as the 400 or 600w hps.

i disagree, 150 watts over 24 square feet isn't enough.
Go with the cfls if you can't do the 400w hps

Why the fuck is he growing one plant in a 24' sq room. Thats stupid!

Thats the problem I dont have the money, I'd have to work for it. I can get a decent HPS system for £200 but then I have to invest in ventilation (another £200-£300) So Im either spending over £500 on a HPS system or £50-£60 on a single CFL. If I knew it would make a significant difference I'd go for the HPS..

Yh I know. I've bought a single CFL for vegging. Im just thinking about flowering.

Still think 250 is overkill. But hey not my bill. Have fun trying to cool that beast. Hopefully you have great ventilation

Thanks I will lol
And if I decide to use CFLs ventilation isnt going to be an issue. Just opening the doors a few times a day should be good enough.timeismoney1

Actually cfls will get pretty warm in a enclosed space. Have a lil table fan and youll be set

A fan dosn't cool the grow room down it just circulates the air within the room. (If the temperatures 30c in the room then its circulating 30c air) I'd need to buy an intake fan if temperature became a problem (this would bring fresh air into the room) Instead of buying an intake fan it would be easier just open the doors 5-6 times a day. It would have the same effect.

But do I though? If 2 CFLs have the same effect as 1 HPS then why bother paying £500 more for the HPS?
