Thanks Dylan,

I've been looking at a few HPS setups, but I'm not sure if I'll be able to keep the temps down.

My space is 80cm x 40cm x 140cm, and they are in 12" pots. If the light stays high and the plants dont creep too tall, might I be able to get away with no i/o ventilation for a 400W hps? The door will be open quite a lot and I have a fan too.

I'm bidding on a 400W to come through in about 2 weeks, sounds like a good time to start flowering.

Thanks for your help.

I shall outline my basic setup for you, and it is basic. 2 vegging four-way plants 1 in straight compost 1 in perlite:compost 1:2 4 18w 1350 lumen cool white fluoro tubes I'm renting a basement room with nowhere to ventilate to, but it's cool enough and has a draft with the window open 24/7.
