Hi,
I'm new here so I just thought I'd introduce myself.
I'm a long time smoker but a growing newb, and I've been lurking here for a couple of weeks soaking up all the info needed to start my first grows.

I've got 11 little plants on the go so far which are all from bag seed so I'm just going to plant them out in my garden to see if they come to anything.

For my first indoor grow I've decided to do it properly and ordered a bud box xl a 400w hps light and a ruck 125mm fan and carbon filter.
I'm planning to grow 4 plants at a time in my loft which is plenty to keep me going, and I'm going to partition off a clone/mother area in the bottom of the tent with flouros.

The only thing I need to work out now is how to keep it cool in the tent, is anyone using a 400w lamp in an xl, and if so how is it temp wise?

Also, if I grow in soil which is the best food to use (I'm growing BrainStorm)?

Oh well I'll stop boring you now, I'm just lightly toasted and thought I'd say hi.

Sorry, just realised this is in the wrong place.
