My grow set up requirements

New to the site but been using it for Information and tips over the years, so here it goes with my first post.

I'm starting a grow... my flowering room will be 2.4m/1.2m/2m grow tent 8” outtake 6” intake on a fan speed controller. 2 600w hps.im looking to do ten lady’s (pineapple chunk) in either 10/15l pots 5 under each 600w hps, coco medium.

my issue is I also need a veg room for a continuous cycle, now I’m looking for suggestion on The size of tent, lighting and extraction. I don’t want anything to big just something to get those ladys started before they are moved to the flower room where they will still be veged for 2 weeks under 2x 600w MH before turned to flower. will a 1.2x1.2 and a 400w MH be enough to get them to this point and maximise yield or should I be looking at something a bit bigger for my veg room? TIA!

I used to use a 4x4 with 600w mh in winter and 315cmh in summer to feed my 8x4 perpetual flower tent.

6" fan should be plenty if you venting heat outside.

I made it all work for me, there's always time when you wish you had more room though.
