Right i think ive got it now lol.Thanks zandor.ive grew from seed this time as thought i would try a change of strain so i just trained them through veg until they were sexed they vegged for 5 weeks and when they went in to 12/12 and i started threading the screen it didnt look as if they were going to fill out under it but after 5 days they have started to fill out nicely , they are under 1000 watts hps and the screen is 6ft by 5ft and im a bit paranoid that the 1000 watts is not sufficient i have read that it covers 7ft by 7ft but we all know how you can get when you get into the lunems territory lol we end up going mad , adding and adding.Dont want to go there.Heres some pics of them in veg.thanks a lot the Postman.
P.S adding lights i mean not lumens.
