Why im signed in,i just wanna ask you uk growers a quick question, how far are you keeping your 400w - 600w hps lights or light off the top of your canopy an how dense are your final buds,the reason why i ask is,i used to use a 400w hps an tryed to keep the light around a 1ft off the the canopy the buds were all ways soild dense flowers now i use a 600w i try an do the same with a good airflow moving over the buld,i just think i might be a bit close,recently 3 of my girls grew right in to the shade of the light,they were ok but i never want them that close again, im struggling with the canopy cause like a tit thought I'd do a few strains an they all different heights,they doing me head all the arseing round moving them about, never again will i do this many different strains....
