how big is your grow roomI want to know how to place a 400w hps and a 600w hps in a flower room sounds dumb but Yer I don't know weather to go side by side like long ways or short way btw they are cool tubes
Thanks
you also got to remember. 600 will give off a bigger area cover of light than the 400 what I would do is hang the 600 and see were it starts to fade off on the floor. then hang the 400 and adjust as needed to give even coverage. . bear in mind plants under the 600 will get more direct light and lumin than those under the 400 .. my opinionI want to know how to place a 400w hps and a 600w hps in a flower room sounds dumb but Yer I don't know weather to go side by side like long ways or short way btw they are cool tubes
Thanks
