Hi guys im Max and im new around here, i've grown few time and this is the second time i grow autos. i have a 250W HPS\MH light (its a dual). first time i grew a jack herer auto, the yield wasnt amazing (about 24g) but it was good shit. i came across this info that autos prefer blue spectrum when they veg cause red spectrum might fuck with their sex. is that true? im about to grow 4 different strains (i will elaborate if needed). should i be worried using this light? also, while at it, would you prefer starting with a 24 hours light circle or 20\4? thanks in advance. i can use all the knowledge i get!
