mars is a waste compared to spiderfarmer imo. people with mars swear by them but I believe that's because they haven't upgraded yet lol. i have 2 mars blurples sitting in the same tent with a 480 quantum board and I can tell you the difference is night and day, I actually put the plants I want to grow slower or receive less light under them on purpose, such as seeds or clones! they do great for that scenario and will grow a nice nodey little veg plant! as for flower, shit starts to stretch and reach and its a very airy mess. wouldn't go blurple for flower. and for that matter your spending the same money on a spider for better diodes and a good driver, as compared to the mars with lesser items. I'm not gonna edit this I'm kinda busy, sorry for the typos
