hahaha i just installed the old one and that thing is GHETTO hahaha
this one is much better, even though i messsed with it for 2 seconds and got tired of it. I don't freaking know how much of nitrogen, "P", or calcium (K?) i need in my plants, and what the perfect ratio is. I have no idea what the difference is between grow lights, and i don't know how to change the pH.... u hafta know way more then i'm willing to research in order to grow some fake plants... unless u guys have some advice so i dont' hafta serach all over google and these forums for good nutrient ratios and what's the best growlight etc etc
