mg is full of chems , and runs hot with slow release nutes. It may grow some plants. The quality will be lower. The buds will be harsh.you guys bash mg soil . I have planted seeds in it and grow monster plants . the time released fertilizer is so light its like point .5 need to get .95 higher to get to the entire 1 so its .5.5.5 not even 1/1/1 HUGE difference . read this shit and use it before you bash it .
