So you received some with your sample pack too @FreakyDeekie? I hadn’t really seen anyone saying they did, hence the reason I asked.
There’s a growmau5 video that he did a side by side with the photosynthesis plus and mammoth p. The mammoth p was the winner so to speak, but the photosynthesis plus comes out a little cheaper per dose. You always have to take that stuff into consideration.
As far as applying to your current grow, I guess it would be interesting to see how you feel it works. I haven’t used either, so I can’t really speculate any more than that.
