I believe the seeds are immature, with the 2nd seed I just went back to what I know works. The 1st plant fried as if I poured a whole bottle of nutes on it, left it in the sun, didn't water...… BioBizz wouldn't do this, however I went back to what works, contrary to what you may read around here, Fox Farm soils are excellent and have worked for us for YEARS, from single plants grown on a desk to some large scale growing, indoors and outdoors, It is affordable and easily available. You simply have to understand how to grow in soil. I never seem to buy these elusive 'bad batches' that seem to be going around. I don't PH a thing and NEVER have with this soil. I to this day don't even own a PH probe. Nobody PH's the soil on these plants when they grow in the wild in nature, we try to replicate how they grow in the wild using Fox Farm soils as a base. With that said a PH probe is a great idea and more power to those that use them, for me, the biology in the soil buffers and maintains the PH but more importantly gives the plant WHAT it wants WHEN it wants. I will go back to using BioBizz and Megacrop as a feed with a different strain at some point in the future...… Maybe, is it possible, that I scored that elusive bad batch of BioBizz soil the 1st time I try it?????? Doubtful....I love Mephisto but suspect the seeds found in this pack. As even the plant that is now in flower had a very shaky beginning though it didn't fry like the 1st.
