PHOT is a long time hold for me and I am still buying. I think it is the best of the Greens from infrastructure standpoint. Visit each one of the links at the top of information box. Spend some time on those sites. Some are still growing (no pun intended) but SG/PHOTOTRON products and the GRENER.com website. I LIKE.
I own MJNA on the medicinal side. I have some of the others as well for a "you never know" hold. But by far I am all in on PHOT and picking up more.
