“Amazing, I now only grow fast and vast or green crack autos. My yield with the fast and vast is bar none. I'm currently using 100% soil less mix (perlite and perlite only) My plant is currently 4ft 6in at day 49 and its being grown with two small Mars Hydro 300's. The fast and vast genetics by heavyweight seeds is beyond forgiving in my opinion. I only have a few grows under my belt and I've done some stupid sh#$. These plants have seen temps over 90 deg. , humidity over 80%, grossly overwatered (that is why I switched to perlite, I cant stop messing with things), bugs, ect, and if you walked into my room and looked at her you would never know it, she looks and smells absolutely beautiful. Germinate and harvest correctly and you cant go wrong with these genetics.”
