  1. I would like to buy 100 to 200 seeds for my commercial grow. Do y’all send the paperwork with each strings solar commercial Grove can keep up with all their paperwork? And if a person bought a hundred seeds could you split them up into four different strains?


  3. I purchased 13 auto pounder and 13 gorilla glue seeds. 11 of the 13 auto pounders germinated and are growing great and are almost ready for harvest. Only 3 of the 13 gorilla glue seeds germinated although a very poor percentage germinated the 3 that did are looking great. both strains were planted 7/29/20 in 15 gallon pots outdoor using organic living soil.

  4. I wonder if we crossed it with kudzu would it grow all over and have vines with big buds hanging off?? Let’s do that
