I've made several orders with GP. Everything arrived but there were issues.
My credit card info (along with several other buyers) was compromised. I had to deal with fraudulent charges and replace my card. It was total PITA updating multiple creditors for my autopayments.
My S1s were bunk/hemp but Gu replaced them when the issue was brought to the forefront.
And most recently Gu decided to go into business with someone who heavily trolled him for months. The guy even recorded himself taking a hot piss all over his plants to get back at GU and now he's done a complete 180 and sings GP praises because they carry his seeds. Not to mention the untold amount of fake shill accounts created because you can only find so many reputable members to give free cuts and seeds to in order to build credibility.
I will say, it was a somewhat smart move on GUs part because it put and end to the trolling but it cost him customers in the end. I suppose when you market to the novice grower its OK to lose a few. *shrug*
There's a lot more I could comment on but wont. This is just my honest experience with GP and everything I've stated can be found in the GP thread.
I have no problem with GU. I liked the plants I grew and Gu always treated me with respect, but yeah...no thanks.
The seed market is saturated right now with incredible genetics. Theres no reason to support that kind of nonsense.
