I thought I'd chime in because I grew some ILGM seeds last season. Last summer we split a sativa mixpack with gold leaf added on with some other growers. The germination rates were kind of mixed, with chocolope having the poorest, and super lemon haze having the best. When we contacted them about the germination rates, they said they would be willing to either replace the seeds, with the caveat that there would be a delay (this was early in the pandemic). They offered us a promo code for $150 store credit that would be active two months later when their stock moved as an alternative, and we accepted.
Some time in July as the summer grow was ongoing, the store credit went to a 20-pack of girl scout cookie extreme seeds during a promo when they cost $150, but I didn't start any until early December. I have four mature(-ing) plants and a couple of seedlings that I have grown from among them so far. There is a good deal of variation between plants (height, leaf width, color, plant structure), and a number of them have been finnicky (the only plants in the tent to show light burn, for example). The one I have liked the best so far is early in its flowering period and smells candy-ish at the moment.
The super lemon haze, strawberry cough, and gold leaf were all large and vigorous outside. However, the bud from many of them was nothing special, and while I do not claim to be a professional, I have grown many times before and produced bud better than from those plants. Overall, I would say that ILGM charges relatively premium prices, is relatively easy to deal with, but I'm not thrilled with breeders/banks that are unnecessarily evasive about their genetics. Combined with the issues with consistency, I would not be in a rush to grow their stuff again. Since then, I've gone for Humboldt Seed Company through Hembra genetics for seeds.
