I’ve used them a fair bit now over a couple years, here’s my take.
I think they work more or less as promised, I’ve only tried one harvest where I used them exclusively without burping but it worked okay. I have used a them more post cure for long term storage. They are easy to use, and not having tonnes of heavy breakable jars around is a plus.
After using them, a couple things make them not right for me.
First, I’m finding the “zipper†fails pretty quickly on the bags making them pretty useless, and I’m not into the plastic waste or buying more all the time.
Second, they say they hold the flower at 55-62% for me this is always at the 55% end and I want my long term storage at 62%. 55% is a nice smoke but it’s not hard to dry it a bit more it’s hard to rehydrate flower. Adding to this point the old trick of spritzing some water in the container to add moisture like we do on the lid of a glass jar doesn’t work, as the bag just lets it out so your stuck at whatever it wants. I don’t like a bag telling me how dry my weed should be 😆
