@Mañ'O'Green I did not heat seal. I do not grow on a super large scale, but I would just use the oz bags. Leave 6 bags closed while I used one. I think maybe if I was going to store more for a long time I might switch back. But since my bud is smoked before that time, I am not getting the best use of them. I probably should not be opening and closing them to smoke from. How are you heat sealing them? Do you use a machine?
