Will tightvacs be good enough for my situation?

ha....been a while since I've been here, use to lurk these forums on a daily basis.......Anyway,does anyone have any experience with tighgtvacs at all? I don't grow, I still buy off the street but it's still pretty dank. I need to keep my buds fresh for like a month or 2, possibly 3 until I can start smoking again, so I went to my headshop and picked up like $30 worth of tightvacs since it was the only thing they had. Can anyone comment on whether these are reliable enough for that amount of time? I'm just really, REALLY trying to avoid having dried out bud when I'm ready to dig into them. Thanks......

Is freezing an option? Thats best for months+

Na, that's not really option as I still live with my parents. I probably would try that though if I could. If I really have to I'll go back out and try to hunt down some Ball Mason Jars but I mean like I said, I just bought all these tightvacs so it would be somewhat of a waste. There's not really too much online about them and what I have found kind of seems split down the middle.....some say they're fine others say they're not and other reviews are in regards to food not weed......I mean my headshop people said they were ok (Artifax if anyone is familiar with them) but I wanted see if anyone has actually used them first hand or just atleast what some growers thought about them in general.....

one more bump.....
