10 random bags, there's no telling what size or filter they'll be, or if they're taller/shorter/wider/skinnier than they should be, but they survived QC just like every other unicorn and some even come with injection ports!

Good, so far?

I received these bags quickly, and in perfect order, but have not used these bags yet. Judging by all the good word over the net, I will not be disappointed. I would bet I will be ordering again in the future!

Jars No More!

I’ve been using the 3T grain bags exclusively for six months now, and the only downside is I now have no use for allll the jars I’ve accumulated over the years. Time to open a canning business I suppose! 🦄

XLS-A keeps the Trich away!

After having constant issues with Trich in my monos I decided to start living the bag lyfe with the help of these XLS-A bags. After seeing the giant minimum order sizes direct from Unicorn, I decided to give Pegasus a try so I could dip my toes in without being out a huge amount of money. I placed an order for 30 bags from Pegasus and they were to my door less than a week later. The awesome slap hidden in the bottom of the shipping box was a nice surprise as well. I messed up and bought the wrong type of bags initially, but after sending an email to Garret, he was able to get them switched for the right ones before they shipped out.

These XLS-A bags have filter patches that are just the right size to provide enough fresh air exchange for bag fruiting while keeping the green **** out. They easily survived 2 and a half hours of pressure sterilization after adding my sub. After adding my colonized grain to my sterilized sub and sealing the bags with my impulse sealer, I’m happy to report my first successful harvests from these bags with no contam issues. Let’s go Pegasus Bags!
