    Great size and quality. Already used it to make a good batch of tea and it seems to have allowed a good saturation.

    400 mesh bag,

    Posted by Rolando Rodriguez on 18th Nov 2019

    I used the 400 mesh to brew castings tea and noticed the difference in how much cleaner the tea tank was at the end when compared to how if it was with the 40 mesh bags. The only suggestion I have is to try to sew a piece of sturdy cloth on all 4 sides and to add a zipper. A ring to attach a carabiner would also be nice.

    brewed compost in this bag for 24 hours and the tea did not clog my backpack or tractor mounted sprayer

    It was nice to clog the spray nozzle of 2 different sprayers after brewing and straining the tea through these bags

    Compost Tea 400 Micron Mesh Strainer

    Posted by Mark on 12th May 2015

    It can be used as a tea bag but since I make 6 5 gallon buckets of tea a week, I just use it as a strainer. I use heavy gauge wire formed in a circle to hold it open over a empty 5 gallon bucket and pour the un-strained tea through it. When I'm finished, I spray it off with the hose. I have used it several times and it is holding up well and filters better than the paint strainers I used before.

    Perfect Bag for brewing compost tea

    Posted by Unknown on 27th Apr 2015

    The service and shipping was excellent. The quality of this bag is excellent, and although reasonably priced, the quality and 400 micron mesh makes it the perfect brew bag....
