Gonna have two of these in the next run. I'll have to relearn how to water pots properly after running Rain Science Bags for a couple years now. I do think the layer of volcanic fluff I put on top these two three gallon pots has helped with the watering on those small pots.Yes very similar to RS I never had a RS bag in my hands but my buddy has both and says they are very similar but the coda bags have a tighter wave.. I am almost positive it is a pvc material they hold up extremely well and super easy to clean I have some bags that have had a few grows through them and they clean up like new.. Now the TLS 2.0 bags are a canvas side with mesh bottoms they are really nice for living soil helps keeps the sides from drying out and the soil alive
That really only lends itself to a non-organic grow though.
