According to the website - you don't need to wet straw pellets as they break down much easier than wood pellets horsebedding.uk.com/straw-pel...questions.html To be fair - I never used to be bothered to wet the LWP either, I found they were only crunchy for one night and after the horses walking on them, they went soft quickly.
This is the bed after a night. Notice the mess he makes!
From the previous pic of the dirty bed, this was the muck I took out from it.
I'm finding them comparable to LWP but the bed kicks up a little dust when mucking out. I never used to wet LWP at all and there was no dust from them. I am actually afraid of the dust from the straw pellets as straw sets of my asthma quite badly.
Time will tell, but my preference remains with LWP at the moment.
