Where do you source your rice hulls from smidge?
It's easier to get in bulk in my neck of the woods than perlite and greener being that Arkansas' rice paddies are in the NE part of the state and a 2-3 hour drive from my part of KY. All the nurseries/horticultural supply places in my area carry 7 cubic ft compressed bales stacked all around on pallets for $18 each, vs $22 for 4 cubic ft of Sunshine coarse perlite which may or may not be in stock.
I really dig that Sunshine brand chunky perlite, but man the rice hulls don't float to the top and seem to hold moisture longer for me and I will be fully transitioned indoors at the end of my current grow. If you can source it easier or similar to perlite I'd recommend it.
BTW, aloe and loose, desert soil loving plants that I've transitioned to the hulls so far seem to love a 50/25/25 mix of hulls/peat or some other humus/EWC or compost and it makes it easy to soak the shit out of them without worrying about water log. Good shit!
