I’ve been using pellets for decades, and far prefer them to shavings. I even tried going back to a mix (as had been recommended by someone on C0TH) a couple years ago, which only reminded me how much I prefer pellets. I do use the TSC pellets, as that is what is available to me here.
The only time stalls are stripped is before pressure washing the barn. When starting with a stripped stall, we begin by putting down a very light layer of a product such as Stall Dry or Sweet PDZ (this is over the rubber stall mats), before adding the pellets.
My barn has 12 x 12 foot stalls, and we use about three to four bags of pellets over the mats when starting from scratch. Generally add a bag/week/stall (half bag at a time), but this could vary – for instance, if bad weather necessitates more stall time then additional bedding might be necessary. The stalls have feeders in the corners, with Nelson waterers in the diagonal corner, and I try not to have much bedding in either of those two areas, as it would be wasted there.
When necessary, half of a new bag is dumped towards one side of the stall, in a pile, and watered by a hose sprayer (not soaked), left to sit, then forked over to see how dry the pellets deeper in the pile still are. Most often, sprayed one more time, and left to sit again*. Later, the fresh pellets are spread by the forkful, concentrating the clean pellets in the areas where the horse likes to lie down.
Have only had geldings for a number of years, therefore the wet spot(s) is/are located around the mid-stall area. When cleaning a stall, I fork up these spots, apply a small amount of the Stall Dry or Sweet PDZ, let it sit for a minute, then pull some bedding from the stall sides to cover these areas.
The idea is that older bedding is used to soak up urine, while the horse can sleep on the clean, fresh stuff, and none of it is wasted in the food or water areas.
*the water amount needed is probably affected by both the humidity level and the pellets themselves; never used to need to water pellets here, but we’ve been in an extended drought for a long time and must do so now
