Try to crumble it up as finely as you can. Mine dried up enough during the decarboxylyzation(sp?) process that it almost powdered with a bit of effort, but wasnt as easy to powder as flowers. I had bunch of miniscule balls that didnt attain powdered consistency, but my wrists were too tired from picking at a quarter ounce of hash chunks to continue (carpal tunnel). It couldnt have affected the potency too much though because the butter was ridiculous (I had one of those fabled weed overdoses, lasted close to 2 days and I didnt even want to get high again after for a day or two).
We all hate the tedious "eat a little, wait an hour" bit, but I would do it the first day until you understand the potency of your hash. I stay high all day everyday off either wax, hash, or the best flowers, but it sure as hell didnt save me from getting unpleasantly owned by the hash edible. I dont know how you roll but Id say treat the hash edibles at a 5:1 potency ratio versus traditional edibles, thats roughly where I had to adjust my intake afterwards.
