Can I substitute crushed oyster shells for gypsum?
    #22125152 - 08/22/15 12:02 AM (8 years, 5 months ago)

Im currentlt hydrating some coir/vermiculite and gywpsum for a few monotubs Im about to spawn.  But, I opened a box of what was supposed to be gypsum that I recently purchased, but there must have been a mixup at the store.  I'm almost positive what was in the box was crushed oyster shells due to the chunky appearance of what look like sea shells and a smell that is a bit different from gypsum.  Can I use it in place of gypsum, or should I wait until tomorrow to return it?

You can use oyster shell. It isn't as fast acting. it will not hurt your mix. I almost never use gypsum etc with coir. You would be good to go either way.

Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.

Thanks, guys!  I had enough gypsum for 2 tubs, but I ran out before I could add any to the third tub, and that's when I noticed that the contents of the box I just opened didn't look anything like gypsum.  I just decided to mix all of the bulk for the three tubs together, so the remaining gypsum would get distributed evenly throughout.  I think I'll be fine.

Yeah. Now you can compare them both. Good luck
