  • You get what's advertised - will buy again
Size: 20.0 lbs
The product came on time and delivery was prompt. The packaging was resealable which was very important to me. It was definitely ultra fine which made it very easy to mix in hot water to dissolve for use in my CVG substrate. I am totally satisfied with my purchase and will probably be reordering when needed. I use approximately one cup of gypsum with 1250 G of coco coir and 2 qts of vermiculite with 8 qts of water for great field conditions. ... show more

This ultra-fine lab grade gypsum is fantastic! I use it for a variety of crafting projects, including making molds and casts. The fine texture makes it easy to mix and pour, and it sets quickly to create detailed and precise casts. The quality is top-notch, and the gypsum is very smooth, resulting in a flawless finish. Whether you're a professional or a hobbyist, this gypsum is a great choice for your crafting needs! ... show more
