Remember as a kid and having fireworks. The snake would always burn and grow and amazed us. The brick does the same thing. I put it in water and man did it grow. Is pretty cool to because if you don't need the entire brick just take a hacksaw and lightly saw off what you need. Wrap the rest in something sterile and BAMM!!!! It made growing much more intimate also because I can stand to be around my tubs without wearing a clip over my nose. Awesome product I actually just ordered 4 more before filling out this review.

Mold resistant pretty easy set up

awesome

Awesome Premium Coir Brick for bulk growing. Perfect for growing the 32oz medium jars. The product expands well with water and will last a long time. Inexpensive and naturally resists mold. Recommend 100%.

I actually do not use these in my Bulk grows, I use them in my Greenhouse Vegetable garden mixed with top soil and other items
