Great for Propagation! In horticultural applications, perlite is used throughout the world as a component of soilless growing mixes where it provides aeration and optimum moisture retention for superior plant growth. For rooting cuttings, 100% perlite is used. Studies have shown that outstanding yields are achieved with perlite hydroponic systems. Other benefits of horticultural perlite are its neutral pH and the fact that it is sterile and weed-free. In addition, its light weight makes it ideal for use in container growing. Other horticultural applications for perlite are as a carrier for fertilizer, herbicides and pesticides and for pelletizing seed. Horticultural perlite is as useful to the home gardener as it is to the commercial grower. It is used with equal success in greenhouse growing, landscaping applications and in the home in house plants. Each white granule is comprised of tiny closed air cells or bubbles which account for the light weight, reflectivity, adsorptive capability, and superior insulating qualities. The surface of each granule is covered with tiny cavities providing a large surface area capable of retaining water, air, and nutrients. This physical structure makes Horticultural Perlite an ideal growing medium, providing optimum air-water relationships for efficient plant growth.

Love product..mixes with other products to.make seed starting mix...
Trays are nice and sturdy … will definitely hold up for a number of years if not abused
Great everything was great
Seem to be holding up well so far, I bought 30 and filled them all up and have moved them several times with no issues. Will be buying more.
The product came quickly, the trays work great together and there have been no issues.
Great product for the price. Good quality and will last a few years. The best place I've found to buy pots.
This test was easy and convenient. The results came back quickly. I found out I was very low in nitrogen. Glad I found that out before I planted tomatoes and peppers.
My neighbor saw how great my fabric was instead of the stuff from big box stores. He wanted me to order for him and that is this order. He is excited to get it in.
Work great for what we needed. Nice quality trays!
Just what I would expect for cardboard beer boxes. Get the job done. Will buy again.
