GROW!T Perlite is a versatile and inert soil amendment and soilless medium. Use it to aerate soil in container gardening, for germination and propagation of seedlings, for propagation of cuttings, and as a hydroponic medium. Hydrofarm searched globally and went to great lengths to find a source of top-quality perlite, and succeeded-and what we found is offered in the GROW!T line of perlite products. Multiple grades available: #2 Perlite (1/16" - 5/8" granules), #3 Perlite (1/8" - 5/8" granules), #4 Perlite (1/3" - 3/4" granules), and #8 Perlite (3/4"-1 1/3" granules).
This product is used for cultivars that are very sensitive to over watering, and that require high aeration for adequate propagation. This perlite can be used as its own media, or mixed with you choice of media (soil, coco, etc...). Tropical plants and orchids love these large perlite pieces!
