No need for pots, just cut and pop your rooted clones or seedlings right in. Amazing water and air retention, and roots can have an extremely easy time uptaking water and nutrients. Only a fraction of root mass is required to grow the same size plant as in soil, dedicating far less energy to root production and much more into fruit and bud production.
Shipping is a bit expensive for this item due to its shape. Check out our 5-slab multi pack for much better rate. Almost same shipping cost for 5 times the rockwool!
