Grodan® Rock Wool 25x25x40
Product Details
Grodan A’OK plugs are designed for seed and cutting propagation prior to “blocking on” into larger growing blocks. Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
