Description

Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy- like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums. Grodan A'OK plugs are designed for seed and cutting propagation prior to "blocking on" into larger growing blocks. The V-shape design of the plug discourages tangling of roots between the plugs in the A'OK plug sheet. A'OK plugs come in a sheet that fits a standard 10x20 flat.

  • Exactly as expected
Not very cost effective to purchase in small quantities like this, but I didn't need more than this, so I guess I'm happy enough. Otherwise exactly what you should expect: Great rockwool, easy to use, excellent results.

  • Just what I needed for hydronic herbs.
Came in a nice intact block. Works great for my hydronic herbs. The same packets of seeds started more quickly in these, than in peat pots. I didn't actually use the gloves.

  • Quality rockwool
I have successfully cloned multiple batches in these. The size stands well on it’s own in a humidity dome. The size can also be a problem because it takes longer for the roots to grow out beyond 2”. I’m trying smaller sized cubes this round to see if I can plant faster. Clones are getting hungry in these before they’ve made long enough roots. Regardless, they work well and usually have a good success rate if used properly. ... show more
