GroFast 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, we are unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. GroFast has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth.
GroFast 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 GroFast cubes can also be transplanted into more traditional planters and growing mediums.
The renewed plugs result in a maximum number of useable and homogeneous seedlings. Both form and strength have been greatly improved for good machine and manual processing. Whether sowing or transplanting, a new plug is the solution to achieving a homogeneous sowing result of using GRoFast.
Advantages of using GroFast :
- Improved homogeneity
- Optimum robustness and flexibility
- Ideal air/water balance
- Consistent shape of the seed hole
- Identically shaped plugs
- Root development through the entire plug
GroFast 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 plug sheet.
