Air-Pot Container
This Air-Pot can be used for seed germination and cuttings. Plants can be kept for one to two seasons before transplanting into a larger pot, or directly in the garden. These pots will accommodate a 2' to 4' plant through the vegetation and growing cycles depending upon the space available. The Air-Pot® is a recyclable, reusable plastic container that actively enhances the quality of the root systems of plants. This revolutionary approach to containerizing plants and trees produces fabulous, non-spiraling root systems that are impossible to develop in any other available container. Made of recycled HDPE in the UK, the Air-Pot® is circular in shape with a perforated sidewall. There are no flat surfaces due to the inward and outward pointed cones, which eliminates any chance of starting the spiraling process as well as dramatically increases growth rates. Air-Pot benefits: Eliminates root circling Reduces growing time in the garden Increases yields Simplifies production Minimizes the need to transplant Ensures superior performance in extremes of weather The Air-Pot is made of recycled HDPE plastic Reduces the chance for overwatering

Grodan A-OK 36/40 6/15 Starter Cubes, 1.5" x 1.5", 30 sheets of 98
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.

Grodan Pro A-OK 36/40 6/15 Starter Cubes, 1.5" x 1.5", 30 sheets of 98, Commercial
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. Note: This item is for commercial use and is packaged as bulk, without retail wrapping or labeling.
