A-Ok Starter Plugs are for starting seeds and rooting of cuttings prior to plugging into the larger Gro-Blocks. A-Ok plugs come labeled with instructions in a shrink-wrapped sheet that fits standard 10x20 tray (flat). Note: Item #713020 is supplied without shrink wrap.
Gro-Blocks are similar to 'plant container'. Need a 3" pot? Then choose a 3" Gro-Block. Small plants can be fully grown in larger Gro-Blocks. Holes are perfect size for any 1.5" starter plug. Come in packs labeled with instructions.
Mini-Blocks sit in a tray (flat) without support for easy starting of seeds and cuttings. These Mini-Blocks are individually wrapped in white plastic to minimize algae growth. Remove wrapping and transplant into any loose media such as Growcubes or coconut fiber or leave wrapping on and set on top of a larger Gro-Block. Packed in easy to tear away strips, labeled with instructions.
1.5" - 15 blocks per strip/50 strips per case 2" - 12 blocks per strip/60 strips per case
Granulated rockwool works great on its own or mixed with other loose media such as expanded clay rocks or coconut fiber. If planting in containers outdoors, Water Absorbent Granulate is the best medium of choice.
Gro-Slabs provide the final stage for growing a spectacularly large plant. Transplant your Gro-Block plant onto a slab just like professional growers. They come in clearly marked biodegradable UV resistant sleeves for comfortable handling and algae prevention.
Expert vertical fibers for faster drainage; best for hobbyists

Growcubes are small, loose 1/2" cubes of stonewool. Advantages are better aeration, maximum drainage so that you can hardly ever over-water your plant, easy mixing with other loose media (such as expanded clay rocks or coconut fiber), lightweight and much cleaner than pot-based media. The properties of Growcubes make it like a 50/50 mix of absorbent to repellant stonewool.
Macro Plugs have a slit that allows easy insertion of a cutting. These loose round plugs fit perfectly into the Gro-Block hole. For best results with these Macro Plugs, always insert them into a tray with individual cells. The individual cell will make sure that the plug stays closed around the stem of your cutting.
