A-OK Starter Plugs are meticulously crafted to streamline the growing process, providing convenience and efficiency for both seasoned growers and beginners.
Grodan stone wool products are renowned for their consistency and reliability, ensuring uniform and predictable propagation with high success rates. The A-OK line features uniform density, firmness, and fibrous structure, facilitating both manual and mechanical processing. This uniformity also enables balanced water and nutrient distribution, fostering optimal rooting and initial crop development.
These reusable trays are built tough for long lasting durability! They are injection molded, where as most 10 x 20 trays are vacuum formed. They are four times the thickness of regular 10 x 20 trays. No need to use multiple trays to gain strength when one quad thick tray will do the trick. The tray insert has a perforated bottom for easy drainage.
