Grodan Pro 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.
Single Sheet includes:
1 strip of 15 plugs 1.5'' x 1.5"
The finely woven stone wool in the Starter Plug provides the perfect environment for young roots.
Grodan’s products are designed to work together as a complete, professional growing system allowing cultivators to handle and process young plants at much faster rates. The 1.5” size A-OK Starter Plugs™ fit snugly into the Gro-Smart tray which, in turn, can sit comfortably inside a standard size propagation dome.
The steps for successful propagation with A-OKs are easy:
the A-OK Starter Plug with 1.5 EC nutrient solution pH adjusted to 5.5 – 6.5 with a coarse spray or submerged for up to 1 minute and let drain.
2. Take cuttings
that are no more than 14 days old, apply rooting solution to cut only and insert stem ½ inches into the saturated A-OK.If growing from seed, place one seed using clean tools into the perfectly sized hole of the saturated A-OK.Monitor the wet weight. Once the wet weight reaches 50% apply an irrigation with a nutrient solution of 1.5 EC and 5.5 pH. Drain excess to prevent mould, algae a
nd disease.Allow your seedlings and cuttings adequate time to fully exploit all the stone wool in the A-OK Starter Plug™ before transplanting.
When it comes to transplant time, moving your young plants on to the next stage couldn’t be easier! Grodan Gro-Blocks come prefabricated with the perfect sized hole to accommodate our A-OK Starter Plugs™. Soak the A-OK Starter Plug™ and Gro-Block in the same strength nutrient solution — typically 1.5 EC at pH 5.5. Once the A-OK Starter Plug is well rooted with strong white roots emerging from the plug, transplant the young plant into the hole at the top of the Gro-Block.
Grodan takes the guesswork out of propagation, allowing you to generate batch after batch of consistent, healthy, and vigorous young plants.
