Tower Garden Starter Plugs

Tower Garden Rockwool Starter Plugs

Rockwool Starter Plugs for Tower Gardens & Hydroponic Systems

These rockwool starter plugs are designed for starting seedlings and rooting stem cuttings before moving to a larger hydroponics system such as the Tower Gardem, NFT system, etc. 

The finely woven stone wool in the Starter Plug provides the perfect environment for young roots in hydroponics systems like the Tower Garden.

We offer 3 different sizes and types of starter plugs for tower gardens & hydroponic systems.

• GRODAN plugs have excellent uniformity, strength and shape that provides the perfect basis for optimum germination and uniform seedling results.

• The uniformity and reliability of GRODAN plugs provide a solid basis for automatic or manual processing, uniform germination and a crop that can be transplanted successfully.

• GRODAN plugs have a uniform density, firmness and fibrous structure. This means that distribution of water, nutrients and pH-value is also uniform, which has a beneficial effect on germination results.

The steps for successful propagation with Tower Garden Starter Plugs is easy:

1. Saturate
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.

3. Transplant
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.
