REDROCK: Cylindrical Plugs Offer Benefits
RedRock Wool plugs are designed for mitigation of density changes in grow media, rapid transplanting, and improved plant development rates. Plugs fit perfectly into blocks to avoid compaction and air gaps around the root zone of young clones and seedlings. Predrilled holes rather than slits better hug and support infant crops during their first stage of development. Cylindrical plugs eliminate corners for increased uniformity and less overall deviation.
Growers pay a premium for high-grade Stonewool and maximum uniformity, don’t let your plugs interrupt perfection.
- Accurate and hassle-free plant placement.
- Non-taper cylindrical plug shape mitigates unwanted density changes and air gaps.
- Greater plant stability and early stage rooting
Other Stonewool Companies
- Square plugs lead to time consuming transplants and substantial density changes.
- High risk of breakage due to decreased overall stability and inconsistent material/plant bonding.
SELECT GROW MEDIA FOR COMMERCIAL USE IN PLANT NURSERIES
It is common to find propagators moving fresh cuttings into plugs for the initial stage of development. Once rooted plants are transplanted into starter blocks, grow blocks, and then placed on top of stonewool grow slabs to extend root zone development and access to water and nutrients. Selecting the correct substrate for your crop depends on many variables such as size, duration, density, and more..

REDROCK STONEWOOL’S USER GUIDE
- RedRock starter plugs are ultra-durable and made from premium material, but they should still be handled with care; Always keep mineral wool dry until use.
- Saturate plugs by spraying with nutrient solution or submerging them for about thirty seconds. Squeeze gently or let them drain for a few seconds before placing them in a propagation tray.
- Carefully insert your seeds or clones ¾-inch to 1-inch deep into the plugs’ pre-drilled holes.
- Continue to water whenever your plugs are about halfway dry – this schedule best mimics the natural “dry-back” that plant roots experience in natural soil.
- Once your plants are ready for transplant, saturate the plugs completely with nutrient solution, squeeze gently or wait for some moisture to drain out, then simply insert them into the RedRock grow blocks’ precut holes.
