Rockwool Plug Trays for Clones and Germinating
These rockwool plug trays are perfect for rooting cannabis cuttings; they’re super airy and allow roots to breathe perfectly. If your plugs are too humid you may end up accidentally rotting your plants’ roots, but if you do it right you’re guaranteed amazing results.
Learn How to Work with Rockwool Plug Trays
One of the first things that you’ll need to do when growing using rockwool is adjusting its pH to 5.5-5.8, which is what your plants need to root successfully. Once you’ve wet them you’ll need to squeeze them to get rid of any excess water – do NOT squeeze them, you’ll need to drain them by shaking them until no more water comes out.
Next, plant your seeds or clones and use these rockwool cubes as their rooting medium for the next few days – once they’ve rooted it’ll be time to transplant to a slab or your preferred substrate.
