rockwool cubes question

Would it make any kind of sense to use rockwool plugs and then plant them in soil? I know they're used in hydroponics, but do some ppl use them to germinate first? Seems like with the heat mat/humidity dome combo you can control it better, but do the plugs biodegrade over time or would it affect the roots in any way? Just wondering.

I personally would not use rockwool with soil.

Yes you can use either rock-wool or peat plugs, we prefer the rock-wool

The rock-wool does not biodegrade, not sure if the peat plugs do or not

I would sprout them first, then put them into the soil they are to be grown in. Water accordingly.

well, if your cloning you can just put the clone, RW right into the soil the roots will grow through.

Once the roots begin to sprout through the bottom of Rockwool plugs, it's time to transplant them. You can put them into soil, or whatever medium. Adjust the PH of your water to 6.2(eventually you can work your way up to 6.8, or just stick between 6.2-6.8...) after transplanting into soil. If you're using larger sized pots, it may take a couple days for them to adjust to the larger/new environment and start new growth and be careful as well not to over water the first week or so... It's easy to do. You just need enough water to moisten the plug and immediate surrounding soil, approximately 4-6" round.
