I found this technique on the bodhi seeds website years ago…cant find a link now. This is how they reccomend germinating their seeds.
- Soak rockwool cubes in ph 6.0 water.
- Place cubes in a tray.
- Insert seeds pointy side down. ( use tweezers)
- Tear off small pieces of rockwool and cover the hole.
- Add a dome or place in clone tent or both depending on your setup.
- Wait.
I’ve gotten 100% using this method many times.
You may need to help a seedling shed its shell or possibly dig one out of the cube but its very rare if you insert them properly.
You still need temp and humidity dialed. Im usually in the high 70s or low 80s for temp and in the high 60s low 70s for humidity until i transplant.
