How do I go from rockwool to a soil mix?

Rockwool minicubes provide the user with the convenience of being able to transplant rooted clones and seedling starts directly into soil with little or no transplant shock.

The minicube is simply planted into the soil, as deep as just below the first node (clones), or as high as just below the cotyledons (seedlings).

Be cautious with watering the first few days to avoid damping off.

Rockwool minicubes are the 1-1/2 inch square cubes, available wrapped on four sides with poly plastic which provides a handy place to write clone id numbers or dates. The plastic is removed just before transplanting them to soil or hydro. Grodan also makes unwrapped one inch cubes which are tapered to fit into divider trays.

Larger sizes of rockwool cubes can be transplanted to soil, but it's not recommended.

Ideally you should start your seeds at about 70-78F. Once you have sprouted your seed Seedlings do best at 68ºF and 77ºF (20ºC and 25ºC). Humidity between 50-75% would be ideal for young seedlings.

like i said i germinate in a glass wrap toilet paper around inside add water drop in seed between glass and toilet paper
but not into the water .. the paper wickes it up ..make sure seed is in contact with paper n glass..

easy to pull out after it pops for a day or two..

into rockwool cube .. take steak knife cut one side of the cube top to bottom into the centre!
slide the new seedling root and bit of stem into cube slit pulled open a bit .. cube should be soake in
your fert soln.. for babies.. ..

here now we take cube n seedling and put in beer cup full of ( medium hp pro mix for me could be top soil )

cube get pack in loosely at the top but covered .. u never going to touch rock wool again ..

just transplant beer cup 2 - 4 weeks , then i go right into the 7 gallons nexts.. skip the middle transplant .. but you
got to watch watering very closely cause no root ball yet for 2 3 weeks depending on your medium.. atleast 4 5 times a day you got to inspect for dehydration happens very fast here.. water asap if there are..

cheers..

you can transfer the whole thing to soil, roots and all, when you get roots growing out the sides of the cube. i always left the germination cube on. pulling it off would have destroyed most of the roots.
