Millet,
The seeds are germinated in zip locked packets in slightly moist  perlite at 30C. After root appearence they are transfered on the surface of substrate in covered pots.


Very interesting thread thank you for sharing your process. I'm going to have to try the bagged perlite trick as well as putting the bottles over the pots for extra humidity. Have you noticed the humidity makes a big difference in your seedlings? Are you still using this approach? Thanks again

Yes, it is definitely working to force non-stop grow of young seedlings.
Also,high humidity prevents red mite infestation.

Those are looking good and healthy!

One of those grapes in the background look to have leaves like some of the American species. What variety is that?

You have a good eye.
It is Frontenac, hybride of V.riparia and  Landot noir. Completely resistant to phylloxera and fungal diseases here.
Best regards,

Very impressive size of the seedlings Ilya.
Your raising method with germination, freeze test ( selection)
and transplanting inground seems very effective.
My Chandler x Bloomsweet lack far behind yours though same age concerning size,
but one total winter inground for one year old seedlings
seem to much for the young roots.
My Yuzmelo x Bloomsweet has trespassed them by growth, but they
havent yet selected by freeze test.
Was your leave taste test good ?
