Buds your cab plant looks beautifull
Are you growing the seedling the entire life on the window sill or are you going to trow her in tbe cab when the other finishes?:
Wonderful plants mate, keep up the good work.
That mystery plant looks like basil to me.
I was thinking to write you "don't give too much humidity and temperature gap".
Sorry for your lost.
I had lost 5 Lady Cane seedling 2 years ago by dumping off.
You have to bury a seedling only with DRY soil
