Hello,
I live in an apartment in Los Angeles, CA (zone 10b).
I have 2 Delonix Regia (aka flame tree) seedlings and 2 Jacaranda Mimosifolia (aka Black Poui) seedling, all from seeds sowed on 9/22/20, and grown in a grow tent under a grow light:
As you can see in the pics above, roots have started coming out of the pots... I thus think it's time to repot them.
Note: the better looking Flame Tree and the 2 Black Poui are in biodegradable pots, while the other flame tree is not.
I'm thinking of "repotting" these 4 seedlings, each into their own gallon pot, but have a few questions prior to do so:
- Would it be safe to basically "plant" the biodegradable pots into the aforementioned gallon pots?
- What kind of soil would you recommend?
- 100% pumice?
- Mix of Pumice, Lava, Calcined Clay and Pine Bark?
- Regular potting soil?
- Something else altogether?
Any suggestions would be greatly appreciated!
