Up potting has too much benefit for the root system. I recommend putting them each in a small pot and then up-potting them after a week or so.
Good luck!
If they're autoflowers, put them straight into the 10L pot and don't transplant them ever... if they're photoperiods, go with the small pot and transplant when you get a nice root ball...
Good luck!
Se puoi metterli in jiffy e meglio (dischetti di torba)...oppure pianta direttamente in vaso predefinitivo! Qualsiasi cosa puoi scrivermi anche in privato no5ln ce problema!
