Hello man, I normally do as you do, there was no moss…
And I left it open to be able to observe the development of the roots, I had already done this with males in the 2020/21 guerrillas, with success.
@ELG, this should work as long as the humidity is kept high.
In guerrilla 2020/21 some plants put roots above the ground, about 50cm!! Too much moisture.
take a look at Agroecological guerrilla, in search of the True Brazilian Sativa
