LPintoanswered grow question 21d ago Good morning...
I didn't quite understand this technique/method...
It seems a bit risky for the plant...
If I understood the method, it will kill the pests with the heat and smoke from the branches and cardboard, which means that if it kills the pests, it will also harm the plant...
In my opinion, it seems like a somewhat aggressive process, but your concept is similar to chemotherapy; it will kill the pests and it will kill good parts of the plant…
