I think your logic is pretty sound with the idea that just because something is organic doesn't mean it isn't harmful for your plant. I'm not in favor of spraying bud at all with anything no matter what and will resort to meticulous spraying of the foliage with a direct stream and not a mist if there is infestation and I absolutely have to spray.
Your future plan sounds really good with growing some stuff alongside the cannabis. You mention cannabis not being hard to grow, but actually I feel like it is a pretty difficult plant to grow unless you have a super green thumb and it just comes very naturally, and for you I think it does because your plants look very healthy :)
I can probably harvest these in 2-3 weeks (?)
Do you have a day count on the current flowering time? Depending on the genetics they could have a longer flowering time.
I see no brown pistil coverage yet, and bud formation looks early. I do not think these will be ready in 2-3 weeks, maybe 4-6.
Speeding up drying is generally not a good practice with the process, but if mold is a concern then adding some fans to your dry space is a good idea, and even some direct airflow on your buds. This is not recognized as good because it can make the smoke a little harsher.
With the curing usually once the bud is dry it should be pretty worry free in glass jars. Try to burp them in low humidity environments if possible to release excess moisture and CO2 emissions.
Macro lens is great for the blog as well as trichome inspection. I would definitely get one. I lost mine during a move and still trying to find the darn thing. Probably going to just buy another one...
Looking really good, keep up the great work.
