I'd say most have done both, used and not used. I think it's personal preference and based on individual goals and plans. Like you, I just got tired of dealing with it. I like to rotate my plants and running 4 air domes made moving them around more work than I wanted to do.Could we get a quick show of hands on who is running air domes, and those who are not?
I’m debating ditching them simply because it would be one less item to clean and set up. When a plant is done it would be a lot easier if I could just go dump the pot into the compost pile at the back of my property vs taking the time to dig the air dome out and clean it up. It would also be easier when I want to rotate plants or pull them out of the trays for any reason.
