Dunking isn’t really practical once plants get bigger. Also I have PTSD from dunking from years past, when I dunked some seedlings in a strong solution of neem/silica and killed like half of them

@LegsMahoney nice creative thinking! Mini-tent for spraying purposes. Much easier to assemble/disassemble than my unwieldy tarp-thing. Love this idea, maybe I’ll repurpose a pop-up tent from my boys. But if they find out…
