1/3 of the tub was like 5.3 inches so I figured I could slide the tub a little forward but 4" tape might be better. I already have a VE200 and the tape and connector set is already over 100 bucks so I'd prefer not to have to buy another thermostat lol. Now that I think about it I should be fine just putting 16" strips on each shelf and the THG website says you can run 50' of 3-4" tape per thermostat so I would assume I'm fine. I really like to overthink things and make them more complicated than they are haha
