Deer typically take the path of least resistance so if fencing isn’t an option you could try getting some lay downs & strategically placing them to funnel them in a direction that leads away from the plants as well.
Growing outside certainly has its advantages. The closer we got to harvest last year was pretty rough on my anxiety though & that along with other life events prompted me to try my hand @ the indoor game. Whole different ballgame but I’ve enjoyed the process even though I’ve made plenty of mistakes thus far

Good luck & I’ll be following along if you plan on keeping this thread going.
