I have a 6 man Apollo spa that I sold. I am going to use the slab it is on to build a place to lounge and put my bbq's and smokers. A kind of covered cooking area with an enclosed attachment for storage of my BBQ related stuff (briquettes, utensils, etc). Off of that I am going to make a hidden grow room for my own personal use (approximately 6x8 or 8x10). My question is. Will the 220 that supplied power to my spa/hot tub be sufficient to run my grow room..? There is a breaker in the garage as well as one on the back of the house for my spa.
