I have abundant attic space for an indoor grow. However to get power water and a drain is going to take a lot of work. I live in the country so my power and water is away from the house. I have a space to build a 10 x 20 grow shed out by my power and water. This will spare me some expense. Both are secure spaces but I live where temps can reach 110 in the summer. So my attic can reach 150. Any thoughts advice recommendations would be appreciated. I am fairly handy and want to do a sealed grow room as I am growing medical with access to multiple cards and caregiver recommendations thanks
