I will be using well water. I am really tapped out on money because I spent all I had building my room and furnishing it, now like an idiot, I didn't save for clones or seeds. luckily I had a person gift me a purple silver haze. it was transported in this freezing weather to me so I think I made a mistake maybe. I gave it a little shot of miracle grow to keep the roots from going into a shocked state from temp change and light change. it is really looking nice and flourishing well. now its time to give it the good stuff I think? Im building a barrel for water storage and feeding. so the water will be room temp. is that a good or bad idea. im going to post a couple of pics of the plant for you to check out. thanks
