to chill the water i just dropped iced water bottles in for a couple mins...that drops the temps quick...my roots always start out nice milky white, as they progress they turn a darkish tint, but you can still see the new milky white roots growing..a dehumidifier works good too for moisture..air pump im using one of those dual pumps from walmart like 10 buck with a tiny airstone, I did an h202 treatment one time on normajane in the beginning, and I damn near killed her, so i personally stay away, It fried the roots and I dunno like dehydrated them, they turned brittle.. the plant did not like that..oh, root rot, kinda smells...like rot..its apparent, i flushed a good week or 2 with fresh water, cleaned out the res real good also, scrubbed it..roots also dont like light, but we all know this...
