Polishpollack, I had him spray misting them untill they regrew roots to replace the ones he cut off because they were transpiring faster than they could take up water, since misting raises humidity which slows down transpiration. As far as houseplants go, unless we're talking cactus, succulent or hairy leafed plants, they all should be spray misted. Plants like higher humidity than you can achieve in your house with causing mildew growth on everything.
---- When plants are grouped together, the transpiration process naturally raises the surrounding humidity. Paintreat, once your plants resume growth, this will indicate they've grown more roots. When that happens, stop spray misting but if they seem to need it, mist occasionally. The humidifier shouldn't be needed at this point. Keep in mind that cutting off roots was drastic, don't do that again. I think you'd be better off growing in a soiless mix, I like 3 pts milled spaghnum to 1 pt perlite with some organics mixed in, but some people omit the organics & rely on applying nutrients. But untill they've put out quite a bit of new growth, I think transplanting now could put them into transplant shock. Post new pics. Some close & some wide shots.
