I check the soil in my GH plants regularly. Probably more than I check when the plants are outside. They just tend to dry out less with the high humidity inside. Also some of my plants like my plumeria, some Elephant Ears, and gingers will receive no water at all so as to not risk rot as they go dormant. I'd have to say the GH is high maintenance when it comes to watering, misting, and monitoring humidity etc. But it's worth it to me to over winter my Pretties so I can have bigger.. lush plants in the spring.
