Watering With Humidity Trays

[DesignerofBeauty]

Hello Everyone,

I have a question regarding humidity trays and watering orchids. I grow my orchids under LED lights. I just purchased a set of nesting plant benches to house my orchids. My plants are on the opposite end of the house from kitchen. I use RO water that I store in pitchers to water my plants. Between grabbing pitchers and bringing two plants a time to the sink, it becomes time consuming (I have 40+ potted plants and 5 terrariums filled with micros and minis). As a result, my potted plants aren't watered as frequently as I should.

I was considering an option to help make the watering process simple. I could purchase humidity trays and fill them with LECA or some other wicking material. I could mist or water the plants carefully - until water starts dripping into the humidity tray. Thus preventing me from walking back and forth to the kitchen.

My concern is that if a plant is diseased is there a higher chance that other plants on the same humidity tray would get infected?

Thanks for your help!
