Ya, a screen with plexi or glass over the top like Don said.
I would build a hill with a drainage layer, you can buy hydro balls, or like me, use styrophome packing peanuts. Make the hill, glue screen over layer, you'll need to suck up excess water with a turkey baister. 2 inches of coconut fiber, then plantation soil(or bed-a-beast) don't buy dirt from a regular store, fertilizers in all of it, it will kill them. Don't trust it even if it's organic, and moss over that. You can buy leaf litter or live moss on line.
Plants, rinse leaves well, soak roots overnight, remove most(90%) of the dirt. Leaf shines, and fertilizers are toxic.
Plant favorites---
Phothos vine, corn plant, prayer plants, snake plant, drecanea, peace lily, bamboo, bromeliad, and orchid. Sweatpeas and African violet if you want an easy growing flower. Broms and orchid are harder to keep growing.
You can use natural wood, that'll save you allot$
Led lights are pricey, and only found on the net. But you can really see...
