Thanks for the question. And Greetings from Ukraine again. I think that the rains is usefull for good growings. You can use rain for sad look of your Plant. I'm use for that purpose Spray-Bottle, You can unscrew the cap little and push it. Drops will hit the leafs and light will enter to the hidden zones. But Better to do this in the washbowl i think (you can make holes in it with help of hot prod) . For Economy of water at first, and you didn't need to hit you Plants too often.
