Our preferred method of providing higher humidity in ambient conditions is putting your plant(s) in a propagation bin. This can be any confined container where the plant is still able to receive light from a source outside of the bin. Although we use large plastic storage bins, you can also use repurposed food containers, plastic cups taped together, or covered glass vessels (cups, vases, aquariums, etc.).
If you have invested in a grow tent or greenhouse cabinet, these can be a great way to increase the humidity for your plants.
Alternatively, you may also use a humidifier to increase the ambient humidity for your home. For convenience, we connect our humidifiers to smart plugs so that we are able to schedule the hours we want them to run and only need to remember to refill the reservoir.
