I'm not sure where you live. But if your plants are drying out too much, you can just water more.
I don't use overly water retentive media because I live in a place where its extremely hot and humid. I only have a greenhouse to protect my plants in a very very brief winter here. Otherwise, its been characterized as the Ninth Rung of Hell here.
I have to water pretty much daily. The epiphytes need that much water here to combat heat stress. And I have a 36 ft back vent and two 4 ft x 4 ft exhaust fans that run pretty much 24/7 here in late Spring, summer and well into fall. SO the air movement is constant, which also helps things dry.
If you can't water more frequently and feel you need a more water retentive media then add vermiculite.But the aim of most 'chuncky mixes' is to REDUCE water retention and promote drainage, not facilitate it
I use those baskets extensively for epiphytes. They work well. But they do their job...they allow free drainage of water.
These plants below are all in chunky mix in a coir basket
