Grow area reorganization

Update on what's been going on with my little grow area. The air conditioner definitely did it's job this past week during the heatwave as temperatures soared over 100F for almost a week, so the phals were safe. Kept the room around 85F in the day and between 50% to 70% RH. Nothing has changed yet for the seedlings in terms of vegetative development. This growing area is by the South facing windows and I've noticed that the roofing is keeping all direct light away from this area this time of the year so I wonder if my light levels are adequate sometimes.

The tiered rack with the smaller plants are on now has a layer of LECA underneath that's kept wet, as you can see here. I keep these phals (and one paph) under a half-cracked dome at night to keep the heat/humidity in.

As for the larger more established plants, they are kept together in a wooden basket by the humidifier that you can see peeking out on the right.

They all get a nice misting in the morning and evening with the fan on. When the air conditioner gets turned on at night, the RH drops dramatically and the humidifier definitely gets a workout when this happens. I'm this close to getting a humidistat to automate this..
