Beginner Growing 5 Phals, 2 Vandas, 2 Catts, 2 Dendrobs, 3 Oncidiums -$35 shop light

[annie.exe]

Hi guys! I'm pretty brand new to orchid growing but am having so much fun.

Currently I've been growing several orchids under a $35 Home Depot shop light. I've gotten a lot of new leaf and root growth on every orchid but still have zero flower spikes.

I haven't been using a timer.. Just have been running the lights for about 12 hours a day.... but that varies. I've accidentally left it off or on here and there.

I've moved my Oncidium orchids off to the side away from the light because I'm afraid it's been burning them.

I've only been watering with water. Most are in Leca or are bare root. 2 Phals are in spagna.

I want to upgrade my setup and keep learning but I don't know where to start. I don't have access to natural sunlight so I need to stick with lights, unfortunately. I do have central air and am located near Minneapolis Minnesota.

Any feedback or direction on how I could improve my setup would be much appreciated. Thank you!
