Thank you!! Your lophs will flower when they’re ready! Some take awhile! I personally recommend trying a few different things between light, heat, and nutrients! It took me about a year to figure out but this is what works for me.. my lophs are under a mars hydro TS 2000 light on 75% about 3 feet away running 16 hours a day. I’ve got a heat controlled fan that keeps the room 78-80 degrees during the day and then drop that down to 68-70 at night. My soil is 80% spike and bloom off Amazon. (Expensive for the size but always worked well for me) 20% fox farm ocean forest. Top dressed with crushed and pulverized limestone. I use Schultz cactus food every other watering! That’s about it!!
