I can have them basically touching and there be no heat produced. My only concern is that they’re retail bulbs. Like the bulbs you’d use in a ceiling fan. I’ve noticed other plants I’ve grown/am growing all respond different to th light. But the ganja just remains unaffected either way. I just don’t wanna be giving them too much light. I downloaded a LightMeter on my phone to gauge it. Just don’t trust it that much. But .5” away from the bulb, the phone reads 100K lux.
