@DickJones, looks like it worked well for you!! I’ll give it a go and see if I can lower it. Id be happy at 60% to be honest but lower would be better

Just going to throw this out there but for humidity control take a peek at week 17 of my Durban Poison diary. Basically feeding the tent the dry air from the dehumidifier. It works very well. My only problem is the exhaust fan cannot move as much air as the dehumidifier does being only a 4" fan so the tent does balloon a bit.

@DickJones, thank you, but I actually used multiple small lights. One 40w led with grow spectrum and two LEDs with bloom spec (20 and 7 watts). Yield to watt ratio is not as good, but I think the limiting factors were mostly the short veg time and small space.
