Added the 400 watt HPS this week. These ladies struggled at first as the new light was causing too many air exchanges and dropped the humidity. They were still growing, but leaves looked like tacos. Increased the temperature to reduce air exchanges. Humidity went up. Happy little plants. On the verge of switch to flowering. Waiting till we're up to 16" before making the switch.
Damn gnats! Good luck bud.
((if need be)) Along with your sticky pads, a light neem oil foliar treatment once a week on just the undersides of the larger-lower fan leaves will nip em' in the butt quick. Spraying the top soil a bit can't hurt either. And yes of course watering less often.
Bob Ross!? Too cool my man. New strain to me... looking forward to seeing some
"Happy Little Trees!"
Keep em' coming and good luck with flowering that gal
@PureMedicin, I have my heater set so the temps don't dip below 20 degrees at night. The soil was gets to cold if it gets colder. The color changed a couple of weeks into flowering. Started with purple leaves and then the flowers drifted into pink.
