4. Planning on lowering temp in the tent, since now there are two led lights running and generating good amount of heat up to 82.
No need to lower your temps in tent (82).I switched to led 18 months ago and discovered in my research that led lights run more efficiently in the low 80s,so i keep my temps between 80-85 if possible.
The higher temps have no detremental effects on the plants at all.
Your plants are looking great mate.
