Diferencia en el color verde de las hojasEstas plantas automáticas están recibiendo la misma alimentación, agua, etc y están en el mismo tipo de sustrato. Pero unas (las más oscuras) reciben luz artificial adicional (Neón CFL) para llegar a tener 17h de luz al día. ¿Es normal la diferencia? ¿Cuál se ve mejor?

Electrical power calculationActual power consumption of lights is lower than led manufactorer says.
25 leds of 3W each = 75W plus an internal fan plus some other circuits,Total power should be more than 75W and i calculated 58.3W overall.
Vac=220 , I=0.265A
Any ideas?Setup. Lighting

UV LED slowing down growth? Sorry previous question without the question!The plant has a rectangular area in the middle where it is not growing as quickly. The difference is almost 10cm. I suspect the lamp. Could it be that the centrally installed UV LEDs are causing this? They should grow more inside because of more light.

18/6 leads to high temps in small tent; change light schedule or stick it out?Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete.
Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6Setup. Lighting

Lights too close?While trying to figure out why my plant is so dwarf like I realized it might be the height of my lights. They’ve stayed that position ever since installed them. The problem is they’re basically at the ceiling of my box. Is my set up limiting its growth too?
