The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

Seeds in 12/12

How to keep room dark during flower?
How important is it to keep the plants in COMPLETE darkness during lights off during flowering? Thinking of running some ducting with cut-to-size furnace filter out the vent hole on the side of the tent which supplies air right now. Will that be enough?

Should I dim my TS1000? Ts1000
When using two lights in a small space should I be worried about to much light? The plant is mature and is about to transition to flower, I’m just curious what is too much if any. The TS 1000 is dimmable the sf1000d is not. Lights are 18” at the moment
