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

Hps mixed with mars hydro 600 yield?
Hey all! So i been thinking about ways to cut heat of course lol. So I’m thinking about getting a mars hydro 600 and running it with my 400w hps at 250w on the dimmer. Do you guys think I will yield about the same as if I was just running the hps on super lumens?

Upgrade from 300w mars hydro TS to FC/FCE?
Will I get noticeably better quality results like denser heavier buds and more resin if I upgrade my light from mars hydro TS series to a bar light with higher red spectrum?

Slow indoor seedling growth
4 days since sprout, issues with light timer, seedlings ended up getting 48 hrs of light after they sprouted, and this AM I found that the timer did not turn the light back on so it got 11 hours of dark last night instead of 6. Could this be detrimental to seedling?

Changing light cycle on seedlings?
Can I run autoflower seedlings under 24/0 light cycle until they reach mature veg stage, and then move them into an 18/6 light cycle? I’m starting seedlings in a space tote, then transferring to a large tent to mature. Will the light cycle change have negative consequences?
