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

LED light recommendation
I am going to need a new LED light to hang from the ceiling. I am looking for a light that has the red/blue spectrum. A dimmer switch would be awesome- the ones I read about that include-seedling, veg and flowering settings sound amazing. Any recommendations out there? Thanks in

Light distance and power with a 205W Sanlight LED
Sanlight told me I should use it dimmed at 80% and 45cm when in flowering. I was aiming to reach lower buds so I put it at 100% and 50cm from the upper buds. The tips of the leaves are slightly burned but no bud bleaching yet like my last run (at 100% 45cm). What's best ? Thx !

Growing autoflowers, if you gave them 2 hours less than the recommended light; would it just take a bit longer for them to fully mature or seriously affect the yield ?

Veg or Bloom mode for Autoflower?
Hiya Folks 😊 As I'm growing an autoflower should I be using the bloom setting on my LED light instead of veg setting? It's only a 200w system and I'm growing in a 3'x3'x6' tent. My plant has just done 28 days from seed!! Cheers 😉

Reverse flowering time
could I reverse the time when putting into bloom and switching from a 12/12 program? I could turn on at 00:00 and turn off the light at 12:00, because honestly I keep them on during the night and I turn them off at noon and I would like to do the opposite, can I?

Lamp to plant distance: is 40cm enough during flowering phase?
Started with 70cm (afraid to "burn" the leaves), but moved it down to 40cm after checking other grow diaries for auto seeds. Should we keep the lamp ~25-40cm away from the plant from now on? *Lamp is a 300W LED panel (full spectrum)
