18/6 then 12/12.......there is no other.
Sometimes if you have a plant with heavy Sativa genetics, you can go to 11/13 to help them finish more decisively and prevent continual re-flowering at the end (last 2-3 weeks).

Once your happy with the plant size in vegetation, you should just flip straight to 12/12. That’s the most common practice for flowering.

Doubling light/adding a panel in flowerAdding a second light panel-- any tips? Will it be too much?
I've been using a viparspectra p1000 in my 2x3ish closet and it's done me well up to this point. Today I've installed a second led panel (not as good as vipar). Wondered if it'll be too much?Setup. Lighting

100W full spectrum enough for 2 plants in a 80x80x160cm tent. Should I get a 300W instead?So, I bought this light, it's a 100W full spectrum grow light. But I think I might've bought it too hastily. I want to ask you guys before I return it though.
Do you think I should get a 300W instead? Planning on growing 2 auto plants ScrOGed.Setup. Lighting

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 😉Week 5

Are these LEDs good?What do you growmies think of these lights? They're LED's, I have 2 of these going and a few other lights. These though, I don't understand much about electrical info. My green seems to like them ok but are they good? I know to the experts out there, this probably seems dumb, butWeek 10
