Pal. At 450w. You shoulda be running at 25% for the 1st week. You shouldn't have to exceed 50% for your whole veg with such a high powered light. So I'd say she's at a right setting now. No need to use more watts that's not needed. Good luck

Best grow light for a 3.5x3.5?
I'm disappointed with my last yield and belive its cause of the light. Want to invest in a better product. Which one do you think will produce the biggest yield with 4 autos in a 3.5×3.5 feet wide tent? - Lumateck Attis 300W - Mars Hydro TSW 2000 300W

Thoughts, good idea or bad idea?
I got an idea from when I was pruning pecan trees growing up. If I install small LED lights directly inside each "window" or "pocket" will that improve total light and production, or will I just burn the plants?

When turn on the lights?
It's pretty warm here right now already. When is the right moment to turn the light on? It's a dual spectrum 300w CFL under a 470x470 reflector and both seedlings are auto fem. What's the best light schedule? 24/0? 18/6? Thanks

Starter kits!
What can I expect from a 600w starter led, I know they're not meant to be great, but of 2 plants in 1.2 x 1.2 x 2m tent, fan kit, filter, etc. I know it won't great an there loads of other factors but say its a good grow, goes well what can you expect with these of good plant.

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

Just wondering if adding sunlight could improve it or makes no difference?
Do you still need to give plants sunlight if they have a tent fan and ac plus led grow lights? I really need to know if after 53 days of 6hours of sunlight daily the plant might be used to the sunlight , although I know led grow lights are like a mini sun inside tent but still?
