Pruning?
Pruning ideas along the stems? Was thinking that some of the branches at the bottom that may never get over the lid of the pot should be snipped off. Also, good idea to keep blue/red light shining under the canopy?

Light Science
Has anyone watched some Youtube videos by Dr Bruce Bugbee from Apogee Instruments? I find his lectures on lighting to be the most straight forward explanations I have heard yet. I found his vid called "The New 400-750 nm ePAR Range Explained with Dr. Bruce Bugbee" to be eye opening on lighting colours. I have changed my LED's based on a few of his vids. He explains what plants really want and those Burple lights just don't cut it. For those that don't know he is a professor at the University of Utah that legally studies cannabis growth. He takes the science of weed grow to a whole new level.

Lights too close?
While trying to figure out why my plant is so dwarf like I realized it might be the height of my lights. They’ve stayed that position ever since installed them. The problem is they’re basically at the ceiling of my box. Is my set up limiting its growth too?

Hello grow masters! I would like to ask you if mh 250w and hps 250w are good for veg (the fist one) and flower (the second one) in my 80x80x170. I would appreciate some opinions and advices about my 3 ladies too. Remind that this if my first indoor grow so don't be bad with me!

Information on led grow light.
I am growing one plant of OG KUSH AUTO strain from Nirvana with light setup of 200watt of white led flood light and 300watt of led grow light. Is this much light enough for a single plant? I am using soil as grow medium.

Maximum
I have the LM-3100 Light Meter app on my iPhone using a piece of paper to diffuse like it instructs but I am not sure what the optimal Lux/FC should be. Specifically for LED lights, it is confusing. I have a viaspectra P2590z what’s the max/optimal light?

Switching from led to hps for flower?
Howdy, does anyone switch from a blurple led board for veg, to a hps or similar style light for flower? Why, why not? Is it worth the little extra hassle to buy and install? I like my led just fine, but wondering if there’s more to be gained in flavor, quality & yield. Thanks!

Lux Meter Apps on Smartphones
What are your thoughts on Lux meter apps? The app on my Samsung Galaxy S10+ is showing 16,600 Lux at the tops of the seedlings, and converting that to a rough PPFD shows 222.55/umol/s/m². Reading more, 15k-45k Lux and 200-400 PPFD is good for early veg. What are your thoughts?
