totally agree with you! Sometimes general growing advice doesn’t always work in specific conditions, especially when growing indoors by the window. What other interesting lessons have you learned in your first year? And how are the results with your cookie killer auto so far?

I have tortured, maimed, and killed many a plant in the name of science. My oldest son, the city horticulturist, has stood in the grow rooms and asked me too many times if I enjoyed working in the Nazi concentration camps in my previous life. You never really know the limits until you try for yourself.
Light is always directly proportional to yield assuming all of the other factors are not impeding photosynthesis. My estimation on minimum light may be off on second thought. This is an auto flower. I never experiment with autos because you can not have a genetic clones for repeatability and controls. Autos are all ruderalis hybrid. Ruderalis in nature grow in a slightly lower DLI. So the minimum light for flower could be a touch lower. I found a DLI of 11 was the fall off point that separated fluffy pistol clusters from a small but smokable bud. That translates to roughly 12 hours of 12wats LED/ square foot for scale.

That's a good question. I would love to share what I learned my first year, and I will when I'm not exhausted from still processing my first outdoor fall harvest. Lol I had no idea what was going to be required to do this.
I will provide an answer to this when it is a better time.
Otherwise, you can see first hand how my results are with the Cookie Killer in the living room window in the link in my signature. So far it couldn't be any better for an indoor plant.

PS For what it's worth, I don't see how you could get an indoor auto to look any better at 3 weeks old.

I totally get it, the fall harvest is always a lot of work! When you have the time and energy, I'd love to hear about what you learned in your first year. Good luck wrapping up the harvest!

I'm starting some plants from seed in front of a southern facing window. I'm in southern NY state and I'm figuring there is nowhere near enough light because two of the plants have already started to show budding after only a few weeks. I've got to rig up some artificial light soon so I can get them back to the vegetative phase b4 its too late.

Autos stretch out getting spindly photo just jump into flower. Neither will have enough sun light alone for a decent harvest. Incandescent is the only type of light that wont effect reveg or flower. The sooner you can get anything on it, the better. Good luck.
How so?

Incandescent don't have enough of the spectrum or photons that plants use. I am referring to standard tungsten light bulbs. The old screw in 60 or 100wat type. HP lights are technically incandescent but not what I was referring to.

FWIW, here's my 5 week old auto today. This has been nothing but fun so far.
