Just because a plant is receiving 10,000 or 100,000 or 1,000,000 lumens doesn’t mean a plant can use all of them. The plant can only use what it can absorb and breakdown.
To break down the light the plant needs Co2. The average atmospheric Co2 ppm is in the high 300’s. Wikipedia says the average amount of Co2 globally is 391 ppm by volume. The levels can be even higher (up to 600 ppm) in highly populated and polluted cities. It is also higher in the average household as it’s stuck inside with nowhere to go and people, appliances, and sometimes pets producing more and more of it.
Now the a plant outdoors might be receiving WAY more lumens but it most likely doesn’t get as much Co2 as a plant in a home garden. Especially if the plant is in a more remote location and the home garden is in a city closet. Therefore even if its getting more lumens it doesn’t mean it can break the light down as well or as much as the plant indoor. The indoor lighting might not be as intense but it is for longer periods of time and presumably with more Co2.
I’m not saying more lumens aren’t a good thing. They are. But they need help to break them down and outdoors you can’t just force Co2 to the plant. I’m also not saying growing under lights is more effective. All I’m saying is that indoors you have a much more controlled environment. You can do things to help the plant utilize the light it’s receiving much better. While a closet with a 450 – 500 ppm of Co2 doesn’t get as strong of the light if its getting a longer period and has more ability to break that light down the plant indoors will grow much more quickly.
Outdoors you don’t have as much Co2 or hours of light but the hours you do receive are more intense and full spectrum light. There are pros and cons to both indoor and outdoor.
That being said, I am not a master gardener. I do however do my research. This is a forum for the spreading of knowledge and ideas. To help the new and the old to the art of growing cannabis. To share what we’ve learned, good and bad, for the benefit of other growers and connoisseurs.
If you know so much master gardener Rockstar and want to bash people for speaking their own very valid views of growing then maybe this isn’t the site for you. Go back and tend to your own garden and don’t shove your arrogant and condescending views down our throats. Just my two cents.
Other than that c0rd, I’m with you. Gottapercha things look great. They’re doing fine and I’m sure will make you very happy in the end. Keep up the good work.
