What can I say, OG Fun is a lot of fun to grow! And what a sun / grow light-loving beast!
Lighting Update:
I noticed the intense 12:00p sunlight (peak intensity) pouring through the window onto her while the LED grow light was running–probably too much light for a seedling, although she was fully upright and the leaves were green and tilting toward the sun.
I knew from my Bannizzle experiments (my past grow) that higher light intensity during vegetation and flowering produced bigger yields. And that notion was reinforced by this study (for flowering): https://pmc.ncbi.nlm.nih.gov/articles/PMC8144505/
But I hadn’t checked to see what light intensity is best at each stage.
I downloaded the Photone app (a well-reviewed grow light meter app) to measure light intensity (in Photosynthetic Photon Flux Density, or PPFD, which is how many photons of light the plant can actually use every second). Then I made a homemade diffuser out of printer paper (per the instructions inside the app) and found that my light intensity (1,000 PPFD with the grow light and sun combined and 765 PPFD with the sun alone) was well above their recommendations for a seedling (100-300 PPFD) as outlined in one of Photone’s well-written article:

I decided to schedule my grow light to turn off from 10:30a - 12:45p while she receives direct sunlight (on cloudy days I override the WIFI socket and run the light during this time). I also decided to change my WIFI socket to shut off the grow light at 9:59p (it turns on at 5:59a) so that total light hours are kept to 16. I think this combination will make for the easiest transition for her to move outdoors. I do recognize that the total DLI from the sun added to the total DLI of the grow light for the remaining hours is a bit higher than recommended, but the plant seems healthy and I don't want to make too many adjustments at once.
I also became curious how much DLI she would receive growing outdoors (so I can prepare her for similar DLI before I put her outside). This is a cool tool for that: https://dli.suntrackertech.com/
Finally, I implemented a container rotation schedule (with the Fruity Freak plants I am growing) and now move the plants one position counterclockwise every day. After four days I will turn all containers ninety degrees. This should promote more even plant growth.
Water
I am watering her once a week (my native soil is dense and retains water) using about two tablespoons worth. She only gets melted snow warmed to room temperature or captured rainwater to keep soil pH and conditions consistent with the outdoors.
Airflow
The clamshell is now removed. I am running my ceiling fan during daylight hours. I am also using an oscillating fan while she receives direct sunlight (I am using a WIFI socket to turn it on and off automatically for me) to help cool her and begin strengthening the stem before the transition outdoors. Two interesting articles on the subject:

Thanks for reading! As I am a newer grower, I am always open to suggestions and ideas–so don't hesitate to reach out!
