I noticed the cotyledon on Light Saber has been curling, which shouldn’t be happening at this stage. The color looks fine and the new leaves are slowly but surely coming in. Still though, the curling got me worried when I compared it to the flatter and bigger cotyledon on my other seedling (Mango Sherbet – different journal).
After some research, I’m pretty sure the issue is plain old overwatering – something I’m probably doing with my other seedling too.
I realized my mistake was in straight up watering them instead of listening to the thousands of growers on the internet telling people to spray them down instead lol.

I’ve been overwatering the plants consistently, and it’s starting to show through on Light Saber through increased stem growth (stress indicator when secondary leaves are not growing as quickly to match), and through the curling of cotyledon despite their color remaining within normal range.
Been leaving it to dry out for the last day or so, only giving it a misting last night and this morning to keep up humidity and hydration. Seems to be working already, after checking on it this morning the secondary leaves are showing improved growth and the cotyledon seemed to have decurled a bit.
I had the seed on a 24 hour light cycle the last few days to help provide the extra energy needed for leaf growth, but as of today I’m switching to a 20/4 light cycle during veg.
The humidity outside increased quite a bit with incoming rain, so I turned on a small dehumidifier to help keep the humidity levels between 65% and 70%. It’s an ideal range to keep the three plants I’m housing together in different growth stages comfortable for now, though I may work on decreasing it to a solid 60% as the seedlings grow a bit.

I’ve been out of town for several days, and using an outlet timer left I Light Saber on a 20 hours of light/ 4 hours of darkness cycle, with misting twice a day from my house-sitter using plain filtered water I’d PH balanced.
I have two small fans running (though one was plugged in to the timer as well, and was off when the lights went dark); one pointed above the plants and one pointed below for good circulation.
Light saber also gets rotated in half turns 2-3 times a day to get a nice, even coverage of light all around.
I left the dehumidifier on the entire time, which was definitely a good thing with how humid and rainy my city got during this past week. Even left on, the humidity level in the room stayed at about 66%-67% - which is about right where I want it right now, so it works out for now.
Misting the sprout instead of watering made a huge difference, and the growth came through pretty strongly after only two and a half days of just misting. The cotyledons never de-curled, but they did get larger to compensate for the lack of light contact so I wasn’t too worried.
Overall super pleased. Light Saber is growing up beautifully; the stem length isn’t too long or turning red so at least for now it isn’t stressed for light or temperature, the leaves are growing in big and well defined without odd coloring or texture, and in extremely exciting news the next set of leaves are already starting to grow out.
Final note for this week before posting – finally got my grow tent (5ft tall, 2ft deep, and 4ft wide) this morning. Setting it up today, so week 3 posting will occur after a full seven day run with the tent. My other plant has been a bit slow to grow due to some mistakes on my part, but after seeing the kind of growth week 2 brought Light Saber without a tent, I’m insanely curious to see what kind of difference having one will make this next week.
