Hi,

One of my plants was growing much slower than the other, so I adjusted the height of my LED light to be closer to the seedling. Now the cotyledons are yellow and a bit shriveled. I raised the light back up, but is the damage permanent? Have I killed my seedling?

Photos? Cotyledons will naturally fade and shrivel over time. How many sets of leaves?

No true leaves have sprouted yet. I'll grab a photo and be back.

This is the other one. There is some damage due to a botched transplant.

This is like really lame telemedicine. Where you better hurry before the remote expert wanders off from the wait.

Doesn't look good, IMHO. This is deathwatch material if ya ask me.

The second sample looks ok.

Does the stem produce any photosynthetic activity? I'm thinking of removing some soil around the stem.

Yellow cotyledons are a bad start if primary leaves haven't emerged. It usually doesn't go well if this goes badly. There is something not happy, usually a root or fungus issue.

It was looking good until I brought the COB LED like 6 to 8 inches from the seedling. I keep killing life due to my impatience. Growing is so hard.

Nice try, says the reaper.

I'd say no. not gonna help much. Steep sides, this cup has. Close to not being anymore, I'd say.

So. You probably should be sprouting on a window sill or something (depending on where you are). Getting a seedling environment right can be hard. This takes more skill indoors than most people realize at first. It becomes important to learn from mistakes, move on and try again.

Is direct sunlight too strong? I'll try to cut the sides of the cup and place it outside.

Maybe I'll just leave it be and see if she can heal on her own.

If you only have a indoor light to use you can pop a white polystyrene coffee cup with a few small holes in the base , drop you bean in the seed raising mix and turn cup upside down over the seed this creates a gentle warm white translucent light seeds really do not need direct light to germinate .

Thanks for the tip. I'll try it out. I could probably just dim the light though.

You can also get the plant up off the tent floor creat a good air gap under them . If you are going to use drip trays use pot risers in trays keep plant roots dryer warmer aids in good drainage keeping the plant healthy .

Do I need to buy pot risers or can I prop it up on something? I have some bricks.

I bought some from our super huge hardware store Bunnings , I’m guessing your in the States you could tr6 a garden nursery, I think bricks will just be as cold in my opinion, I made my racks from my wife’s cake racks I sprayed white and use small square pots to sit them on and blocks polystyrene about 10 cm thick the cake trays work well there square and fit the tents great .
