I think I nuked my garage plants?
Apologies if this is the wrong place to post. So I randomly started to turn my garage into a (sad?) greenhouse because I live up north and our winter NEVER ENDS. I had a few plants I had been growing by a window, and when I brought those out into the garage under the "old lights," they were thriving. I have my starts on the bottom, and they have their own light source, but they're growing right quick, so I was trying to plan ahead and make space for them and even MORE PLANTS. Well, naturally, Id need another light source.
This is where things went awry. I put up 3 light boards (pictured above, I dont know if it even says how strong they are??) on each shelf. Then, I removed my fresh healthy marigolds from their warm starter home and put them in small pots. I put the marigolds along with some slightly older zinnias and some other random flowers on one shelf, under the lights, bright enough to land an airplane. I went to bed, eager to see how happy and healthy my plant army had become overnight.
Well. Imagine my surprise when I go out to the gardage only to find some very, very unhappy plants. The ones on the bottom, still under the old lights, were fine, living their best life. But the ones under the new lights more or less got nuked.
Now, my very basic googling has led me to believe I may have violated the transplant/root shock provision as well as the light shock provision. I feel like I can figure out the transplant stuff, but the light stuff clearly has me flummoxed.
Is there any hope here? Like, are the lights wrong, is the setup wrong, is being in a grungy garage wrong? Am I wrong?
Anyway, any insight from people who know what theyre doing is extremely appreciated. Please advise.
