Orange seedlings

[maurozzz]

Good day!
I have a question. I’m currently growing Parodia Erubescense from seed. Using a custom substrate and a heat pad in a greenhouse. I got these seedlings in about a week and a half. This is my first time sowing seeds. Just have a question. Why are some orange? Is this normal?


Thank you!!

bit too much light probably. move a bit further away or reduce time light is on.

A pink or light reddish color is perfectly healthy, I wouldn't change anything. The fact that some are green and other reddened is just genetic variability, if the light was too strong they would all be going red.

Better to have the light a little on the strong side than too weak - seedlings grown in too little light grow weak and stretched out, are more vulnerable to pathogens that can kill them. Too much light turns them dark red to purple or brown and slows their growth, but they can recover from that. If the light is strong enough to burn them, that is immediately fatal - but they don't turn red, they turn white.

Orange and red colours are just reactions to the light. As long as they look plump and you see some green in there you'll be fine. You want them to start tough at that age. If it really bothers you, try placing tissue paper over your propagation dome to act as a shade cloth. Adjust as you see fit.
