San Pedro Seedlings turning brown!! (Pictures)

[ebraze]

I germinated about 40 San Pedro seed a couple of months ago and they looked great until I saw them recently. They're in a plastic wrap covered pot, getting misted once a day. They're on top of a heating mat and about 4 feet and to the side of a 1000 watt hps light. Any ideas on what could be going wrong???

the photo above shows their condition this morning. The picture below shows them about a week or two ago.

The light may be a bit strong for them. Hard to judge the color under that light, how do they look under natural light? They don't look bad afaict.

That's a pretty heavy duty lamp for young seedlings, even if they're a few feet away. Probably light stress.

Why would you keep Echinopsis pachanoi in humid conditions? In the first photo they look very etiolated.

Why wouldn't you? Cactus seedlings grow quickly and are easy to care for if kept in enclosed sterile conditions at high humidity. I don't think they look etiolated. I don't even think they're in any trouble. If anything, the light may be a fraction too bright, but the colour doesn't look dangerous. Of course they may all be rotting from the tip down, but that wouldn't be my first guess

At what age do you take them out of humid conditions. I normally take mine out after 2 month. If they are turning brownish red that sounds like too much light to me

Let them grow a bit more maybe double/triple the size.
