Hi guys,

Desperately need some advice with a recent planting. I planted 1500 seeds into a hot box and placed them under my light. Unfortunately I was in a hurry on Friday and I either didn't sterilize the soil properly or I didn't allow for the soil to drain. By Sunday I had patches of mold appearing on the soil. I took the lid off today and placed them in the sun to try to kill the mold and allow a bit of moisture out.

Will that work and if not what could I do to kill of the mold without effecting the seeds?

What are they? My only experience is with Hylocereus so if they are a desert species then my input might not be very useful.
I don't know much but a good fungicide might work. I like sulfur but something water soluble might be better in this instant. If you have mold then another serious danger is attack by insects, so if you cannot get rid of the mold then make sure to keep it sealed when you're not looking.

3 options;

1. Mix up some fungicide in a spray bottle spray them and then let them dry out completely in the open air, avoid the sun. Once the soil is completely dry you can apply 'some' water and start the germination process again.

2. Take the top layer off, making sure you collect all the seeds. Wash the seeds and soil in a diluted mix of white spirits (metho) for about 5min. Dry seeds and soil and start again.

3. Keep in open air and allow to dry completely, water and start again (probably won't work).

Personally I would do option 2

Thanks for the info guys. They are a mix of loph and mams so collecting the seed is almost impossible. I sprayed them very lightly with a weak mix of copper yesterday and there seems to be no more mold at this point. I'm a bit reluctant to allow them to dry out because some have germinated already but if worst comes to worst I can always remove those ones and let the soil dry out properly.

Yeah If some have germinated that makes it more difficult, seedlings will survive if you replant them early just keep the roots moist.

Some moulds are not a problem for seedlings others are fatal. I often see furry mould on seedling pots and sometimes smell mildew but I don't treat them unless the seedlings are turning to mush, often they grow healthy even with the mould.

I find the fury stuff stops the seeds from germinating. Greenish coloured mould seems to not cause too many problems.

Yeh now I think about it your right Hn. The seeds won't germinate as good when that mould is present, I had always just assumed it was the seed had gone off and the unviable ones were the source of the mould.

The green may simply be algae.  White/furry mould on the seed may be the seed rotting within the casing as a result of being too wet/humid for too long.  Similarly if the seed is too old.

I wouldn't panic and sadly I think by putting them in the sun to "dry out" your probably killed anything that was trying to come up. The fine roots the seedlings have initially won't take any dry heat. Would be handy to see what the mould was if you can get a pic? As Crypto said, sometimes it can be pretty benign and the germinating seed will easily outpace the mould's formation...
