    Re: Purple mold while germinating?

    Lets ask a few questions: is your water filtered, soft hard? What kind of paper towel? Any type of accelerator? Any odd scents? Where are your seeds from? Some commercial seeds can have coating such as fertilizers. Some kitchen paper products can be made from corn starch or other grain pulps which can mold. (Wet corn starch products in particular can mold in purple). It is possible it is also just a random mold spore or yeast spore from the air. Any food products been prepared near your seeds? Also, the purple off color could be from the seed casing. The brown color might. Just bleed off the color purple.

    Re: Purple mold while germinating?

    I would believe that the seeds had a coating that caused the coloration. It looked more like color run off than mould. As far as the questions to surmise what caused this. The only rebuttal I can give is that there were 4 separate controls; the only difference were the seeds.

    Re: Purple mold while germinating?

    If the mold is only growing around the seeds, there were spores on the seeds before you stored them.

    I'd try germinating on a soil-less mix. The peat moss in the mix has a ph too high to support mold growth. You can also use a super fine dusting of sphagnum moss (old fashioned worm bedding) over the seeds after they germinate.

    What will the mold hurt if he moves the sprouts from the paper towels to the flats?

    I don't know, that's why I was asking you. I seeded direct to soil last year and had what looked like mold form on the surface of the soil, but it never spread to the plants. (it could also have been minerals rising to the top)

    I have had fuzzy mold grow on my dirt also when sprouting seeds. I thought it was normal due to the warmth and high humidity.

    Keep going, you might come up with a mold resistant strain that won't even mold when color curing in rainy weather.

    I had some mold/fuzzy growth in mygermination trays also, but once the plants were divided into cells it never reappeared. No harm, no foul i guess.
