    Hello,
    I have tried every method that is recomended to stop algae growth in my seeds pots but none of them worked,
    I use scultz peat moss and well washed lawn sand 1:1
    I put the soil mix in the microwave for about 5-10 minutes,
    I reduced humidity
    and still algae grew before seeds

    Im now trying an experiment to find out if algae growth is slowed if a layer of sand is added on top the soil mix

    Ive read that using some charcoal can slow down algae growth, im thinking of doing an experiment
    anyone tried this before?
    any Charcoal can be used right? The ones for barbecue?
    Do I add a layer of charcoal to the top of the soil mix like i did with the sand or mix it in with the soil mix

    thanks alot, those ALGAE has killed enough seeds already!

    You'll have to hunt for charcoal carefully. Most bagged charcoal for grilling has lighter fluid already added to the briquets. You sure don't want to use that! It will say easy-light or something like that. We never use that stuff even for grilling because it stinks so. We buy ordinary charcoal briquets from Wal*Mart. I just wanted to put in that warning - I don't know if it will help the algae problem for you, though.

    Hi Wezx

    There is HORTICULTURAL charcoal. Most garden centers should sell it. It comes in small bags. I've seen larger chunks and a finer grade.

    Check Lowes, Home Depot or your local greenhouse.

    And I've found algae almost impossible to get rid of no matter what you do. I have it in some pots and but not others.

    I waived the white flag long time ago in this battle. But then again, I've never had so much that they've affected growth or seeds/seedlings. I now just scrape off when it appears.
    DOH!

    DO NOT USE briquettes. Horticultural charcoal is made from carefully charred wood of certain species. I have a recipe somewhere on how to make your own hort charcoal. It's a long process. Besides the briquettes will make your soil or whatever black and yucky.
