Any yard and garden store has anti-fungal powder (For plants! Not the stuff for feet! lol) and/or spray for plants. Mold is common in those little greenhouses and can kill all your plants if not treated soon. It used to happen to me, but I started treating the entire container before I put the dirt or seeds in. sprinkle a fine layer in the bottom of the pots and then a layer on top of the dirt AFTER planting and watering Just follow the directions on the container or ask the yard and garden person)
Reply:it sounds like powdery mildew... when you water your plants you want to avoid spraying the leaves. water at the base of the plant. also the humidity in your green house may be to high. you should allow a little More air circulation...



control: spray a mix of baking soda and horticultural oil on to the leaves...let them air dry...prune out affected areas and dispose of plant litter...



powdery mildew can and will spread to other plants... you should be able to find the oil at Lowe's...



good luck and happy gardening
Reply:it could be a fungi, but i would put it down to be being wool aphid, put some oliv oil on a cotton bud and coner each spot with it.

pity no one can post pics on here as it would be a great help.
Reply:take some to a garden center, and they can tell you what it is
Reply:Sounds like a fungus. Try spraying the plants with a baking soda solution and increase your air circulation.

Solution: 2 tablespoons baking soda mixed in a gallon of water.
Reply:Chances are good that the white spots are fungus resulting from the high humidity and lack of ventilation in your mini-greenhouse. All greenhouses small and large need adequate ventilation to discourage fungal problems, therefore leaving the top of your greenhouse open for 1-2 hours every day should eliviate this condition.
