Algae on Drosera Rotundifolia Seedlings: Fungus Risk and Outdoor Fix

Algae Indicates Fungus-Friendly Conditions

Algae on D. rotundifolia seedlings in 50/50 peat/perlite under 16h fluorescent light suggests poor drainage/aeration, low light, stagnant air, or excess nutrients. Algae itself isn't harmful but signals fungus risk. Spray sulfur fungicide, move pots outdoors to 4+ hours direct sun (acclimate first), let soil surface dry slightly between waterings. Low light indoors perpetuates algae/fungus. Choose plants suited to your shady yard.
