Transitioning Drosera adelae from Terrarium to Open Culture

Terrariums Are Unnecessary for D. adelae

Drosera adelae thrives as an open houseplant. Terrariums cause weak growth, fungal issues, and prevent natural insect capture.

Step-by-Step Acclimation to Open Air

1. Prop terrarium lid open 1 inch. Wait 3 days.
2. Increase gap by 1 inch every 3 days until lid is fully off.
3. Repot into a larger container (they clone aggressively).
4. Place in bright window (south-facing, but shaded from harsh afternoon sun) or under 40W shop lights (12,000+ lumens, 5–8" above).

Benefits of Open Culture

• Stouter leaves, more dew, better color.
• Natural air circulation prevents fungus.
• Catches own prey (fruit flies, gnats, mosquitoes).
• Easier observation and maintenance.

One plant can fill an 18×6×8" planter in a year. No humidity tray needed unless ambient humidity drops below 15%.
