Terrarium Cooling for Ultra-Highland Nepenthes and Pygmy Sundew Care Check

A grower asks about cooling ultra-highland N. hamata terrarium and confirms pygmy sundew/D. capensis water levels.

Cooling Solution

• Ultrasonic fogger (frog tank type) — cools via evaporation
• Pet stores carry these

Water Level Correction

• 1/3 pot height = starting point
• Let plants USE water before refilling
• Wet but not waterlogged = oxygenated roots
• Same for D. capensis (½ pot max)

Nepenthes Water Trays

• Trays catch excess only — never sit in water long-term
• Windowsill Nepenthes: same principle
• Good windowsill candidates: N. sanguinea, truncata, alata hybrids, maxima hybrids
• Avoid ultra-highland/lowland for windowsills
