Drosera binata Seedlings Browning in Tree Bark Plugs

Mark's D. binata seedlings (1 month old) in a terrarium under T5HO lights show rapid leaf browning and die-off despite new growth. They're in "Rapid Rooter" tree bark/peat plugs with standing distilled water.

Media Mismatch

Bog-dwelling CP's expect acidic, tannin-rich peat/sphagnum. Tree bark plugs lack these conditions. The expert suspects the plugs are the problem—D. binata is slow from seed regardless, but the media exacerbates stress.

Fix: Transfer to Peat-Based Mix

Carefully cut seedlings out of plugs with sharp scissors and plant into peat/perlite or peat/sand. Alternatively, bury the whole plug in a peat-based mix so tannins wick in. Lighting (16 hrs, 6400K T5HO at 2') is excellent. Patience plus proper media will resolve the issue.
