A while back I picked up some C. parva and placed some rhizomes in my 5 gallon during a DSM. All but two rhizomes melted. After I filled it up, I was initially using DIY CO2. The C. parva did fine, producing a new leaf once every 2-3 weeks. I eventually upgraded to paintball CO2 and after a few months of pressurized CO2 and EI dosing, it has turned into slender-leafed plant that is constantly shooting up new leaves and runners every week or so.
The leaf blade is about 6cm and the petiole is 7.5cm. The height of a full grown plant is a little bit more than 15cm.
Here's a pic of the entire tank:
27 watt 6500K CF Desk lamp on a timer for 10 hours, with the bulb three inches above the tank.
Tom's Mini Rapids Canister filter for filtration.
25 watt heater set for 73 degrees F.
Substrate is MGOCPM capped with Seachem Black Sand for a total substrate depth of three inches.
Full EI dosing with a 60-70% water change each Sunday with 1/4 teaspoon of GH booster after each water change.
Paintball CO2 with a drop checker (filled with 4dKH solution) reading lime-green two hours after the CO2 turns on.
Does anyone else have C. parva under medium/high light with pressurized CO2 that grows like this? Or is this another type of crypt? I could try growing it emersed to see if it will flower but that takes too long IMO. Any advice or info would be appreciated.
