    Trouble with utricula graminifolia

    I tried DSM to grow a carpet of UG (tissue culture) twice and both times had to flood due to mold problems after only 2 weeks. I tried a range of planting methods, from deep into the substrate to laying the clumps on the substrate. First time around fertilized using nilocg thrive and second time kept it on the nutrient poor side due to reports of nitrates causing melting and the fact that UG grows in nutrient poor marshes. Both times injected CO2. At this point I'm at a loss as to why UG melted within a week of flooding.

    10G
    LED light on for 7 hours
    Canister filter with good flow
    Mr. Aqua base layer topped with tropica fine substrate
    Low KH and pH due to substrate buffering
    Salvinia minima on the surface to avoid any possible nutrient buildup to avoid algae

    Any help appreciated.

    Nice layout. From my experience I let the UG float first to adapt it to immerse State. The tissue culture I got was dying from the bottom so I trimmed off the roots and left whatever trimming was left floating on top. UG can grow runners from the trimmed blades. I was able to salvage maybe 1/8th of what was in the cup from trimmings. Once I see about 2-4 cm of growth from trimmings I would plant it. Took about 2 months to fill half of a 60p tank. If you are on discord chat you can see a pic I recently posted.

    What substrate did u use? Any ferts or CO2? It's a carnivorous plant but there are reports of it thriving with those.

    Ug isnt all to hard to grow if you how to do so, there is so much misinformation and even lack of information about it. It actually doesnt need co2 to grow (however it is beneficial) because its carnivorous. Is also doesn't have roots, and stays in the substrate via runners. If you have any other questions, ask southbayaqua on Instagram, he knows everything about this plant.

    I have failed DSM multiple times and never quite got it right, because I had similar issues you did. This is what I have been told:

    If using ADA aquasoil give the substrate a good rinse before using.

    I had used a reptile fogger to keep it moist because I didn't want to spray everyday and I think this was a mistake. I think my downfall has always been too much moisture, hence the mold. I think for my next hand at DSM I am going to provide a lot more air circulation and keep the top very loosely covered.

    When I saw the mold I flooded the tank and had pressurized CO2 running 24/7 (not on purpose but I was too cheap to get a solenoid back then haha).

    I think the CO2 really helped though, and the UG really took off and I had a pretty impressive carpet. I was using a Compact Fluorescent light with ADA aquasoil and I think I was doing EI dosing at the time, but I don't know how important that was.

    Good luck!
