Does anyone have this plant in a low/moderate light, soil based tank? Is it really "compact" (one seller says it is a 6" bush) or is it another plant that takes off and turns into a monster?

I've grown it successfully in a "desert mix" under gravel with bright ambient light, we have a lot of that here.;) I have found it to be relatively fast growing.

PlantGeek.net - Hygrophila corymbosa 'compact'


It can be a monster, while the height has stayed under six inches, it has spread out, big time. I noticed in looking about some say it will grow to ten inches tall and to 60 or more inches wide.

One source, Hygrophila corymbosa Kompakt , suggests planting it in a pot. I think I will do that in the future.

I'm growing it in a tank that has low - medium light (approx 40 uMol/m2/sec at the substrate) for 8 hr per day. Substrate is Eco Complete. The tank has EI dosing and CO2 injection. Water is approx 3-4 KH, 9-10 GH, temp is 82F.

So far, it is doing very nicely - after shedding a lot of leaves for the first month or so, it has settled in well and looks happy with very bright, fresh green leaves (no red tint like in the picture on the web site Biollante links to, though). It has grown to about 4-5" height so far.

It is not spreading aggressively, but the relatively modest light in my tank keeps everything at a manageable growth rate. Your experience may differ if you have lots of light.

Cheers,

Sounds like the tank and plant are doing well!

It is a nice plant, I would just say it can be a bit messy and has a definite desire to spread. My mistake was not aggressivly trimming it back. or dividing the plant. I tend to be a bit lax managing my plants.

My experience with this species is that they would definitely try to grow out the 6" mark. I have seen them growing in a ADA Amazoina II substrate to a height more than 10-12 ". That was in a friend's tank and he is bit lazy. My personal opinion is that they are fantastic to look at and regular pruning can keep them in a bushy shape. Low light intensity also can trigger them to start growing tall

I have been thinking about how plants grow in my tank. I keep a low intensity near the substrate, around 40-50 micromols PAR. I get nice slow growth on plants, get content with that, but as the plants grow taller, they reach the much higher light intensity higher in the tank, and grow faster. Then as they get higher still, they take off like they are in a high light tank. This has to be common, since you can't have a low light intensity all the way from substrate to water level, unless your light is several feet above the tank.

This H.c.Kompakt may be a plant that if kept pruned down below the high light height in the tank, may remain as a slow growing, low plant. If I ever try it, and I almost certainly will, I think I will try that. This may also be why "carpet" plants can suddenly fill the whole bottom half of the tank. Light is so tricky at times.
