Water Lettuce in the aquarium

7 Mar

Water Lettuce is a plant normally grown in outdoor ponds. I brought some indoors 2 years ago. At first the plants exploded in growth, multiplying like a weed.  But, over time, these plants got smaller and their reproduction slowed.

Eventually I was left with thumbnail-size Water Lettuce plants. Outdoors they can be 4 or 5 inches across.

A few months ago I moved some of these weakling plants into a half-filled 55 gallon tank. I keep this tank half-filled because I don’t totally trust the stand that the tank is on.

At first there were about 20 little plants.

In a few weeks I had 40 plants.

A few weeks later I had 80 plants. I gave my brother 20 of them. Now there are way over 100 plants, probably close to 150.

I have a 48″ fluorescent light fixture over this tank with 2 forty watt bulbs. These bulbs are new and bright but are just cheap bulbs like you would have in a basement or garage.

I have read that Water lettuce does not like too much humidity but this tank is sealed tight and it is very humid above the water line. Below the water line it is even more humid.

Spring is coming and I have a head start on my pond plants. I’ll be able to put 100 of these outdoors as soon as it is warm enough.
