Barrie Posted November 30, 2007 Report Share Posted November 30, 2007 Could some one please tell me what is the lowest temp that Java Fern will live at? I have some killis that I want to put outside and was thinking of floating some on top of the tanks These Killis can live (and prefer) lower temps so they should be fine over summer Quote Link to comment Share on other sites More sharing options...
Caryl Posted December 1, 2007 Report Share Posted December 1, 2007 If the killies can cope then the Java will as well Quote Link to comment Share on other sites More sharing options...
michael.qian Posted December 1, 2007 Report Share Posted December 1, 2007 I read somewhere Java will grow better at lower temperatures, but they are very hardy and can tolerate just about any conditions. Quote Link to comment Share on other sites More sharing options...
Barrie Posted December 1, 2007 Author Report Share Posted December 1, 2007 thanks Dont forget that a couple of types here will breed at under 10degs Quote Link to comment Share on other sites More sharing options...
Foxglove Posted December 1, 2007 Report Share Posted December 1, 2007 I just left some java fern on a log outside in a bucket for a week. We had a couple of near frosts and some very hot days... - result was a lower water level, and the leaves out of the water died ( no surprise!) and the ones just below it went a silvery bronze colour, I guess they got burnt, either by frost or sun.

wilson Posted December 1, 2007 Report Share Posted December 1, 2007 i had some in an ice creal container here over winter some days the water turned to ice the java fern died off bu is now re growing :lol: should be fine Quote Link to comment Share on other sites More sharing options...
jim r Posted December 1, 2007 Report Share Posted December 1, 2007 I left java fern out in winter behind a garage with no sunlight and it survived (did not thrive for obvious reasons) Quote Link to comment Share on other sites More sharing options...
Barrie Posted December 1, 2007 Author Report Share Posted December 1, 2007 thanks I will make a lid out of laminated glass to try to avoid the UV burning and see what happens Laminated glass will cut out 99% of UVa light although not too much of UVb. It will be an interesting to see what happens Quote Link to comment Share on other sites More sharing options...
Warren Posted December 1, 2007 Report Share Posted December 1, 2007 I have mine growing like crazy directly under a 250W metal halide (only 250mm away). It's fine either in or out of the water. The emergent tips of the plant do not die. It is much lighter green in colour than normal however. The tank temperature ranges from 26-30 winter to summer. Java fern is pretty tough and adaptable. As Caryl said, it will cope with anything the Killi's can. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted December 1, 2007 Report Share Posted December 1, 2007 As stated, if the killies survive so will the java fern. There are a number of Java fern types and I am not sure about each one but would suspect they will be similar. It should grow well with sunlight from above but if it "dies" I would leave it as this is often where plantlettes develop. Please report back.

Caryl Posted December 1, 2007 Report Share Posted December 1, 2007 I think I might put some out in my pond at the edge and see how it goes. Quote Link to comment Share on other sites More sharing options...
