That cacti rocks. I have some little dumpy yellow, blue and red balls I got the other day which I haven't had the chance to identify. The fell of root stock at a local nursery, so they just gave them to me. I'm going to let them recover for a little while and then graft them on to some Hylocereus which seems to be growing like a weed lately. It's a shame the stuff never bloody fruits, not that it tastes very good, anyway. But, it still looks cool.
I write too much. I write for Uni, I write for my dissertation, I write for freelance jobs and I write for the fun of it. I've written a fair few short stories, a couple of which are in circulation and a novel which will hopefully by published later this year. I know what you mean about forgetting things. If I wake up after a dream and it was good, I'll write it down, but other than that, I don't bother. Yeah, I've got one of 'those' kind of memories. It gives a lot of people the *****. However, I can't draw, nor could I, even if my life depended on it. It's a shame really, but I guess you can't have everything, right? Can I ask, what do you do in terms of occupation?
I'm of the same mind as you when it comes to HL neps. I use the net baskets too. The only two low-landers I have are inside in a terrarium. My problem is the temperatures here (here, being Western Australia). Summer day time temps get over 100 and seldom drop below 50 - 60 at night. Winter on the other hand hovers around 50 in the day, sometimes lower, and will often drop to 0 in the night. I think hybrids might be my best choice, though as luck would have it, I seem to be having some manner of good will with this latest N. venti... it hasn't formed any new pitchers, but it is growing like a weed. I was thinking maybe I should attempt to feed it.
You mentioned fungus. Have you ever had this grow in a terrarium before (hundreds of little white heads forming on the spag moss)? If so, how did you treat it, or what do you think would be good to treat it?
