Thanks for having a look everybody, some of the stuff doesn't look as good as it does in the photographs right now. Recently I had a small disaster. It's so easy to make a mistake and then everything has got algae growing inside because the water that I used wasn't clean. I think I'm going to have to take a lot of stuff out and plant it up. To be precise, 50 Indicas and 50 psstacinas. The rest of them look like they are okay for now but time will tell. PPM is in my regular recipe. It's wonderful for fungus and mold but, it doesn't stop the algar. It is a systemic things so after a while you can get away with not using PPM in second and third generations although if you want to be prudent you can still leave it in.
I have found that growing tissue culture can be like growing cephalotus at times. You can spend a whole bunch of effort and love to grow it carefully and all you need is one mistake on one fine day and the whole thing ruins. Granted, tissue culture grows much faster, but, cephalotus is a lot more forgiving when you make a mistake, at least you can salvage it. With tissue culture is something crashes, you just have to throw the whole thing away. I've tried salvaging things, sending them through a second round of bleach, it just doesn't work out that way. Sad but that's the truth.
