    is the rose spray daconil? cuz i read in another forum that daconil works to stave off damp-off and is safe for the little guys.

    i cant wait until ive got my plants in compots. ill be leaving town tomorrow, and im coming back on wednesday. guess what im going to be doing the first thing i get back!
    Also safe (from what I hear) is hydrogen peroxide straight from the bottle (which would be a 3% solution, I think). I just picked the clearys because I have the WP version, and I generally don't like the oils, emulsifiers and whatever else they put in liquid forms (the rose spray is liquid). If I weren't so lazy, I would actually figure out what's in there, but, well.....

    hi, louis!

    ive deflasked both of my mini flasks, and so far so good (knock wood). i went away for a week or so, and then came back and did the deed. i wound up removing the agar because there was so much of it -- about 2 inches deep. the neofinetias are in 2 separate 2.5 inch pots (3 in each). the psychopses are in 2 4 inch pots, with the smaller protocorm-type ones in one pot and the larger ones with more leaves in another. oh, i scooped some agar to put under the protocorm ones and put some of the medium on top of the agar.

    all four pots are under a humidity dome, with a heat pad underneath. i havent had to re-spray with anything (fungicide, fertilizer, superthrive) because its pretty moist and because theres no fungus to deal with, at least for now.

    do you think that im letting them stay too damp? should i give them more air? i remove the dome everyday for about an hour.

    louis (or anyone), if you can think of anything else that i need to do, youll let me know, right?

    What you've done sounds like a winning plan to me. Now all you have to do is.....


















    wait.....

    Well, not surprisingly I lost many (most?) from the youngest flask. It really was not ready for deflasking (even by the date on the flask) - although in perfect conditions by an experienced deflasker, more may have made it. I think I may have lost only 1 or 2 from the other two flasks combined. I also switched back to Physan. Our humidity plummeted about a week ago - as did our temps - and these seedlings have been exposed to it. All that said, I have new leaves on most of the survivors - the porridge that was just right is doing the best.

    Ki, I think you hit the nail on the head as far as humidity goes. Those tiny ones especially--they really need the humidity kept high and constant. What typically happens if the humidity drops is the plantlets dessicate (it only takes one day's worth of cool, dry air), then, with the next watering or misting, fungus immediately invades and rots the crowns.

    If I can't get the plants shipped in their original replate flasks, unless they're from a grower I know and trust, I won't take them. Too many times I've gotten "flasks" of plants that have been transfered into those plastic hamburger containers where the plants were way too young. If they're in their original glass, at least you can grow them for a while like that and deflask them when they're big enough. The survival rate is a lot higher.

    Anyway, I hope it doesn't keep you from trying again.... Glad the others are doing well.

    Actually, the die off happened earlier while growing conditions were stable. Only the remaining seedlings have been subjected to the changing temps/humidity, because I gauged them to be adjusted enough to their new growing conditions. Also, the contents of the flasks were so messy after the shipping, I dared not leave them that way. Admittedly, I knew I was gambling on the youngest flask when I placed the order.

    Hamburger containers sound awful!

    The containers look exactly like what they used to put big-macs in, only clear plastic. Saves on shipping. They're fine if you know you're getting seedlings that are actually ready, but if you get sent things that are still immature, you don't have much choice but to get them out regardless.

    Weird about the die-off, if the environment change isn't what caused it. I'm stumped--wish I had a reason for you. I've never tried cleary's, only rd-20 or physan, so maybe that had something to do with it? Don't know...

    maybe the die-off was caused by clearys? it is a systemic, isnt it? maybe the chemicals were too much for the little seedlings that were absorbing them?

    just a thought.

    ive sprayed mine with daconil + physan, and so far so good. granted, komi did de-flasked sooner than i did. so maybe (but hopefully not) bad stuff will happen to the babies in a couple of weeks or so. jeez. i didnt realize that i was so pessimistic!
