    Default seedling heat mats

    hi everyone...

    i need to rehabilitate a psychopsis. ive tried the old sphag and bag, and got a couple of roots, but it then seemed to stall.

    ive read on the gw forum that heat mat + sphag-and-bag = good stuff, so im going to try it.

    any thoughts on using a cheaper people heat pad with adjustable heat vs an official seedling heat mat? ive got one of those plastic storage drawers that im planning on lining with damp sphag. i plan on opening and drawer a little to allow in fresh air. the top is translucent to let in some sun. will the person heat pad be too hot, even on the lowest setting? the heat pad would be placed underneath the entire drawer (so heat source not touching plants).

    have any of you tried adding heat to the sphag and bag routine? to what success?

    thanks in advance!

    Only tried the spag,n,bag once & that is to try to get some Onc backbulbs to grow.May be i,m to impatient but after 3 months a no sign of growth i decided to try it with some additional heat.

    I have redone the spag,n,bag process & placed the bag on top of my ADSL router.It has only been a week so to early to say if it is successful or not but the bag is full of condensation all the time.
    You could fold a towel or something similar & place this on top of the heater pad to reduce the amount of heat getting to the "patient" .

    I recently domed a seedling that had stalled - covered plant, pot and all, over a humidity tray - and in a short time it has begun to grow out another pbulb. just misting somewhat heavily and keeping it covered, all else is the same. it's doing great.

    My worry about the personal heat pad is the temp. The mats made for seedlings produce very little heat compared to the ones made for people. Plus the heat pads made for personal use are not recommended to be left on for extended time (fire hazard).

    If you do try this method, I would keep a close eye on the temp.

    Sorry, other than that I do not have any recommendations beyond the spag+bag routine.

    Cheers!

    did your seedling prefer ventilation? or do you think its more effective to just have the warm, moist air?

    thanks, bru. ill be sure to check the temps. i didnt know that the personal heat pads were fire hazards when left on for a long time...i just thought that the warnings not to leave them on overnight were geared towards older folks who might burn themselves because they dont sense the heat.

    the dome is not completely closed - i didn't tuck the open end of the bag into the gravel of the humidity tray-however airflow is fairly restricted. I believe the consistency of warmth and moist air is helping, a microclimate kind of thing, reducing stress to the plant. i know this doesn't really address your question regarding heat pads - lately I haven't had to think about the heat, weather's been warm enough on it's own - but all else being equal....well, good luck.
