Nice and sticky so the blocks would hold together but
I'm thinking I need much less compost in a plug mix--more like half peat and
half vermiculite or something? and no compost?
We use a commercial media, but I'd think the basics are the
same. It needs to drain VERY well - especially in late winter/early
spring, or you will have a lot of damping off and/or fungus gnat
problems.
I think one of the mistakes we made last year was filling the plug flats
with moist potting mix. Again, this may sound basic--but with soil blocks
of course you start with the mix nice and wet. The mix wouldn't get to the
bottom of the plugs. So...if I fill the plug trays with dry potting mix,
what's the next step? Do you irrigate first or seed first? If you
seed, andif you're putting on enough water to soak the peat, doesn't the
irrigation water dislodge many of the seeds? Or do you bottom water?
Bottom watering seems like a good plan, but with more logistical fuss...
do you keep bottom watering or then move to overhead sprinkling? Do
you seed first or bottom water first?
We fill with dry mix,
then water the flats, then seed, then cover if necessary and water again.
The only time we do bottom watering is with seeds that need light to germinate
and may get covered with overhead.
However, if the mix gets too dry - say in an open bag - it can take a while
to get it really wet. Make sure the flats feel
heavy.
As far as fertilizer, are people able to put enough granular fertilizer in
the plug mix to support a transplant for 4 weeks, or is foliar feeding always
necessary? (We're talking about organic production here.)
We use a heat-treated,
granular chicken manure , 3-4-3 analysis
I think. It will hold at least 4 weeks, sometimes 6 before the
transplants " run out", but we are not
certified organic and can't speak to whether it would be appropriate for
organic transplant production. It does grow gorgeous transplants! (And
field crops as well)
Finally, if you don't mind, these are the size plugs I'm using for various
plants. Does this all look right to you
72s--lettuce, brassicas, greens, etc, (or are people generlaly having
success with 128s--they're so small!)
50s--cucurbits
24s--tomatoes (or 3.5" pots), eggplants, peppers
128s--for starting tomatoes before potting up(--or is this weird?)
We
use 96s for lettuce and greens, 48s for brassicas, 36 deeps for
cucurbits, 36 deeps for tomatoes for High Tunnel spring. For our tomato
transplants that we sell as transplants, we start in 96s or even 200s and
pot up to 1801s. For spring field tomatoes, we use 36s, for summer, which
will be in the flats a shorter time, we use 48s.
I see the advantages of plugs as being: less time and labor compared
with making blocks, less space used on the greenhouse bench, possibly easier
transplanting (we've played with the hatfield from Johnny's). But there's
no advantage to them if I can't figure out how to grow a high quality
transplant!
You
can! Sometimes it just takes fine-tuning the system. Everything goes
on a germination mat this time of year. Right now we have 8 - enough for
54 1020 flats - and it is BARELY enough for our 2 acre operation (plus
transplants we sell at farmers market).

Are there resources or books people can point me to so I can get my
remedial education on this?
Thanks,
