Propogation mats

I can't say with any certainty that propagation mats really make a difference.
i tried a mat last year, my seeds germinated, but like was said before, it's
tough to heat a 4" peat pot.  they also germinated the year before, and i didnt'
use a mat.  i can't see it being a bad thing though if you wanted to try it out.

Subject: propagation mats

I've recieved my yearly supply of garden catalogs lately, and always am
intrigued with the products offered. Many offer propagation mats for seed
germination which I've often thought would be nice to have. Has anyone used
these or have any input whether pro/con on these? Also does anyone recommend
a certain brand. Pumpkinpiper

   I have tried the propagation mats.  They are great for flowers and
vegetables but they do not heat the larger containers like the large peat
pots well enought to help.  I put my pots in the oven with the pilot light on
high and it keeps the seeds @85 to 90 degrees.
   If you use this tenique make sure youtake the control knob off so nobody
preheats the oven without checking to see what is in it.

THis past year some of my pumkis had a black mold inside on the shell.
What was strage was that you could ot even see any kind of bruise/blemis
mark on the outside--only when you carved it open did you see this!  Of
course this caused the same pumpins a much shorter life after they were
carved!!

Anyone know what this black mold/fungis os from and what cause it??  How
does it start from the inside???

Thanks,

Randy

Subject: Determining Heat Cable Needs

I remember a discusion of heating cables a while back.
Here is a short artical that I found on the subject,
that may be of some use.

Determining Heat Cable Needs

                               Larry A. Sagers

Electric heat cables are a convenient and dependable
way to heat hotbeds. Cables
are covered with either lead or plastic to prevent
electrical shorts. Roof heating
cables and heat tapes are not suitable for direct
burial.

Cables vary in length and wattage rating. Some are
rated at 6.7 watts per foot while
others are rated at 3.5 watts per linear foot. Cable
is installed to produce a certain
number of watts per square foot of bed area.  Plan on
allowing 12-15 watts per
square foot.

Lay the cable on loose, level soil or sand. Be careful
not to damage the covering
of the cable. Avoid kinks that could damage or break
the cable, and don't cross
cable over itself. Never cut
the cable to shorten its length.

The spacing between the loops of cable determines the
number of watts supplied
per square foot of bed. Use the following formula to
determine the spacing
between loops:

     Spacing (inches) = (15 x watts per foot of cable)
? wattage required per sq. ft.
of bed

To determine the watts per foot of cable, divide the
total number of watts for the
cable by its length in feet.

Example: Spacing for a 400-watt cable 60 feet long to
produce 15 watts per square
foot of bed area would be:

     Spacing = (15 x [400 ? 60]) ? 10
     spacing = (15 x 6.7) ? 10
     spacing = 10 inches between loops

The factor used here is 15, spacing for 12 watts per
square foot of bed area would be 8 inches between
loops.

If the heating cable is too long, use spacing slightly
closer than calculated, but
always distribute the cable uniformly throughout the
bed. Irregular spacing makes
temperature control difficult. Generally, a 60-foot
cable should heat about 36
square feet of bed area.

After the cable is positioned, cover with sand or fine
soil. Over this, place
half-inch-mesh hardware cloth. The hardware cloth
protects the cable from
damage when soil above it is being worked for
planting. Over this, add the layer
of soil for planting or another layer of sand if all
planting is to be done in beds.

Thermostats.  Use a thermostat to maintain uniform
temperatures. Some cables
have built-in thermostats that keep the soil
temperature close to 74 degrees F. For
larger beds, a separate, adjustable thermostat is
best.

In general use, thermostats have an operating range
between 30 and 120 degrees F.
Bury the remote temperature bulb beneath an inch of
soil midway between two
loops at the center of the bed. Don't allow the bulb
to contact the heat cable.
