Good info guys, Thanks!
Yeah, I've done this a few times before, just never used the heat mats. When they come in, I'll measure them up and build a grow stand for each.
I was getting pretty heavy into this when Mom was alive. Always more fun with someone else.
I did jump the gun and picked up a heated starter kit from Menards. Has the same jump start mat as the one posted above. Seems to be working well. Have some Dill and Pickle seeds in it now. Wanted to test those first.
I've done the Ziploc baggie/paper towel trick with pelleted pepper seeds to get them going, except I initially put them on top of the light fixture for the heat source. Well, not the best temp control, but it worked. Kinda tough to get them out once the roots are taking hold in the paper towel. Maybe a not so loose fiber paper towel?
Once they germinated and were going, I put them in 3" Jiffy Pots and cooked them under the lights in the mini greenhouse for a while. That worked pretty decent.
I did the hardening thing by setting them outside in partial sun for a bit each day on the bottom of a couple 75 gallon holding tanks that were upside down.
They did quite well, along with the Anaheim Chilies in a 4'x8' raised bed.
One thing I like about the 3" Jiffy Pots is you can just drill a hole in the ground with one of these:
Cut the eye off and chuck it in a cordless drill. Works Great!!! Everyone around me that messes with gardens has one now. I have a bunch left, so doubt I'll run out anytime soon.
I think the addition of heat mats this year will a big plus.
As far as lighting, already have a number of options on hand. I've used the 6500K near full sunlight spectrum fluorescent in the past and think those work well, just ON/OFF tho.
I'm sitting at the table right now with a single CFL bulb overhead and am getting 5.47 foot-candles at roughly 5'. Knowing that distance from the light to the plant can have an effect, do you think by adjusting the intensity of the light, rather than having to move it will be of benefit?
Is there any way to determine the proper intensity in some measurable value like FC or LUX for proper plant growth? I can swap out the ballasts on my 4' x 6 bulb fixtures with ballasts that accept a 0-10V Analog input (dimmer ballast) and adjust it. Seems that just maybe easier.
