I need some reading material. What is everyone's strategies for seed mix? Straight jiffy til it goes in the ground, jiffy with a sprinkle of worm castings? Maybe a touch of your own gardens soil? What has given everyone their happiest seedlings?

This year I am using 50-50 mix of Jiffy (sphagnum moss and vermiculite) and Burpee (coir and perlite) In the bottom 2/3 of the 5" peat pout I add a tiny bit of Jones Organic tomato food for the beneficial bacteria, and a bit of Wallace Mycorrhizae. The top third is just the 50-50 mix without any additions. When I move them to bigger pots, I will use Miracle Gro potting soil with the Jobes and Mycorrhizae added.

Promix in grow bags. 3 or 5 gallon. Its holds together when transplanting.

I have some test seeds going right now with two plants in each of jiffy, miracle gro, and black gold. The plants in the jiffy mix are short and stalky and the ones in the other soils are a bit lanky all plant are under the same grow light. I have always used the jiffy mix in 5 inch peat pots until first leaf starts to pop out and then into two gallon bags or pots with fox farms potting soil. Do some test and see what works for you.

Seems everyone pots up or starts in larger bag or pot. What point/stage of growth does everyone like to get in the ground? Is it feasible to go from a 5in peat into ground without being pot bound?

I start mine in 12 ounce clear plastic cups with promix bx. I use the clear plastic so i can see the root system Lots of times you see roots before the seed pops up. I then retransplant to larger containers with a mix of promix and garden soil. Give the leaves a short time to develop and transplant to garden area. Cover your cups with plastic wrap. wrap to retain proper moisture.

On average, I'm in the pot (2 or 3 gal bags the last couple years) for 2 - 2.5 weeks. Ideally, I'd like to go with smaller pots and quicker time to hit the ground, but you never know with the weather here.

5 inch peat is that about a quart? Might be ok one week in that size. I think about two weeks in a gallon pot. Clear plastic would be helpful but for me when the first true leaf is fully grown thats when its done being in a gallon size pot.

Mine are in Jiffy they look great I mixed mychorrhizea in with the mix. I hardly ever hold them for long periods and they go in the patch when the first true leaf is the size of a quarter

Still have two feet of snow on the ground I have to start plants a month before they go outside.

I grow in 6 inch peat pots, with pro-mix in them. This lasts about, 2 weeks I think.

Great stuff guys, only about a dozen seeds in my stash they'll probably all get planted with slightly different strategies, maybe I'll be able to help a newbie next season.
