Mix recommendations for potting up seedlings?
I have some pepper and tomato seedlings that are due for potting up into 18oz cups. I started them in Ferry Morse organic seed starter mix, but not certain what to use for the next step. I picked up some ingredients today, but still haven't found any good partially composted pine bark for 5:1:1 mix.
Here's what I have on hand:
- Bale of compressed Sphagnum Peat
- Big bag of Vermiculite
- Small bag of Pearlite
- Small quantity of Reptibark (which was really expensive)
- Miracle Grow Potting Mix
- Lowes Sta-Green Potting Mix
- Bag of Gran-i-Grit
- Bag of Pulverized garden lime
I was thinking of trying 7:2:1 peat (wet), vermiculite, perlite which should be similar to Pro Mix BX (recipe courtesy of EngineeredGarden), but I'm open to suggestions.
These are being grown under shop light inside at regular room temps. I haven't figured out a good way to give the tomatoes cold treatment yet.
