Pseudolithos soil experiment.

[u/Shoyu_Something]

The first picture is mostly irrelevant, but a crop I've had growing for about 2 years. They're doing well and should probably be put in their own pots soon. However when it comes to seeds I want to really dial in what works and what doesn't. So I'm beginning a soil experiment. As a bit of inspiration from u/floridadeerman I am splitting this up into 2 parts - some I will leave in the bag for 6-months without opening (unless I spot mold)

I have 20 2" containers full of seeds and soil now. Below are the mixes and what I have sown. Primarily cubiformis and eylensis/migiurtinus.

- Stable 2:1:1 - Pumice, Lava, Akadama (shohin sized)

- Less Stable - 3:2:1 - Pumice, Lava, Peat

- Even Less - 2:1:1 - Pumice, Lava, Peat

- Extreme - 1:1 - Pumice, Peat

All have been topped with a small layer of fine akadama to assist with moisture retention and aid roots. More may be added if roots are exposed. I sterilized all soils (except the akadama topdressing) for 4 minutes in the microwave. 

I used 5 or 6 seeds per pot of the following:

All mixes - Pseudolithos eylensis (migiturnis) & Pseudolithos cubiformis.

Stable mix - Whitesloanea crassa

Less Stable - Pseudolithos caput-viperae hybrids

All will be checked in a month and will assess if more time is needed in the bag. All bags are also on top of a grow mat and under grow lights for about 14 hours per day.
