Cool, a yogi challenge! By chance, I have a few spare Finola seedlings which were put into soil March 2. I'll participate with those.
: Are we talking British Imperial fluid ounces or U.S. fluid ounces?
Because mine are in 150 gram yoghurt cups which is, at a density of 1.05 for yoghurt, 143 ml at soil/yoghurt level (not brimful) corresponding to 5.03 UK oz or 4.84 US oz. BTW 'ml' means 'millilitre', a metric volume
For those privileged ones not having to use conversion tables (like most of the world): 6 'generic' oz may be 170.5 ml or 177.4 ml, respectively.
Got to organise bigger yoghurt cups... as if I could win with a hemp variety LoL!
Now here's the pic @ day 4 post seeding.
