Cheers organic fanatics and all you mentors
I need your opinion on my situation. Currently Im gathering all the materials needed for a good soil mix.
So far I have:
Blood meal (N), rock phosphate (P), kelp meal (K), dolomit lime, Perlite and Mushroom compost (also wood ash, but some say thats bad...).
Im a little unsure what kind of spagnum to choose.
Whats available is swedish spagnum peat very similar to the Canadian flavour.
It comes in these kinds:
1) Unferted, "clean", low ph (~3.5-4.5) spagnum.
2) Ferted, low ph (~3.5-4.5) spagnum.
3) Ferted, mid ph (~6.2) spagnum.
I dont know the exact NPK values of the ferted one, but its probably mostly N and a little P and K.
Which one to choose and why?
I've been doing a lot of thinking, and I am willing to share my thoughts, but let me get your initial opinions first...
Two things I dont understand:
1) Why is recipe number 1 the same for both unferted Canadian Spagnum and ferted Pro Mix BX or HP / Sunshine Mixes? Wouldn't one end up with a more ferted mix if choosing ProMix/Sunshine or in my case ferted spagnum?
2) Why would one apply the same amount of dolomite lime to a spagnum mix thats pretty low in ph and to a Pro Mix / Sunshine Mix, thats ph'ed to around 6?
The two options Im leaning towards is:
1) 40% unferted spagnum (no Perlite, just clean spagnum), 40% Perlite, 20% Mushroom compost.
2) 50% ferted spagnum, 40% Perlite, 10% Mushroom compost.
What do you think? All inputs are more than welcome!
