Hi,
I have followed the answers and you have recieved a lot of good advice.
One bit more you may consider and usually the big part of the problem.
I find unless you live in a hot and dry area with low humidity.
Is not to fill all the open spaces up in the mix.
Peanut shells are like mini sponges and hold a lot of water for a long time.
I have been through these type of mixes over the years and find my plants grow just as good on most occasions, better if I just stick to one medium. ie Coco nuggets by them self is perfect and same applies to bark.
Just use a size to suit the pot and type of plant, big fat type of roots I would use a more larger size that I would for small thin type of roots.
After all it is not a potting mix as such as you grow tomato's in but a medium to hold the developing roots and stabilize the plant.
also have the ability to hold a some water for a reasonable period
My bit to help.
Cheerio
Ron
