I thought I would ask here as I bought too much bark to make the 5:1:1 mix. I need to fill up my existing greenhouse trays where the tomatoes will go and thought I'd mix in some bark. Anyone know if that will be a problem or not? How much would you suggest to add to general soil & compost? Trying to save from going back and spending more on soil as well.

Oh also what about sweet peppers. Do they like the 5:1:1 mix. I'm a total newbie (doing it the proper way this year with good results though thanks to all of you) so any advice I'd love. Thanks!
