reading alot in here about the gritty and 511 mix.it makes total sense to me.i think this mix will work very good for me.

my question is Al talks about the 511 mix all the time but all your pics has the gritty mix in them.my containers will be out all the time till the end of the season.it seems like both mixes will hold the water all the same,right?correct me if i am wrong.maybe someone that exeperice both mix could shed some light for me.
gritty mix is super for bonsai but it be good in nyc climate to be outside?should i opt for the 511 mix.i guss the qestion is what is the main difference.help plz

I use the 511 mix more since being on a roof, weight is an issue. The gritty mix lasts longer but weighs more. The 511 can be reused for up to 3 seasons. You will have to re-screen the bark to get the right size again. NYC climate is fine for outdoor use for either mix.

It's not easy finding the components for either mix in the city. If you find a good source for any of the components, please post.

5-1-1 is easier to make, lighter in weight, holds more moisture for Summer season gardening, and is more economical than many other pre-bagged mixes.

For tomatoes and peppers, I use the 5-1-1 almost exclusively.

I use the gritty mix for almost everything I expect to be in the same soil for 2 or more years - mostly all my houseplants, succulents, bonsai, and material I'm growing on as future bonsai. I use the 5:1:1 mix for things I expect to be in the same soil for 1 or 2 seasons only. That would be mostly veggies and mixed floral display containers, but some really vigorous perennial material (tropical hibiscus, datura/brugmansia ....) also get potted in the 5:1:1 mix.
