Come on guys, you're not even trying! Are these proven recipes? Commercial products don't count. I think it'd be a good idea to offer the proof, like "I've done 4 grows with this mix, no worries", or better still, GJ links. Don't mean to play mod, OP, but you repeated this once already. Just my ...

mr. hyde

my mix has basically been covered by brindie, but i can add that it is not a good idea to buy soil at dollar stores. i made this mistake once. butterfield farms and gardenscape soil mixed with perlite is no good at all.

I started out with just some pre-ferted stuff from home depot (50 lb)but overwatered and made the stuff extremely acidic.(3.5 to 3.0 pH)
got smart went out to the Sonoran desert and collected about half a trunk-full of dry wash and lightly vegged topsoil (ph 8.0 to 6.5), added 18 dry qts of vermeculite and mixed throughly.

pH between 6.5 and 5.5 depending on water content have not added any ferts but transplanted what was left of my garden into the resulting soil mix. wanted to try just straight desert topsoil, but just too alkaline and VERY DENSE and heavy (mostly sand and some silt)
so the mix:
50lb preferted bag soil
50 lb Sonoran desrt soil
18dry qts Vermeculite

How about we call this one Palo Verde mix?

Hey OP,

Now that it was broke up and explained alittle....if you have something in the finished thread about outdoor mixing...the water polymers should be brought up..imho.. because they really are useful in many outdoor situations...or even in some situations were there may be an un attended indoor...anyway...a year or two back..ButterflyDreams and I were playing with them....I tried cloning with them, germing...lol...all kinds of stoner things.....until BD suggested putting them in a glass and after they swell....to drop dye in them and watch the migration...lol...the wife threw them out when I strongly suggested filling her crystal vases with my new found colourful creation... ....one thing I can say tho, is that that they absorb nutes ..like if you just pour the crystals into a bucket...no soil....and mix up a batch up nutes and pour it in...they will absorb the nutes along with the water.....on the flip side....I wouldn't suggest using them in an indoor that is being regularly attended and cared for....because they also absorb anerorbic bacteria.

Say,
Bubba-Thanks fer the help. "PROVEN" is key. If ya haven't used yer recipe for an entire grow to prove it out. Yer not helping the purpose of this thread. It's ok if they use some commercial stuff in their mix. Many newbs just want to know what works and how to throw it all together in order to have a sucessful grow. However, others may want to be more scientific and go with home made organic matter and such. I agree that just posting a bag of commercial potting soil is not the intire mix!!
Quasi- Oky Doky on the water polymers...I think they would have a place in outdoor growing where the grower can't get to it often enough to keep up with water sched.
OP
