Adding stuff to Promix

Greetings...

Just wondering what other pro-mix fans do with the stuff - use it on its own, or mix in some compost etc.

Last year I was 100 % pro-mix, with 2 tablespoons of tomato-tone per container thrown into the mix.

This year I'm going with 75 % pro-mix, 25 % Leafro (composted leaves), and 4 tbs tomato-tone.
 
wow I thought more people would respond to this, I was looking forward to seeing all the different ways people use/mix pro mix
I dont do too much to it just mix in some compost and a little perlite,
 
i used pro-mix BX exclusively up until and including 2 gallon pots. now outside with the quantity of large pots I have to fill I mixed it with peat and tri/multi mix (primarily peat and compost) to see what results I get and try and make the BX last a bit longer. A bale runs out fast and I've spent enough on BX this season!

I have 2 BX's and an HP that I'll save for overwintering/next season. Never tried HP but I'm looking forward to it since it's high porosity.

For each 5 gallon bucket I mixed in 4 gallons of promix, 1/2 gallon of worm castings, and 1/2 gallon of extra perlite. After that, I just mixed in my nutrients (bone meal, kelp meal, greensand) and chucked my plants in. I think next year I am just going to use tomato tone for my nutrients and leave the rest of the mix the same.
 
I dont really do much as I add liquid nutes along the way -- this year I mixed about 1/8th to 1/4 cup of blood meal to each 5 gal pot. My Hatch peppers really took off with that mix so I began using it for others we will see
 
I mix in compost and/or aged manure for bigger plants, and for small seedlings I just like to add some extra perlite. The compost/manure livens up the mix with nutrients and beneficial microbes, and it feeds the soil which feeds the plants versus chemical nutes which are like candy feeding the plants directly but not helping the soil(usually the opposite)
 
I try to keep most of my nutes organic whether it is teas from castings or fish/kelp however natural fertilizer is mainly slow-release, many plants still need large boosts of nutrients at key times which the soil may not be able to provide, I just give it a bump every couple of weeks.

I've never had that problem with chiles personally, although I do occasionally use some 20-20-20 water soluble
I find chiles use very little nutrients, I've grown plants from start to finish with just well water

+1 - I know I sound like a broken record, but people use way too much fertilizer. And it does more harm than good. Look at the results Potawie gets, and for that matter, Hippy as well. (I think he just gives his babies worm tea)
 
This is the first year that I've tried using Pro-Mix HP so I can't report on any results. The only thing I've added so far is worm castings.
 
You all must remember that Pro-Mix BX has absolutely zero fertilizers in the mix( other than micro and macro nutrients) and needs some food to feed the plants occasionally. I like to add compost to the mix when first potting up and then once a month I will top dress with Espoma's Flower-Tone. I started with Pro-mix several years ago and now just add some new peat, compost, dolomitic lime and new perlite to my old potting mix.

Yes, I have been thinking that each of the twenty or so times I've read people here say that Promix contains starter fertilizer. Promix is actually about 85 % peat, and the rest is vermiculite, perlite, lime for pH balancing, etc. etc. - there is no fertilizer, it's just a growing medium. A really good growing medium.

Hence my initial question, which kicked off the thread.

I ended up blending in around 1/3 compost to 2/3 promix, with a healthy scoop of Tomato Tone, more than I've used previously. I think the peppers respond very well to Tomato Tone.
 
hmm.. i throw my coffee grounds on top of the potting soil i use... i'd be doing the same if i were using pro-mix.
my morning cup of coffee every single day quickly adds up to a lot of those.

it's also something that my grandmother's neighbors used to do a lot with their pepper and tomato plants, and from what i've been told, it used to have a noticeable impact in how they performed as compared to other plants in the neighborhood.
 
In my three gallon buckets I'm using a bunch of promix, about 5 handfuls of cow manure compost and 3 handfuls of mushroom compost.

The plants seem to be doing ok.

First year using the stuff, though, so I'm kinda just playing it by feel. I may have put too much in or not enough, I guess I'll find out.
 
I guess I misunderstood and didn't realize you wanted to know what fertilizers we were using too.

I found some Pro Mix "Outdoor Planting" mix that comes in 1 cu ft loose bags. It's got compost and the micro and macro stuff that everybody is into using now a days. I've been adding the 1 cu ft bag to my old mix at an eight to one ratio. I'll add it to the Pro Mix BX when I start using it.

I did some browsing at the hydro store yesterday, that place has anything and everything a gardener could ever want, and picked up a box of FoxFarms Fruit and Flower ferts. It's NPK is 5-8-4 and also contains all the mycorrhizae and bacterial nutes. It's added at a rate of a tablespoon to gallon of mix. I use it when I pot up and will be using it once a month or so as a top dressing.

I believe it does have a starter charge of micro and macro nutrients, but its interesting how they don't have to include nutrient ratios like most other products

Promix BX
Canadian Sphagnum Peat Moss
(80-85 % / vol.)

Dolomitic & Calcitic Limestone
(pH adjuster)

Endomycorrhize (Mycorise® Pro)

Macronutrients

Perlite — horticultural grade

Micronutrients

Vermiculite

Wetting Agent
 
Macronutrients (Nutrients that plants require in substantial doses) = nitrogen, phosphorus, potassium, calcium, sulfur and magnesium

Micronutrients (Nutrients needed in small amounts by plants) = iron, manganese, zinc, copper, molybdenum, boron and chlorine.

It surely would be nice to know the percentages.
 
Wow, that is really interesting....I never knew Promix had fertilizer in it, but now it makes sense: "macronutrients" = fertilizer. The quantity must be low, though, for them not to even bother telling us how much.

Actually, I did have a few plants last year in containers of Promix that were never provided any fertilizer for the entire season, and they grew fine. So there must be some nutritional value in that stuff.
