The six pack formula

[Coir]

You should not add potassium silicate to stock solutions!
I run two stock tanks at 200:1 ratios without having any problems. Have been for 25 years and never run into problems with having everything but Cano3 in one of them. Your hard water might be the issue if it's very high in Ca.

There is a lot ! Of ca in my water. I enjoy the si in my formula and see benifets in the heat. I have it deprecate from my three part. I don't use an ro in my stock for overhead reasons. I build my solutions base off my water test numbers. Separating into a three part, my Ksi and acid solves the problem with no floculation and no waisted water or extra materials to buy in the long run

Is the Ca and Mg in city water available to the plants? If it is, how much?

You need to have a water analysis done to determine available Ca and Mg in your specific water source.

changes every season. Our water table has been dropping dramatically for years

just curiouser what problems were you running into with putting Ksi in your stock solution? Iv always had it separate.

I have not personally added it to my stock solutions based on the advice of several manufacturers. Honestly, I do not even use it as I saw no benefit for the period I tested it side by side growing tomatoes commercially in coir.

This is a basic fertilizer recipe that has been around for longer than I have been alive. It's made up of basic chemicals that can usually be purchased at farm supplies store or possibly your local shop. These chemicals are the same as the ones used in many over priced fertilizers marketed towards us. Basically our medicine has an optimial diet. that diet is the NPK profile/rating of the nutrients you feed it. Not only does the six pack formula start off on a nearly optimal profile of 3-1-4-3-1 it allows you to fine tune it.

Now some of you may be wondering what NPK profile is or how to understand what 3-1-4-3-1 stands for and EVERYONE should go read this thread----->



The knowledge dropped in there is invaluable to us. so start there to get an understanding.

The six pack formula is made up of six ingredients

1.Calcium nitrate

2.Potassium sulfate

3.Potassium nitrate

4.Mono potassium phosphate

5.Magnesium sulfate(epsom salts)

6.Trace elements

These six ingredients mixed together in the given formula will give you a nutrient profile for veg of 3-1-4-3-1. I haven't done the bloom formula yet but will post its profile as well. the holidays are hell and this isn't really top of the list on the priorities list, but i will get it up.

I would work off the grams per litre section as that will be more precise.

Hey Tyler lol love the nameI know this is an old thread but I came across your formula and I'm gonna try it, what is the npk values for the grow and bloom solutions? Thanks:)

If I use the original 6 pack formula with RO water do I need to add any additional Cal/Mag???? I used this formula back in the mid 80's with great success.
