Yes, I will not be the only one contributing content to the site. . The most advanced testing is going on in the Netherlands and not with cannabis plants.Firstly, thank you guys for throwing up some really good info-and quickly as well. Second, I really want to jump in and start with some questions, as well as some other things I discovered recently, but I'm just dog ass tired. I am very grateful, and my interests have peaked even more concerning the sap ph testing, and can't wait to check out some more info on it. Leadsled, I'm very interested-and YES that helped big time-will be following your journey through the brix and sap testing and research. Is the website you linked your own, or are you contributing content? Either way I'm going to check it out in the morning, as well as look into some of the info you presented. Great stuff. And I am very interested to see where the research leads. Have many questions forming already, but need a few winks before it becomes coherent, and hopefully I haven't ranted or rather rambled on too much or been typing word salad lol. Again, thanks to both of you, and I'll definitely be keeping an eye out. Peace, talk in the morning.
No, that is not entirely correct. You can use organic materials on a conventional crop but not vice versa.Oh, and one last thing concerning the method of growing and brix. That did clear it up for me, was just unsure at the start as I had only heard the soil guys mention it. And obviously there would have to be slight changes in the forms of compounds used in soil, and the compounds or delivary method in something like Aero, or DWC. But thank you for clearing that up again. Until next time...
In addition to brix testing, You can also use sap ph to determine what element is lacking.

Few examples:
Below 6.4 lack of a cation, above 6.4 lack of an anion.
Since Potassium is mobile. We can also test the sap for potassium.
If potassium is less tha 10% of the value of the upper leaves. The plant is robbing K form itself and time to apply K.
Can be done for a conventional (hydro dwc rockwool etc) or organic/regenerative/biological/ecodynamic no till/what ever the fuck style grower.For some growers it can be the tail that wags the dog.
That way you can "ask the plant" what is needed and then make educated fertilizing decisions.
For example. Test brix, Do a foliar spray. Then test one hour later and see if brix was raised.
Will be posting more info on various websites as well as on the www.plantbrix.com website when launches.
Going to review and test different products to see how they work at raising brix.
I have experience using the meters. Also teach farmers how to use them. Amazing stuff.
Sap testing can help to see a potential problem 4-6 weeks before you get a visual indication of a plant nutritional issue.
Hope that helps.
So the SAP ph test actually tells the element percentage? That has exceptional uses and I'm surprised that more people aren't using them, and aren't using them in addition to the brix refractometers. VERY helpful info, and very appreciative. Going to order both soon.In addition to brix testing, You can also use sap ph to determine what element is lacking.

I'd be interested as well. Is this something that comes from the tester?Mind if I ask the title of the book this image is from? It looks like something I should read.
Interesting. I wonder what its pulling that would drop it like that. And I'd be very interested to see if after you harvest the numbers change again-or rather how they change. Thx for posting.Small update, after 3 days of flush with Clearex, Brix raised up to 12. Now I'm just using distilled water and brix is 8.
Very interesting. I'm going to have to read up more. Thank you for taking the time to post.Yes, I will not be the only one contributing content to the site. . The most advanced testing is going on in the Netherlands and not with cannabis plants.
Shame than people get the blinders on and get the FALSE impression that hydro is some miracle growing technique.
It is good for the hydro business and for people to make an excess of money off you.
Weak and sick plants will always need help, so then you are sold pesticides which make the problem worse.
More money for the dro shop.
The pesticides make the plant weaker, then when you use water soluble ions, the plant then has to use another 30% of its energy to convert the water soluble ions into a form it can use.
Nitrate makes plants grow fast but they are weak and sick with lots of water in the cells and the cell walls are thin. The free nitrates in the sap is a calling card for pests and diseases.
Look at the products for hydro. What are they based on. Nitrate. Many pesticides are either nitrate or chloride based. Calcium nitrate is used in the nutrients or other ions combined with nitrate.
Hard to increase the calcium without increasing the nitrate.
I worked with a hydro grower that was in denial of these facts. Hires me to fix the problem, but then wants to ignore the fact he can not get in a run without pests or diseases.
Consistently gets mold, loses whole rooms to seeded crops and yet thinks all this science is "books not real life".
While continue to fail until you wake up.
That is why you keep seeing soil mentioned. If you want to grow the highest grade crops it is not going to happen with your current methods.
No, that is not entirely correct. You can use organic materials on a conventional crop but not vice versa.
DEFINITION: "conventional" grower --- one who uses *materials*
prohibited by organic certification programs (since by that criterion
alone (s)he can be denied certification).
1) There is nothing that prohibits a conventional grower from using
some or all of the techniques commonly attributed to (but rarely
employed by) "organic" farmers. Such as good rotations, green manures,
compost, refugia for beneficial insects, etc, etc.
2) There is nothing that prohibits a conventional grower from using
some or all of the slowly available mineral nutrients commonly
attributed to (but rarely employed in) "organic" production. Such as
rock phosphate, sul-po-mag, gypsum, etc. etc.
3) Combine 1 and 2 with judicious use of carefully selected chemical
fertilisers (such as ammonium sulphate, mono-ammonium phosphate,
potassium chloride and micronutrients) along with judicious use of
carefully selected chemical pesticides (such as Imidan, Roundup, and
assorted fungicides).
I would say that with such a system the conventional grower will
harvest a better *quality* product than the vast majority of organic
growers who, in their stubborn infatuation with materials issues, may
get it right about not using "chemicals" but generally miss the boat on
soil building, mineral nutrients, organic matter management, nitrogen
fixation, understanding the weed community .... and on and on.
If most organic growers would do what the industry publicity likes to
say they do (but too often don't), we wouldn't be having this
discussion. Conventional produce farmers are starting to figure this
one out, and if the organic people don't get their $#|^ together pretty
soon, they're going to wake up one spring and wonder where their
customers went.
