Has anyone tried replicating GH Flora Series?

thats still more then double, haifa or yara stuff. but i get it jacks is pretty good! i typed the jacks stuff into my npk calculator for my buddy recently and i think the vlaues are almost optimal. I worked out that. 1.08grams jacks 5-12-26 and 0.95gram of yara calcinit per liter of water would make close to my optimal recipe.
as for bottled nutrients just mix your own, its easy just involves som basic highschool math! :)

For example with this 2 part jacks recipie
For Part A: add 981ml of water and 189gram of calcinit together.
For Part B: add 978ml of water with 215grams of jacks 5-12-26 together.

thats your part a and part b. now these stock solutions you apply at 5ml per liter of water.
if you want the stock solution to last longer add sodium benzoate :)
for this recipie you need nothing else dont think about adding calmag. or pk boosters, they fuck up the ratio and result in less yield in my expreience. from clone to end of flower same feed.
I mix all my stock solutions at 1lb per gallon. Most instructions say to mix it more concentrated, but 1lb per gallon makes sure it all dissolves. I usually grow flood tables, but I’m always trying new techniques including aero, so I need a totally dissolved stock solution.

I only use jacks, calcium nitrate, and epsom salts in my grows. You’re right, all the booster crap usually just messes up the npk and micro ratios.

I don’t know if jacks tomato can be any cheaper than GH but it’s pretty easy to use for finding the right water quality and dilution at all stages.

I just full flooded with 927ppm. About 1ml/gal each of floramicro and cal mag by GH then the rest jacks tomato feed. It was a lucky guess cause I just did one 1/2tsp measuring spoon of each micro and CaMg, and 4 big scoops of h jacks in like maybe 8-10 liter cat litter jug.

I’m pretty confident that someone could use jacks tomato with any media and get great results without complicating things. Just one part fertilizer for entire lifespan.

In my case it really helps to have the one magical; balanced and complete component for obtaining the desired PPM levels. So jacks tomato is always the last ingredient I use to make my water the right solution for whatever stages of growth.


I found jacks tomato feED on a shelf in a feed and garden store and the guaranteed analysis seems like weED perfect!! So I use it with grow big or pure blend pro or neptunes or nectar or GH or General Organic or jacks 202020 or miracle grow or whatever people got going on. Jacks tomato in my opinion just that perfect one part food to hit the right run off ppm in a chelated recirculated or run off type agricultural watering process.


Even using biothrive bloom I was using jacks tomato because using more bio thrive would create a super low ph issue. Instead, I could use about half biothrive with FF micro and calmag for about 800 ppm and then tomato feED for the last 300-400ppm and get the right pH; somewhere between 5.9 and 6.2 when flooding large soil containers indoor.
