    its not too much of a secret, most nutrient companies targetting Cannabis (ie: Canna, Advanced nutrients, Humboldt) all have very similar NPK. Its just a bit harder to see since they may break it up into 2-part base and multiple products. You can look at the base nutrients to see.

    You can grow Cannabis with Miracle Grow if you want, or dirt and soil even, but the closer you get to a Cannabis type nutrient the better the plant will respond.

    According to who? You?

    Point me to YOUR research.

    So, I've done quite a bit of research on this at school (I've got access to all the good expensive databases), and commercial growers start out with a base hydro nutrient and add extra stuff that's crop specific (fruiting is different than leafy veg etc). The base nutrient works but doesn't yield as much, because it has everything necessary for the plants to grow but not in optimal concentrations.

    They also conduct water analysis of their feed water and change the formula to account for whatever is present in the water.

    Yeah I want to know too, I'm curious.

    Just about everything out there your going to have to add products as MC is more than just a base. A lot of these company's charge a premium if you want to explore beyond the basics. Even then this grow and bloom A and B is a joke. There is nothing wrong with a nutrient company making something specific to our plants but I take offense to them trying to gouge us.

    Its basic physiology of how plants work.

    If a plant needs 6 separate elements in certain amounts, and if you only give it 3, then it will still grow but will be held back a bit.
    Similar, if you give it all 6 elements, but in wrong amounts, then also it will be held back a bit.

    Think of a growing child, who needs 2000 calories a day to be healthy, if you only give it 1500 calories per day, the child will still be living but might not develop or grow as much. Similar, if you feed 2000 calories of just Coca-Cola or cheese, the child will have malnutrition and have problems.

    About NPK, we are using some ballpark of 2-1-3, as far as scientific backing for this, the best thing you could do is a bit of research about cannabis NPK, there is quite a lot of research about it, it goes back over 40 years (those hippies were pretty smart!) Different strains/conditions have slight variations in what they require exactly and we tried to cover all the bases with that, including coco growing.
    yeah, this is true. For commercial grows (think of like corn or wheat) the fertilizer they use are mega bulk type things like Urea, Ammonium Nitrate, Potash. These things are very cheap too, then they add some extra product to make it work better for their crop more specific.

    We have private researched that we used to design the formula, actually MEGA CROP is a descendant product from our old product Logic Grow and Logic Bloom (now discontinued, most people won't remember them!) and its been a design process going back about 6+ years.

    I don't have all the research in a published document which I think is what you are requesting. You can see all the formula result (we posted earlier) which shows MEGA CROP analysis sheet which is the final result. As a fun exercise, you could look on this site
    https://agr.wa.gov/PestFert/Fertilizers/FertDB/Product1.aspx?ltr=P
    You can check out lots of brands NPK analysis to see whats out there currently

    Dude, I'm not trying to break your balls but all the marketing fluff isn't necessary. You may have done some trials, but please don't call your research "scientific" until the details (including statistics) have been published.

    You have a product that has been tested by a variety of growers and received favorable reviews. This isn't scientific, but it's still good info. The fact that megacrop is also affordable is all you need to market it.

    I recommend that you don't talk about scientific research unless you are willing to share it. :roll:

    I'm not sure to be honest. another member here @cat of curiosity had the same issue as me with pH dropping out of range within 4 days. they were using RO water too. and a different brand of pH UP.

    my thoughts (and i'm no chemist) is that there are no buffers in pH up that will keep it stable. I did the same with pH down and it still drifted back up after a while in just RO water.

    Faster growth. Ability to use it on younger plants. Doesn't burn as easy.

    @Chunky Stool not sure what your beef is. May not be one but it sounds like it.

    I've always called bullshit on the cannabis specific thing. Mainly because of the price gouging.

    Its a good product in one part that is affordable.

    @GreenleafNutrients
    i'm doing a res change today to well water and MC.

    if my pH stays stable or drifts up (like @ChaosHunter ), then the issue is RO vs tap/well water and not pH up or down products. would you agree??

    i'll be posting my readings on your thread under advertisers about happy to be here at RIU

    My beef is marketing BS.
    When it comes to science, the guy talks the talk but doesn't walk the walk.

    I am surprised that I have to explain this to you. :roll:

    Don’t they adjust the ratios of NPK for the specific crop?

    Or at least vary the calcium nitrate?

    As I understand it the 2 main causes of iron deficiency are alkaline soil and out of balance minerals. Excess phosphorous causes iron deficiency.

    Other than difficulties with uptake I believe iron is in abundance in peat and compost already.

    Also present in well/tap water.

    But I am not an organic gardener and if really had an iron deficiency I would just use chealated iron supplement.

    I have heard to put a rusty old nail in the soil. But I don’t see how the iron would break down in time.

    It took me about five seconds to find out that Foliage-Pro is 0.05% Sulfur. The sheet says "Nutrient levels are ideal to achieve optimum plant growth but may be below levels to satisfy the labeling requirements of some state fertilizer laws." They list a reference, ”Mineral Nutrition of Higher Plants” by Horst Marschner- Second Edition 1995

    I can't say if your Mega Crop fertilizer is better than Miracle Grow but I'd say your knowledge is still lacking.

    Yes, and depending on the base solution the micros are different too. I don’t know that much about the testing processes yet, just that it’s done and it increases profitability directly (final yield, AND quality (no scorch, more flavonoids)) and indirectly (healthier plants are more disease and pest resistant).

    All of it relates to the law of the minimum.

    Thanks for the info! I didn't know that about excess phosphorous.
    Ever use heavy duty landscaping staples as anchors for tie downs? They rust & hold very well. The color of the soil changes around the staples and roots avoid them. Not sure about them providing soluble iron that the plant can use, but it makes repotting easier if you LST.

    I use those big black heavy duty paper clips and soft wire tie.

    I don’t think I want metal discoloring soil though.


    And iron is misdiagnosed a lot. It is one of the reasons bloom pk boosters yellow leaves so quickly.

    I know there is a trial out there that says too much nitrogen lowered thc in hemp but I like to feed balanced to the end. Just less as the plants need it.

    No one is complaining about potency. And I still get high every time.

    @whitebb2727 @GreenleafNutrients
    Sorry for being a dick.
    I've wasted a lot of money on products that were "made for cannabis" -- and even had cool hippie graphics. :dunce:
    So I'm just overly skeptical I suppose. (paranoid? o_O)
    Megacrop looks great and I would like to try it some day. I've already got a variety of nutes that I need to use. They are all good products I've had success with in the past. Jacks, plant marvel, Sea Grow, RAW, Technaflora, Dyna-Gro, Mills, GH, and probably a few more I can't remember. All good stuff.
    Don't even get me started on organic soil. I've got buckets of hydrated coco, bales of this and that, bat shit, bird shit, bug shit, etc.
    Three worm bins. A giant pile of recycled soil...

    I've gotta use what I've got. :?

    Sorry for being a dick. :eyesmoke:
