    Just for fun...

    GenHydro 3-part for Dummies

    1/ Delete the Grow (green) bottle.
    (See also: "Lucas Formula")Help! Ppm's dropping a lot between res change

    2/ 6ml micro, 9ml bloom per gallon @ 6.0-6.2ph
    You feed this in veg, and flower, too. DWC, coco, ebb/flow tables, whatever. Easy. As. Fuck.

    A 10 week cycle:
    (Assuming your water is spring water @ .1EC or EC 0 if RO.)
    ****If RO water is used, add 3ml/gallon CalMag throughout entire grow UNTIL end of week 8. If using spring water in coco, use CalMag in the first month of veg, then delete.

    Week 1-4:
    6ml micro/9ml bloom, EC will be 1.2-1.3
    (Fuck "ppm" as a measurement, it's for rookies) Help! Ppm's dropping a lot between res change

    Week 5:
    6ml micro/9ml bloom + kool bloom POWDER @ 1/4 tsp/gal. EC will be 1.3-1.4, ph should always(!) be 6.0-6.2

    Week 6:
    6ml micro/9ml bloom

    Week 7 & Week 8:
    6ml micro/9ml bloom + LIQUID kool bloom @ 10ml/gal in coco. ---> 5ml/gallon in DWC/buckets/tables.
    EC @ 1.7-1.8 in coco, about 1.6 in DWC etc.

    Week 9:
    9ml bloom ONLY/gallon
    (This tapers nutes off & starts the plant flushing)

    Week 10:
    Pure water at 6.2ph

    You might try your local library. I was wandering through mine way back in the early- or mid-'80s and found a book on hydroponics. It wasn't huge, and the "pictures" were mostly just line drawings. But it even went into ordering the separate elements/minerals and mixing up your own hydroponic nutrients. There aren't many recent books that seem to cover such things. And that's a shame, because the related information - such as how adding some things in certain forms can cause other things to precipitate out of solution - can be very useful, even if one never intends to mix up his/her own nutrients from the individual components. And this book was published... in 1972 .

    I guess it makes sense that (some small number of) books have been getting published on the subject of hydroponics for decades. After all, the practice of using hydroponic growing methods has been around since... How long ago did the Hanging Gardens of Babylon exist, lol?

    Thanks for sharing that Skunk. I have saved it in my formulary for further consideration.

    Easy is a good thing, but it's not the only thing. Those who are willing to fuss with concentrations a little more should be able to get higher yields. It would be interesting to do a side-by-side grow test.

    I agree that EC makes better sense, but so does the metric system. Just as if you happen to be living in one of the backward countries that still uses imperial units, you'll communicate better in pounds and inches, when you're on a forum that uses mostly PPM, it makes sense to use that. And unlike converting between imperial and metric, you can convert between EC and PPM with one simple mathematical operation. Easy. As. Fuck.

    Oh, it's much worse than that. Some don't what date Independence Day falls on, and yesterday there was this:

    This NPR/PBS NewsHour/Marist Poll Reports:
    While 77% of residents nationally correctly cite Great Britain as the country from which the United States declared its independence, nearly one in four, 23%, either mention another country, 8%, or are unsure, 15%.

    Thirteen other countries get tabbed as the country from which the United States gained its independence. A scattering of people mention France, Mexico, and Germany among the longer list of countries. At least one person surveyed mentioned Afghanistan, Brazil, Canada, China, Columbia, Denmark, Italy, Japan, Panama, or Russia.”

    Help! Ppm's dropping a lot between res changeI'd disagree . In my garden(s) the 6/9 ratio has proven to work indefinitely. I've never seen a P issue in veg, in decades (plural) using it, even with older, 6' mothers in pots.
    As to long veg periods, other than if running 12' tall indica trees under Gavita DE's in 60 gallon pots, I can't see running a long veg time for any configurations I'm into, (and after thinking about it some more I can't think of good reasons to long-veg for much of any reason.)Help!

    Metric? Imperial? Only in the cannabis world do we use "grams" and "ounces" in the same sentence .

    For purposes of this discussion, "PPM" is just a number that has been arrived at through a (simple) calculation. It's not like we count... one... two... three... ... ... 646... 647. There are 647 parts per million of dissolved solids in this sample. Whew. Lol. My buddy who used to work in a municipal wastewater treatment plant didn't even do that - and he had to remove the liquid from the samples and then weigh them (on the single most accurate scale that I have ever seen). The meter also doesn't do that - even if it is a "PPM meter." It's like when a person has their vehicle tested on a dynamometer. They come away with a slip of paper that states how many horsepower their engine produced (mine stated "611"). But the device never measured horsepower in the first place; it measured the torque, then did a calculation. BtW, I knew (vaguely) a guy that managed to get a piece of paper that said his car was beyond the capability of the device, as it only measured torque up to 1,200 ft. lbs. (highly modified and twin turbocharged 1987 Buick Grand National v-6 monster, lol, and IIRC, one of the mods was trading the 231 cubic inch block for an old stage II Bush Grand National Buick V6... 274 ci, I think).

    Sorry, rambling. That's how you can tell no one else is using my account, I guess.

    So all such meters are actually measuring EC (electrical conductivity), regardless of what they are called or what units they display. And the EC is determined by the salt content. Funny thing is, different salts have different EC. IOW, if you had two one-liter beakers of distilled water, and you added sufficient (for example) potassium chloride to the first to bring its TDS content up to 1,000 parts per million... and you added enough sodium chloride to the other one to bring its TDS content up to 1,000 parts per million... If you then stuck your meter into each one, you'd get different readings. So none of them are going to give you an accurate TDS.

    It IS helpful that a lot of nutrient companies will give EC recommendations for their specific products, so actually knowing how many PPM that equates to is not necessary. And, obviously, if your reading is lower today than it was yesterday, you know that the plants have been consuming nutrients. The meters are just incapable of telling the user WHICH specific nutrients (Calcium? Nitrogen? Molybdenum, lol?)

    If using a "PPM" meter instead of an EC meter, it is helpful to know which of the THREE possible conversion factors it uses.

    Wow, just... wow. I didn't even realize that 23% of our population were politicians. But, seriously, that's so far past "pretty bad" that deplorable doesn't even cover it. I know that you cannot force a kid to learn while in school - but if my kid graduated not knowing such a simple fact, I'd be looking to sue the local board of education along with the principals of the schools he/she had gone to and every teacher that he/she was (supposedly) taught by. Or else they'd be dragging me out of the next board meeting in handcuffs even before the ambulances (plural) arrived.

    I've ran Lucas in the past using just Flora Nova bloom and had decent results. I now utilize GH 3 part along with mycorizae. Not very scientific but I use their directions except first few weeks that are at 50%
    As to Independence Day or The 4th of July they are just names given to the greatest experiment consisting of excessive freedoms, the Constitution, Declaration of Independence, the Pursuit of happiness, and capitalism. All wonderful ideas that created the country that was once and still is the envy of most of the world. I have ink that consists of an American flag along with many other patriotic yet also anti tyrannical tatts

    I've noticed that when using GH 3 part Flora series nutrients that the EC measured in µS is always exactly 2X the PPM value.

    How is that working for you? Can you observe the mycorrhizae colonizing the root zone, and thriving when being fed GH nutrients? I've used them in soil grows and never given it a second thought, but it was my understanding - which could be incorrect, for all I know - that this type of life feeds by breaking down nutrients that are NOT in a form that the plant can use, and then excreting(?), as a waste product, nutrients which are in a form that the plants can directly utilize. But nutrients such as General Hydroponics Flora are already in a form that the plants can use, so... IDK?

    Sure. But if you call it "Independence Day," it might cause someone to think about something besides fireworks and hot dogs. Or... maybe not.

    BtW, "pursuit of happiness." Most definitely not the same thing as "happiness." About 92% of the population does not understand the distinction, methinks.

    I don't have patriotic tattoos. But I do have a flag outside, at least. I'm probably the only one in my neighborhood who brings it in at night (since I do not have a spotlight to shine on it). So some days I forget to stick it back out there. Some of my neighbors probably think I'm a bit odd. <SHRUGS> But most of them undoubtedly know that I'm a great deal... odd .

    I have heard it said that democracy - or a representative republic, which is what we have - is not the best form of government, merely the best form of government that we have come up with so far. Makes sense to me.

    That's why I capitalized the P in pursuit. It's not a guarantee. It's up to the individual to make or break the opportunities given thru freedom. Today a large percentage of the population has been dominated by socialist policy to the detriment of our republic.
    That which you subsidize you will get more of... and I fear this apathy is destroying our once great nation. Public education for the most part has done exactly what the socialist craves... Creating a populous of ignorant needy lemmings who live at the whims of the government and the taxpayers
