New DIY Nutrient Thread

[LurchLurkin]

Just going to mentioned that Nitrogen is generally deficient in almost every grow. If you were to grow two clone plants next to each other in the EXACT same soil/soil-less medium with the light equally distributed you could see if this is the case. Provide one with your regular nutrient mix and lightly chlorinated water. Provide the other with your regular nutrient mix in unchlorinated water innoculated with nitrogen fixing bacteria and some extra urea.

If the urea plant grows better then you're lacking in nitrogen.

I don't buy the "grow and bloom" mix thing and I don't buy into cutting out/down of nitrogen in flower or flushing. Just need to properly cure and dry your stuff.

Totally agree, had better results running 1.6:1:2.6, NPK ratio through the whole run, right to the end. But as I mentioned earlier, I am seeing better than baseline results with the 1:3:2 boost added at week two?
Would like to be able to manipulate the ratios better (more N sounds like) when I get the stock solutions made.
Been reading this book,very helpful: http://www.amazon.com/Hydroponics-Practical-Guide-Soilless-Grower/dp/0849331676/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1411922929&sr=1-1-catcorr&keywords=hydroponics+benton+jones

This thread is a prime example of how bro science works lol.

Grow organic and leave all this foolishness behind.

Heres some DIY organic nutrient.

Lacto bacillus

Aact
Sst
Botanicals

Just to name a few

Organics is the same thing just less efficient with bacteria to make it slightly more efficient. This isn't bro science and you obviously are a bro scientist because I highly doubt you've read any scientific peer reviewed articles on hydroponic / aeroponic horticulture or you wouldn't be of that opinion. Bacteria just change urea and ammonium to the more easily absorbed nitrate and some can even fix nitrogen from the air. If you provide enough nitrates chemically then the bacteria actually form a parasitic relationship with the plant instead of a symbiotic and can hurt your yield.

Sounds like bro science to me. Im sure theres plenty of research on why and how this bro science works, reguardless its pointless and un sustainable. Ive heard arguements like what u just said, at the end of the day, its unsustainable, and WACK quality chem weed.

Lol, "organics is the same thing but less efficient" let me geuss, your one of them chemi growers that thinks your yield and quality is better then organics? The only thingi can think of that chemi grows have over organics is speed of growth. This however i would argue is bad, faster growth means the plant has no immune system to fight pest and disease, this adding to the problem of more chemi in form of pesticides and fungicides.

Bring your " scientific" bro science on. Bro

Your organic voodoo is bro science, but we don't go over to the organics section to hate. This thread was made specifically to talk about hydroponic DIY nutrient recipes and stock solution preparation.

At least take a little bit of time to understand what we're doing before ignorantly claiming what we're doing is "unscientific".

This isn't even science for me anymore. We're just feeding our plants in the most practical way. I've been doing it this way for about 5 years now.

Before I had hydrobuddy, I had my own calculator written in excel, and before that, I did all the molar equations by hand. Hydrobuddy's calculations are spot on and the interface is nicer than my own calculator, so I abandoned mine and switched over to using hydrobuddy for everything.

It's been extremely convenient and has been saving a ton of money over the years.

Using raw salts is actually a lot cheaper, easier, and has more consistent results than using organics like supersoil mixes.

I'm also of the opinion that the quality of the finished product is consistently better if everything is done right.

You should just leave out potassium sulfate all together. There's really no purpose to it unless you're purposefully trying to boost sulfate levels through the roof.

You should get enough of your potassium from KNO3 and KH2PO4 and KOH alone.

KNO3 is more of a potassium source than a nitrate source, by mass at least.

I got a free 50# bag of mono potasium phosphate and was thinking of doing a 2-part with some potasium sulphate and calnit. Would adding the micros as a separate 3rd part work?
Thanks

 

[chandi]

"bro science"? stupid.

Got it, no potassium phosphate, thanks; looking at potassium nitrate instead.
Also making a custom substance selection on hydrobuddy for the micro package and trying to get right ratios for either the fatman bloom recirc recipe or maybe just the straight hoagland.

On a side note: 3:1:2 is also mentioned in Ed Rosenthal' book.
