    What nutrient line should I be using in a hydro set up? What are you rockin?

    40-50 gallon water changes
    inexpensive
    excellent quality
    excellent results
    ebb and flow
    hydroton
    r.o. water, can add some tap if needed
    ease of use (not that it matters i guess)

    Is there a powder nutrient I can/should be using in my hydro setup?
    Doesn't really have to be a complete line from a manufacture. I can mix manufacturers products if needed.
    TIA

    Look into the Jack’s 3-2-1 system, I would say. It is very popular.
    Personally, I run Oasis Hydro 4-1-4 (same company as Jack’s) and add 200-300ppm of MKP per gallon in flower.

    I just bought 5lbs each of 4-20-39

    and the Calcium Nitrate 15.5 -0-0

    Will buy Magnesium Sulphate locally, and order Mono Potassium Phosphate next week.

    My buddy has used this company for 20 years, but the Weed Formula hasn't been out that long. Long enough, but this is a good company.

    Smoke you been running this setup? you get good results? yield/ flavor? If you do run this you go by the recipe posted in the hydro-gardens website?

    ........................................................

    Thinking about pulling the trigger and doing this. Those four things is all I need? Nothing else.

    No Mono Potassium Phosphate after week four?

    My mix is very similar to that, in the final analysis, sounds like.
    I don’t always push the P as hard as I am guessing they do, but sometimes I do end up at about 4-6-8 toward harvest.
    I run Monopotassium Phosphate (MKP) in increasing amounts through flower, depending on the strains I am working.

    You dont need it but i bought it because i wanted every thing on the burchet(sp) feed chart

    I have a grow going now and it is my first run with it so far im very pleased.

    Super easy to work with but you need a scale.

    I havent finished a full run yet but im in week 5 of flower now

    I actually am just using the feed chart as a guide

    Cause its very concentrated if you follow the recipe ;)

    I am trying to run it on some seedlings i have going .

    But im not use to a full synthetic nutrient
    So i have never really gone too far over 1000 ppm.

    And their feed chart has you hitting a 1000ppm
    Pretty fast

    I gota run out but I'll be back later

    I like the feeding schedule, looks pretty legit to me, and it has good endorsements from everyone I have talked to who uses it,
    Do it!

    Might just be my set up but its on the hot side for me following the recipe lol

    I use the guide for the ratios to use for the different salts but so far i really like it


    The fact that it's clear ish is a huge bonus in rdwc:)

    Well besides this or that I think i've figured out what I have been doing wrong. So I can fix those things but one of them is I think i havn't been feeding enough in flower at about 1100ppms max in full flower. I dont think that is enough anymore. So that's why I want a cheaper nutrient so I can use more to get higher ppms and not have it cost me a bunch.

    So im gunna get the nutes and use the chart as a guide and just go by ppms start at about 400 for little guys and 700 ppms for veg and bump up each week through flower starting at about 900ppms and finish at about 1600ppms for like week 6 then back it down the last 2-3 weeks.

    Thanks for the heads up on the nutrients.

    It took me 36 hours to figure out was mpk was. I have always just gone by pk boost which for me is moab I get at the local store but thats 30 for a half pound when I can get it oniline at 15 for 5 pounds from the website that jimi told me.

    thanks for the info

    Sounds like a good product line for sure. How “hot” a mix is depends on a lot of factors, clearly, including grow method and strain being grown. I have no doubt that would be a bit hot for some cases.

    Sounds like a plan

    I was going to say a meter will help but you got that covered:)

    So far its cheap, high quality, fully soluble, clear (ish).

    So far im enjoying it but will know for sure how i like it after this 5 pounds is getting low.


    One thing i will add is most nutrients ph swing from 5.8 -6.3

    This stuff goes backwards it swings down from 6.4 to 5.?

    I spent the first few weeks wondering why my ph was dropping hella fast.

    Now i know lol set it high and it goes down.

    Whichnis actually badass as when you top up it brings the ph back up works awsome so far.

    I havevent been able to fry a seedling to bad with it either ;)

    Oh yea it does have a somewhat unique odor
    That i think will work well with weed

    As i have found every nutrient imparts a certain flavor

    Well see how it is in a few weeks come harvest.

    But i think its a reputable company because they have been going since the 60s and for a small company to be around that long is doing somthing right.

    You use the same amount of the mix as calcium nitrate? I'm curious about your ratios.

    I've been running Chem Gro 5-11-26 for many years now, also mostly in RDWC.

    Yes, 4-20-39 is mixed at the same rate as the 15.5 - 0 - 0 Calcium Nitrate.

    So a 1:1 ratio, cool.

    How much mag sulfate?

    60% by weight.

    Say it takes 100 Grams each of 4 - 20-39/Calcium Nitrate per 100 Gallons Water

    It takes 60 grams for MG Sulfate
