Miracle Grow Hydroponics

    I was thinking on making a hydroponics system and was wondering if miracle gro would be good or ok to use in the water? I don't have any place near me that sells hydroponics nutes and I don't want to order them online. Is there any types of nutes that I could find at places like Walmart, Lowes, or Menards like miracle gro which would work in a hydroponics system?

    Thanks for the replies

    I have never tried it and probably never would but if your desperate google has tha answers. I know i have seen hydro recipes based on MG before.

    Good Luck

    Guess I'll try it and see what happens I have a couple of other nutes that I think I will throw in also. I'm thinking on using some lawn fertilizer 12-12-12 like 1 tsp to start with and I'm going to try a manure teabag using horse manure and alfalfa meal teabag in it to to make sure that they have plenty of food.

    Try to find Alaska brand nutrients if you can. I don't have experience with them, but I've seen them at the Hydro store.

    Lilly Miller -- Alaska Brand

    Then lo and behold, the local Walmart here actually carries these plus Superthrive and all kinds of other organic soil and soilless mediums. Guess we have a lot of need for those here...agriculturally speaking.

    If your Walmart doesn't carry them, go to your local Ace or other hardware store or gardening center. You'd be surprised what you can find when you look.

    Walmart also carries HO T5's and HPS bulbs.

    Good luck. Go Green...Grow.

    unknown you go by the ppm's for hydro and pH is extremely important. You will need a meter for both of these things. Hydro is very sensitive to increases in both, it's not like soil where you can just throw some organic stuff in there and hope it works.

    All miracle grow attempts end up failing.

    To grow hydro you must have micro nutrients
    that are not in Miracle grow.

    That is why you need "hydro nutes".

    Your plant will quickly die,
    when you start to flower.

    try making your own tea from worm castings,blood meal,bone meal and whatever else you can find. since I started using this in my Hydro Hempy buckets I have had explosive growth and alot cheaper than other nutes, plus no mail order(for the paranoid pot heads like me lol).

    What media are you using in the HBs?

    Celticman Well-Known Member

    Use Schultz Bloom Plus as your bloom (it's 10-54-10, with micro's). Use thier regular plant food as your veg.
    Make sure you get a ppm meter and a ph meter.
    BTW- all the above can be found at your nieghborhood Menard's.
    and it says "for most hydroponic systems use 2-3tsp. per 10 gallons" right on it.

    You don't have to use $$$ nutes to produce huge dense buds. Just feed your plants what they need, and that is the correct nutes..... not necessarally a certain brand or product.

    Why don't you join our Hydro Nutrient Challenge?

    And then you can prove that statement.

    WOW!! 54 thats insane. I think I'll give that a try! Ive been using Ace hardware brand. Exactly the same as MG. And just about every other water salouble chemical fertalizer. I use it for seeds in dirt. After meeting some one who has been growing with MG in both "dirt" and hydro, i belive i'm gona give it a try. From what he was telling me using MG in a hydro system is quicker than dirt, and has a higher yeild. This guy has been growing like this longer than I have been alive. I guess there wasnt a huge market 40 years ago so he made due with MG.

    I use the horse manure, I get a panty hose crush the manuer put it in the foot section and tie it closed. I put a small rock in there and it sinks to the bottom. Use only old horse crap has to be white, 1/8 th cup per gallon and I change it out everytime I change out the res. I clean the res every ten days during veg and every 7 days during flower. Great stuff, dont use cow manuer use horse. Good luck

    miracle grow is no good because it supplies a large amount of its nitrogen as urea it is designed for soil
    also it lacks sufficient secondary and trace elements
    it is possible to buy raw hydro nutrients in bulk direct from suppliers if you want to be buying 25-50 kg sacks of A+B at a time

    it is also possible to find regular plant foods that does supply nitrogen as nitrates, calcium , potassium nitrates etc
    plat food designed for orchids often will use nitrates directly instead of urea because orchids need food to be instantly available, still even orchid food is designed for soil and would lack trace elements which are abundant in soil , you would still need to add Epsom salts cal mag etc,
    avoid any soil designed food that contains urea in hydroponics, urea needs to be broken down by microbes that would be present in soil, but are not present in hydro

    using a liquid hydro food like canna / vitalink / dutch master etc etc makes a great deal of sense and avoids many potential problems
    although i have not used 1 part foods myself like ionic grow/blow, i have seen good results from the most basic designed HYDRO foods
    trying to save money by using soil designed foods in hydro is not a wise move

    peace :)

    cannabineer Ursus marijanus

    Two things to keep in mind.
    1) Miracle Gro uses urea nitrogen. this will not show up on a TDS meter.
    2) You will be lacking the "unspoken macros": calcium, magnesium, sulfur, as well as some micros.
    So to make it work you'll need to supplement those ions. Might as well mix a complete salt fert at that point, unless it's a novelty grow. cn

    Dyna gro! Its cheap & easy (1 part) and I believe it's probably one of the only no-nonsense options our there. I only wish I would've tried it sooner. Although I suppose it doesn't get any cheaper than horsie poo, lol.

    Why do Cannabis cultivators still use miracle grow? I understand using it when there weren't too many fertilizers available but most of the nutrients you pick up at your local hydro shop today were tested and manufactured for Cannabis cultivation, meaning they designed this shit specifically for marijuana! If you still use miracle grow successfully then " good for you!" but I'd rather just buy some soil or hydro nutes that were designed to grow cannabis.

    Miracle gro will not work with hydroponics because the nutrients are in the wrong form. If you want cheap, high quality, no frills hydroponic fertilizer buy in bulk from a professional outfit like CropKing: http://www.cropking.com/HydroponicS...64_265&zenid=8b3ee8bc112a7eed58bdca0124466fdc

    theres someone someone who knows :D what he's talking about. I use fertilizers in bulk parts + micro nutes mix. nitrates only for hydro, my mixture is made of the following:
    calcium nitrate, potassium nitrate, mono-potassium phosphate, magnesium sulfate(epsom salt), trace element mix, and phosphoric acid. Results are awesome, and I perfectly control feeding.
    as for Miracle Grow, I actually tried it on my very first grow, it was bad, plants were unhappy until i got hydroponic fertilizers...
