      I’m first time grower indoor what should I use that isn’t so difficult to follow but will have excellent results any help will do , I’ve been reading the comments up there I just need what’s best for indoor beginner .
      Thank you

    • Mary Jane Farmer March 28, 2018 at 6:42 pm

      As you’re a beginner, I’m assuming you’re going with a soil grow(?).

      So, first off, be sure you’re getting nutes formulated for soil rather than for hydroponics.

      The Fox Farms nutes we listed above are a good beginner’s choice for soil grows. Here’s the feeding schedule on their website: (PDF). Hopefully that should get you started.

      Alternatively, if you want to keep things really simple, just get some soil formulated for cannabis (Fox Farm Ocean Forest is a popular choice or their HappyFrog soil). There are a few options available. But avoid things like Miracle-Gro soil that have extended release nutrients – you can end up with the wrong nutrients still being in the soil during flowering.

      Good luck and all the best with your grow!

    While all this is of interest, I still find it difficult to make a selection because it appears these products are to be used in those Hydroponic Growing systems, not Soil. I’m a newbie & my first time I bought a Kit for Veg. (A-B) & Flower (A-B). When I got it, I found the directions for how to add it to a hydroponic system. I used it in my soil, scaled back in strength but, I spent that whole Time & expense only to end up with garbage. Why can’t these companies make it clear if the product is for Soil or Hydro ?

    • Mary Jane Farmer February 3, 2018 at 7:09 pm

      Not sure what product you bought that did not work for you. If it was a light, consider that the grow medium (dirt or water) really has no relation to how the plant responds to various light frequencies. If you are a hydro grower, that is a very technical and equipment intensive endeavor, but the light should not make a difference. If you have read our free e-book (find it on the right sidebar), then you might want to buy a more comprehensive Grower’s Bible. You can find that here.
      Good luck

    Im running Canna for my first grow ever solo grow, but have been working with a friend for years who runs Botanicare. I am extremely impressed with the Canna product line and while expensive, a video from BLG (Big Little Growers) on you tube gave me a feeding schedule that was dialed back slightly and still is producing an impressive crop. My friend used Botanicare and had inspiring results.

    Garden or farm can be made rich by using bloom booster fertilizer which is natural. As per nature if you follow natural things it will result long to you fertile soil. Chemicals destroy earthworms which are very much important for the soil.

    Canna nutrients is what I am currently using.

    I have ran IONIC , H &G , TechnaFlora B.C Boost line

    I have had great results with all.

    They just grow differently with each line.

    Advanced Nutrients line is very good for growing cannabis. Some say over hyped others say good marketing. They are pricey but worth it. You will not be disappointed.

    AN products are good and you say they are expensive bullshit. I use only a 1/4 of what they say and my plants always look awesome. I use a and b conni in flower and use only a few of their supplements. There is no need to use all of them. I use big bud, bud factor x, rhino skin, and overdrive only last 3 weeks, i dont work for AN i dont know ayone there and I have friends that have used many other products as I have too and maybe they are not as good of growers I don’t know I do know in the area I live in I am told my buds are by far the best and I live in cali so that is saying something

    What happened to the expensive Canna? They didn’t make this list. I have been using GH for the three years I have been growing. Gh seems good enough but if some thing yields better then the price increase is a drop in the bucket. I am ready to try something else but still want it to be simple. Advanced Nutrients has a expert set and a grandmaster set so all of the sudden the 3 bottles shown here don’t sound complete at all.

    Excellent goods from you, man. I have understand your stuff previous to and you are just extremely great. I really like what you have acquired here, certainly like what you’re stating and the way in which you say it. You make it entertaining and you still take care of to keep it sensible. I can not wait to read far more from you. This is actually a great website.

    Advanced Nutrients is pure hype and can be very confusing to boot.Far to many redundent additives in that lineup. GH products are very effective and less expensive.A very consistent and totally pleasing crop can be produced easily each and every time with GH. I have also found the DynaBloom to be a excellent stand alone in flowering.TIP- always use a potassium sulfate additive during late flowering because it is depleted very rapidly from the solution at this stage of ripening. Don’t be fooled into thinking your plants need PK, they don’t ; they need just the potassium. Take this advice your plants will have great aromas and wonderful tastes.

    • Topsrite July 25, 2017 at 9:45 pm

      You are absolutely correct about advance nutrients and also 100% correct about GH.

    • Purboar January 28, 2018 at 1:45 pm

      I absolutely agree with your statement about advanced nutrients and Fox Farms too bad the scientists aren’t actual medical cannabis patients at Fox Farms they have wasted a ton of my money and time the only product they have to me that’s worth anything is Big Bloom and with Advanced Nutrients the only thing they have that’s worth anything is carbo-load everything else is too much in your plant over doing it over nuding it and you’re going to burn Cole from all those inorganic salts just use fish Emulsion kelp Big Bloom great white humic acid fulvic acid and carbo-load less is more keep all those chemicals out of your stuff the world will be a better place

    • Zombie February 4, 2018 at 6:01 am

      Lol its a safe bet you guys haven’t really used there line up or you wouldn’t be blasting them. They are top shelf. And ment for cannabis. Advanced and Canna are what all the top growers are running so why do you knock it? Is it because your a parrot and repeat what you’ve heard from other low level uneducated growers??? I just don’t get it in fact you only continue the bad reputation of the dump stoner stereotype.

    • Zombie February 4, 2018 at 6:04 am

      You can’t use any of that in hydro and hydro is where the big boys play.

    • dave May 11, 2018 at 1:31 pm

      Thanks zombie,dirt farmers are so in the dark can’t imagine getting nutrient block and having to walk plant after plant to a warm water source. I just turn a valve.
