      What's calculation for ppfd? Umols?
      1. churchhaze
        churchhaze
        average ppfd = ppf/A

        umol = 1/1000000 regular moles

      So do you use one part in your dwc haze !? From start to finish am thinking Fp for veg and ionic grow for flower it's 315 !? An used a bit off silica to ! how about you or you just a one bottle man !!?

      I've been wanting to learn how to make my own recipe, so thanks for breaking things down in the forums. I've been growing in Colorado for these people using Cal Nit, Mag S, and this product called Chem Gro for awhile. Seems to work, but not always consistent. I've been wanting to be more dialed in and make a stock A + B solution opposed to just making enough for each round.

      This is my first post and I joined because of your post and knowledge keep it coming. So interested in mixing my own raw elements. Extremely confusing if your starting from scratch.

        It's very easy to make stock solutions from scratch with the help of hydrobuddy.

        You can't go wrong getting a few pounds of calcium nitrate, potassium nitrate, and monopotassium phosphate and magnesium sulfate.

        Iron sulfate will work if you're mixing directly into a reservoir, otherwise you want iron dtpa 10-11%.

        Honestly, you could grow plants with just those ingredients, but you'll also want to get small (tiny) amounts of sodium borate, manganese sulfate, and sodium molybdate. These ingredients will all work for making a+b stock solutions.

      DWC...do you see a change in growth at all.

        I doubt you will see much difference in growth rate regardless of which hydro medium you use, as long as you are using an inert media with hydroponic nutrients.

        Growth is good with Mix #17 with an EC of 1.4.

      Hey churchaze, I posted in the heat sink thread has going on about needing something to passively cool my vero 18's. I have six of them and was going to divide them up into 3 each on a large 10" to 12" long sink from heat sinks usa but Supra said I should check out your build that used the 10" profile. I'm not familiar with this could you elaborate on where you got it and if they cut it for you.?

      Hey churchhaze, Can you point me in the directions of some good reading info about the science behind mixing nutrients. Especially articles that elaborate on calculating elemental ppm.
      1. churchhaze
        churchhaze
        Check out scienceinhydroponics.com

        It's the blog from the guy who made hydrobuddy. Also get hydrobuddy and learn to use that. It's an invaluable tool for designing your own mixes.

        Elemental ppm is just mg/L

        5mg in 1L of total solution is 5ppm.

        The periodic table is how you find the molar mass of each element, and thus the molar mass of entire molecules, and the percentage of each element by mass.

      You think the reason everyone on the forums complains about root rot is because you do hydro differently then most?

      Many people use organic nutrients, organic supplements (with or without them knowing it), and ph down that contains citric acid. Also a lot of people use micronutrients that are chelated (daniel suarez wrote a good article on feeding microbes).

        I use 2 airstones per 4 gallons of water approximately and pump a lot of air. I've never bothered with chillers or bennies, and to be honest haven't heard of anyone chilling their nutes until the last few years.

        Never seen a root rot complaintl...l. Month ofer water. Pretty simple. That's early on to learn. Get a mourner tester for 10 bux.

      Lots of people seem to be freaking-out that I'd damage/kill my plants if I water them with a nutrient-solution of a 4.0 pH, and only you and one other person say that soil will buffer the pH significantly, and that I have nothing to worry about. Watering with a highly acidic solution will be just fine, because the plants are in soil...

        A pH of 4 means nothing at a low concentration.

        If you take a gallon of water and put 1 drop of nitric acid in, the pH will plummet.

        The higher the concentration (ppm) of a solution, the more pH matters.

        If you put that same drop of nitric acid in a concentrated nutrient solution, the pH is barely going to budge.

        The buffering capacity of pure water is 0, so any amount of acid will cause pH to plummet.

      [QUOTE="churchhaze, post: 10771441, member: 171854"]Even though I don't really do soil anymore, I totally agree with this.[/QUOTE]
      Just out of curiosity. Since you switched away from soil and seem to have been growing for a while. What medium do you grow in now?

      Hey churchhaze. i appreciate u sharing the mono potassium phosphate. i was wondering if you might know where i can find ammonium phosphate in bulk and for a cheaper price than what i get for it from raw-soluables. i am looking for an npk of about 9-61-0. let me know if you know where i might b able to find this. thank you very much for your time!

        If this is for a hydroponic system, you probably won't need any mono ammonium phosphate as it's good to keep ammonium levels low in a hydroponic medium.

        The majority of nitrogen should be provided as nitrate salts (calcium nitrate and potassium nitrate)

        thx very much good sir. i have been using this.. http://www.raw-solubles.com/images/labels/RAW_Phosphorus_Back55.jpg it's pretty good, and i see improvements in my stems as they are now thicker and my plant seems to be sucking up more nutes. "add to any feeding schedule" at 1/8 tsp per gallon. ty for ur suggestion but i will keep looking!
