Coco!

Discussion in 'Coco Coir' started by gmd, May 25, 2010.

  1. Been growing for a while but this is my first coco grow just wondering what nutes feeding/water schedule everyone uses. Using molasses as well.
     
  2. I have a plant in coco in 12/12 for the first time. I'm using Fox Farm Big Bloom and Tiger Bloom. I used Grow Big when I vegged her. I also use Botanicare Cal-Mag Plus with every feeding. Coco has calcium issues. For future grows, I plan to mix some dolomite lime into the coco.

    I adjust the pH of my water or nutrient solution to 5.9 - 6.0.
     
  3. I second the parts about first time coco, using FF steamed bone meal, cal-mag, and ph level!!! some websites, like maybe botanicare I don't know, have nutrient feeding schedules that you can follow if you please. make sure that you follow the instructions that are specifically for to the nurient you'[re using-- read the container label.

    otherwise just monior how your plants look and be VERY responsive when problems show up so they don't develop, enjoy!
     
  4. how much cal mag do u use? like tsp per gal?
     
  5. Exactly that much, though I anticipate upping that in the near future.
     
  6. it's best to use coco specific nutes, but not absolutely necessary. (i highly recommend house and garden) if you give a tsp. per gallon of plain ph'd water weekly, you should have no issues. i've used this method with pure blend and it worked fine. important to remember to get the 10-15% run-off with each feed. here's some coco info. from g.low.

    COCO COIR
    is a product derived from the husks of the coconut.
    Visually it looks like peat.
    It's air capacity is about 30%.
    Coir is most suited as a run to waste medium.
    Coir can become saturated and it is not truly inert medium.
    This means that the nutrient will change over a short period (due to the nutrient collecting micro and macro elements as it passes through the coir.
    Coir tends to release potassium and to withold calcium.
    For this reason it is desirable to use a nutrient that is blended specifically for coir.
    Coir has a remarkable capacity to protect the plants root system in times of heat.
    It also tends to promote vigorous and healthy root development.
    Plant growth tends to be very consistant with coir.
    Coir is very tolerant of over and under watering, which makes it a very forgiving growing medium.
    Coir has a very strong cation exchange ability, which means it can hold and release nutrient elements based on the plants needs.
    Coir tends to retain nutrient salts. because of this, less nutrient (lower ec) is required.
    On a less positive note, coir can also contain high levels of sodium (salt)....
    If your growing in coir be aware that this can be a potential problem.
    Either purchase a pre-flushed coir product or flush ph (5.5-6.0) stabilised water through the coir prior to use.
    Measure the ec of the water and then measure the ec of the run off.
    When they are the same, it is ready for use.
    Large amounts of potassium are naturally present in coir.
    Potassium competes with calcium and magnesium... buffering and plant nutrition needs to compensate for this!!
    For this reason there are several nutrients that are specifically formulated with the coco coir's unique characteristics in mind.
    By using a nutrient specifically formulated for the coir based system, you are ensuring that your plants are receiving the best possible nutritient package.
     
  7. Thanks lots of good information. Im using humbolt nutrients with Mag/cal. For veg I like to use Flora Nova. They didn't have any specific nutrients for coco or else I woulda used them.
     
  8. Any hydro nutes are fine, like mentioned above you just have supplement some calcium, especially in flower and ph everything going in to 5.8(ish). Good luck man, you'll love coco!
