Coco flush in flower bigger buds?

  1. Heys guys or gals,


    I was on the site of greenhouse seed and they
    publish growing video's for each strain they sell, and I watched the grow video
    of them of Jack Herer.
    <o:p style="color: rgb(40, 40, 40); font-family: 'Proxima Nova', Helvetica, arial, sans-serif; font-size: 15px; line-height: 24px;"></o:p>And they say to feed them at an EC of 1.8 with a PH of 5.5
    but 5.5???? Isn't that to acidic
    <o:p style="color: rgb(40, 40, 40); font-family: 'Proxima Nova', Helvetica, arial, sans-serif; font-size: 15px; line-height: 24px;"></o:p>They also say to flush your plants around week 4 and 5 with
    an EC of 1.2 and let it dry out for 5 days so the roots can get as much oxygen
    as possible, and then blast them with an EC of 1.8 to get the maximum amount of
    bud development.

    But drying it out for 5 days?? Especially in coco because they
    said ‘'in hydroponic soil'' so Coco but wouldn't drying coco out for 5 days
    destroy the roots?
    <o:p style="color: rgb(40, 40, 40); font-family: 'Proxima Nova', Helvetica, arial, sans-serif; font-size: 15px; line-height: 24px;"></o:p>Any insight on this?
    <br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">''In hydroponic mediums (from rock-wool to pebbles to coco fiber) the flushing process is easier to implement, because there is a higher degree of drainage. The texture of hydroponic medium favors flushing, and it is also more necessary than in earth.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">When flushing hydroponic medium, it is very important to be exact with the values of the flushing solution. EC, temperature and quantity are very important factors. The EC of the flushing solution must be high enough for the salts to bind with the solution, but not as high as to form more salts. The ideal values are between 0.9 and 1.1.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;"><br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">The temperature must be in the 20-24 degrees Celsius range, to allow salt crystals to dissolve and unbind from the medium. If the temperature of the flushing solution is lower than 20 degrees the salt crystals will not dissolve, and if it is higher than 24 degrees the tiny root-hairs will be damaged.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;"><br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">And finally, the quantity of solution going through the medium should be at least double in volume (for example: 40 liters of flushing solution for a 20 liters container). In my personal experience, flushing with up to 3 times the volume is even more effective, as long as the drainage is quick.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">Flushing is best done at the beginning of the light-cycle, so to favor evaporation of excess water and to let the medium begin the drying process faster after flushing.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;"><br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">Once plants are flushed, they tend to get lazy, and slow down growth for a day or two, but this is all part of the game. As soon as the medium dries again, the growth (or ripening) resumes fast, and even increases.<br style="font-size: 13px; line-height: 19.5px; font-family: calibri, Arial, Helvetica, sans-serif; color: rgb(255, 255, 255); font-stretch: normal;">To double check the effectiveness of flushing, it is easy to measure the values inside the medium before and after flushing. First, pour some flushing solution through the medium. Measure the values inside the first liquid draining from the bottom, then apply the complete volume of flushing solution. At the end of drainage, measure again. At this point, the pH and EC readings of the flushing solution should be similar to what is draining out of the container.''
    \nIs it true that flushing in flower cycle let's say around week 5 will increase yield???
     
  2. I have been using this method for a while now. I like them to dry out for a day or so after every watering throughout the grow. I flush the medium just before the switch to flower . Then around week 5 or 6 depending on strain. I flush the medium with ph-6 ..EC 1.1-1.2 at a temp of around 18-20 c .then after a few days when the coco has just dried out. I give it a water with nutes EC- 1.8-20. Including the 10-15 ml of Canna pk-13/14.They explode with new bud growth after a few days , buds swell and sometimes foxtail a little. I have been using the Canna Boost for the last grows which defiantly improved the taste and buds seemed a little harder.

  3. SO it does improve bud development after the flush interesting.
    i'm almost at week 5 flowering I might try it see how the plants react.
    Dry it out for 2 - 3 days.
    Didn't need the flush actually besides the fact that it might improve bud development.
    Because I always feed with 30-40 % runoff every day.


     
  4. Don't dry out to the point of stress. It's amazing how long they go when you think there is no water left in pot. I read someone else saying not to let the medium dry out at all, my plants seem to grow better and stronger when it it let to dry out a bit.As they say the oxygen around the roots does help it grow faster. I find if the medium is constantly damp the plants will grow , but will be a little sluggish.

  5. topic is a few weeks old, but do you know what point it becomes stress when it dries out? i looked at mine this morning (24 hours ago) and they were drooping like a mother. they were underwatered, but didnt look like shit. just droopy. i watered them almost right away, but this is the first time i've underwatered them. just dont wanna stress more than needed.

     
  6. Usually tell by the weight of the pot. I will let them just start to droop a little not to much. To much stress may lead to hermi in some strains.
