  1. You don’t really dump that s*** down the drain do you where is it go to the next nearest river.. can I make a suggestion. have a garden hose come through the window and just pump it in your yard WTF upgrade your pump you can always turn the speed down so let’s start with the speed high

  2. At what level of conductivity/ppm ou know you need to refresh the fertilization in the system? sorry if this a too dumb question.

  3. My ph keeps rising from 5.5 up to 7.5 over night… Is this normal?

    I did research and asusmed ot was my air stoned but took them out and stoll habe the same issues

    Also is it normal for my res to smell like feet after a day or 2?

    Im using floragrow 3 part ..

  4. This is both informative and very clearly presented. I have not found another video that presents the answers to nutrient reservoir top-ups and solution changes as completely. Thank you!

  5. Why have an open water reservoir? Evaporation and Humidity must be through the roof! Do yourself a solid and put a lid on it……

  6. Learned about water nutes from Mr.Grow who shouted you out…So here I am…empart your knowledge on me oh Ganja Guru. I hope to share some content with YouTube soon!

  7. first time grower have plant growing now for three weeks looks good, how much nutrients should I add and when, thanks for any help

  8. Copper and zinc are not toxic. They are essential for our health. You didn’t give a solid reason for changing your solution. In large deep water systems they don’t change it. They just adjust as needed.

  9. My pocket book thanks you, and so does my plants. I’ll flush and clean and start a new batch tomorrow evening and start topping off

  10. I got so many bubbles going in mine that if i leave my blue lab meters in the reservoir while the air pump is on, it throws off the reading. I have to have the water stagnant to make a reading.

  11. You should never use your spent nutrients on your lawn, the chemicals stand a chance of mixing with ground water…not cool

  12. Damn you Everest, I was going to top off my reservoir but now I need to go do a reservoir change…
    Bye, gotta go..

  13. Mount your air pump above water level in containers
    If power is cut to pump. Water will siphon into the pump, destroying
    It.and clogging air stone.

  14. Hello. I have wanted to switch from coco to hydro for awhile. limited 4×4 spot not a lot of room. I have 3 rows of 3 plants for a total of nine only entrance from i side, The door.
    I also use trellis netting. So if i have 9 plants in trellis netting, how would i get them out of their container, or bucket to clean the container or bucket. If i had drains on the buckets or container would draining it , flushing it be enough without disturbing and scrubbing if i used a product like drip clean? Your videos are so real and no BS. Awesome.

  15. Uhhhh shouldn’t you not mix nutrients in their concentrated form…I’m sure you’re supposed to dilute them before adding to your reservoir. Adding nutrients in a concentrated form can lock out certain nutrients.

  16. hi , do you use same nutrients actually? but they change the name for aquatic earth / terra aquática and if you use it if you are happy with results ( taste, production,flavor , etc.) , thank’s.

  17. After hearing a bunch of stoned youtubers talking about a lot of useless gibberish, FINALLY found one that got straight to the damn point. Thank you.

  18. Awesome videos. I have a float setup that is connected to my reservoir. the water going in is ph’d, so the nutrient solution in the reservoir never becomes more concentrated(because of evaporation) and the ph remains in check so they are always getting everything 
    they need.

  19. Did you leave your res open? Have you ever encounter frothy and cloudy res water? My hydroponic solution always turn cloudy and frothy eventhough I already flush bleach into the system.

  20. 1key thing he forgot is salt build up…u have to run jus plain water for a day to flush out salts then empty it out then refill add nutes top off next 15 days then repeat

  21. Thanks for the tips! I have recently started growing some plants using the kratky technique and some of my plants suddenly withered and died yesterday. While troubleshooting the issue, it got me wondering how often I should change the content of the reservoir and your video has explained all that comprehensively. Thank you again!

  22. Everest I got a question maybe you could help me with. It’s my first time ever using hydroponics set up. So question is supposedly you grew strawberries do I ever need to replace them with newer plants once’s I’ve owned them for a number of years?

  23. I put a float valve in my reservoir and keep a separate water tank above it (gravity fed), so the water level in the res always stays the same. With that variable eliminated, keeping track of ppm is super easy.

  24. Thanks for the guidance Everest!! I have two questions now:
    If you were to add beneficial bacteria to the water reservoir, would that prevent nasty bacteria from growing as the beneficial bacteria would out-compete them? Also, to minimize water loss from the light, if you were to put a plastic tarp under the light, can you let water condense on it and then reuse the water?
    Thanks again for the help mate 🙂

  25. In DWC grow do you account for gallons in each bucket plus reservoir? Example: 4 buckets 5 gal. each plus reservoir= 25 gal. After refilling reservoir up to 25 gal. then replace?
