I am so glad I found this video I didnt know why my plants were dying when I refilled with the nutrients Thanks so much for video.
Do I just add water or more nutrients, no one ever talks about it
What a good Video! Well done keep em coming!!! :)
A great way to begin a new growing cycle is to enjoy one of your refresher videos on plant maintaining Khang! Happy New Year to you and your family. Are you making much progress on your latest property? -Bob...
Wow! Those are some nice looking roots you've got there! 🤍
I think that's why my kratkys don't do better. I let it run all the way down before refilling.
So how often should you change the nutrients?
Do you ever just top off with water?
How do you stabilize tall or large plants in a kratky setup?
Really useful exact answer to my Google question. Thank you!
Might try some kratky this year
Not sure where to ask this since I haven't seen you doing your livestreams lately. Wondering if you ever considered making a video on growing hydroponic strawberries? People seem to prefer an NFT system for it vs kratky. Hopefully you enjoy the berry yourself and wouldn't mind showing an easy way you might grow some strawberry plants for a steady harvest. Thanks..
How frequently do you recommend changing the water? I think I’m waiting too long and my roots are getting brown and slimy. I do have an aeration pump in my 5 gal containers.
If you have an aeration pump, that is "Deep Water Culture" and not Kratky. I've read a bunch of people online using H2O2 to clean off any of the gunk that has grown on the roots but haven't tried it myself.
Online, I've heard 2-4 weeks. And adding a small amount of hydrogen peroxide. There is also a "kratky vs dwc" video on youtube by somebody else that shows an aeration pump making algae more of a problem which can feed root rot bacteria
@@stevenp5296 For what it's worth, I've had a few mason jar kratky set ups that started getting root rot and hydrogen peroxide did absolutely nothing to help once it's set in, and if you use too much it kills the roots. I've added it to my nutrients after I've mixed them together just to make sure the solution is disinfected for storage and that seems to have helped keep the rot at bay when I actually use it. What did work to fix the plant was cutting the roots past the rot, rinsing them off really well, disinfecting your jar or bucket or whatever, and then putting it back in with fresh solution up to where the roots are. It takes the plants a little bit of time to bounce back though, but it'll be way faster than using peroxide on brown roots. He has a good video about doing that on this channel too.
Great video. Thanks
Good tips. You also want to change the nutrients when the EC gets to low. When the plant sense lack of nutrients the PH will start to rise. Thats a sign. I change when EC drops below 0.8
What is EC?
@@idahogardengirl942 EC stands for Electric Conductivity. Simply put, the EC value is the salt concentration in your substrate or nutrient solution. The salt concentration is a good indication of the available nutrients. This is why the EC value is important: it tells you if your plants are receiving the right amount of nutrients.
Thanks
Technically kratky is a circulating method (closed system) because the same nutrients are reused until they are replaced. With a non circulating system (open system) the roots only see the nutrient once and it isnt reused.
So for keeping long term plants as peppers (unlike set & forget for lettuce) the air root growth seems to make an easy system quite "complicated"? If I have to refill every other day kratky isnt suitable for vacations for example. Is there a natural build in mechanism for air root to water root ratio or are there counters for air root growth like using a tall container or keeping the roots wet by using fabric/stockings?
Я практический не понимаю что ты говоришь, но голос очень успокаивает
