Thank you Dr. Kratky!
Dr. Kratky. It's lovely to hear your voice. You're such a fun gardener. I had to go to 4:01 to see how the ends of the tank were closed off. Thank you for sharing yet another ingenious experiment.
Ha, this is a smart way for me to still produce some food while voles/moles tunnel through my garden. I have no plan to kill : )
My mfkin man the OG legend. You represent deep man. You my roots!!! Halaaaa!!!!
To be honest your growing success seems like black magic sorcery to me. 🧙♂️ I'm super excited to try out some of your methods over here in Germany. Thank you.
Maybe it is green magic!
The peppers can indeed. Makes sense to increase EC during the grow, I might try this. As always, very informative. Big thumbs up for you and your singing, kind sir. I hope all is well.
Thank you kindly Hydro Haven. I always enjoy hearing from you and happy to hear the compliment on my singing!
You are so funny! Thanks for another interesting video with fun things to try out.
Thank you! I'm happy to hear that you liked the video!
That would work awesome with 3 gallon rootmaker pots on my balcony. I'm going to try it with cherokee purple and coco coir
Thank you for sharing some great ideas!
That is an awesome system, especially the tomatoes! I like the drip tape used to secure the plastic, use what you got. Could you also build the frame a few feet shorter in width and just lay the plastic up both sides or does wrapping it like that help lessen the evaporation?
Thanks, Mike. Yes, you could do that depending on the intended crop to be grown. Actually, this concept is in its infancy and you are all pioneers who will develop this into something beyond what I have imagined!
Happy to see another video. Hopefully, you were able to spend time with family and friends when out there. Compared to your Hilo research, this looks more like William F. Gericke's beds in ways. Perhaps merging this study with Gericke's approach, the top grow media could continue the length of the bed. The flexible bed liner is an easier modern solution to building the old beds made by Gericke. So adapting modern materials to Gericke's research would offer a substantial improvement to current gardening methods?
Very astute observations and comments, Matt! The similarity to Gericke's beds hadn't occurred to me. Modern plastics were not yet invented in Gericke's time, and they would have allowed him to progress much farther than being constrained with such materials as concrete tanks.
Prof, is kratky sandponic possible?
Does the drip tape water each plant until it fills the plastic tank with 2" of solution? I the this like an auto pot method?
No, the emitter spacing was 12" apart and wasn't coordinated with the plant spacing. The purpose was to deliver nutrient solution evenly throughout the tank.
Love the idea of this method. Would like to see the tanks higher so one doesn't have bend over in order to tend.
While my undergraduate training was chemistry, I'm very confused about the terms EC and mS. Can you please direct me to where to find this basic instruction?
There is a discussion on this starting on p. 10 of www.ctahr.hawaii.edu/oc/freepubs/pdf/VC-1.pdf
@growkratky5558 thank you very much!!
Great idea - hopefully this could work out cheaper than some alternatives - e.g. gutters or specialist gear. Is this a draining / flow system, or did you seal the ends somehow? Thanks :)
PS - the 1,000 L IBC / Tote cube containers are great for storing solution etc
You can see in some photos ends of the plastic are bent upwards so this is no flow system, just maintaining constant level of solution.
@Freedom Family A 10 meter long polystyrene box would cost a lot more than this probably. In New Zealand it looks like I can get 10m of white polythene for around $15 USD. Might need something better/more expensive ideally, but looks promising.
@@dmitryplatonov I saw one image where the end looks bent-up a bit but not obvious thanks. The Word document describes it though, and yes it is intended as a no-flow system - though could easily be adapted to flow on a slope etc.
@@afmedwards Yes, you are correct! The ends were bent up to prevent the solution from flowing out and this becomes a passive tank with no flowing or draining of nutrient solution.
Thank you Dr. Kratky! I've been experimenting with your method, having pretty good results but the internet is scaring me into not wanting to eat the produce because there's a lot of talk out there about synthetic nutrients like MB being bad for one's health. I would sure appreciate all the replies I can get with things like, "We've been using Dr. Kratky's method for years with MasterBlend and are in great health, better than ever, don't be afraid to try it!" Thanks all in advance!
