Hydroponic Growing in Roll-Out Plastic Tanks II. Ginger

Edible ginger was grown in propagation flats and slings containing growing medium which were placed in roll-out plastic tanks at The University of Hawaii - Waiakea Agricultural Experiment Station near Hilo, Hawaii. The ginger rhizomes were produced to be used as clean seed pieces for the upcoming ginger crop.

Unlike other TH-cam channels, your videos have me consistently re-watching each video to gather details. This is great information, and demonstrates a clever use of materials. I have seen on sandy islands where pits were dug in sand, which were lined with plastic to hold water. I enjoy the creativity found throughout the world. Thanks for sharing another video!

Hi Matt - I also find myself re-watching some videos, because it is easier than trying to find the original data! I am hopeful that creative viewers will improve on this roll-out tank concept, so that it will become a good alternative for mid to larger scale hydroponic growers.

Congrats on your retirement. I’ve been there a few years and it’s great! Thanks for all of your hard work and these videos, which are wonderful!

[@growkratky5558]

Thank you!

Hello Mr. Kratky, wonderful video as always. I would be interested to know if you've ever measured the amount and type of plastic leachates present in the plants after harvesting. There are a couple of new studies measuring this in soil grown plants, and I think it would be interesting to compare with hydroponic grown plants, given the close contact with the materials and environment (degradation due to UV exposure, high temperature etc.).

[@growkratky5558]

No, I didn't have the capability to measure plastics uptake by plants, but that is a great idea. We are probably going to continue to use plastics in agriculture, and this type of information could help guide manufacturers to develop the safest plastics.

Thanks a lot for the information shared
. It's really useful.. can you please help with nutrient details for dilution in water like for preparing Part A and Part B solution

[@slaplapdog]

Begging your pardon but the roll out tanks always seem to have lumber or cement blocks along the sides, even though they are clipped to the inside flats.
I think accepting solid sides as necessary is probably for the best

[@growkratky5558]

You are correct, but I would like to at least aspire to a method without solid sides and that would probably require some sort of internal support.

Sir can you share with me what fertilizer went into this. Specifically the NPK and other nutrients and how the solution was made. I'm Basit in Ghana

[@supremus1305]

Thank you for all your work. It's really inspiring.
Couldn't the tank be held up by putting the tubes into the slings and attaching some L-shaped pipes as a scaffold?

[@growkratky5558]

Thank you for the suggestion!

Which hydroponic fertilizer do you recommend for leafy greens such as lettuce? Most people online recommend MasterBlend and was wondering if you agree

[@opusgamma]

Can we use sand as a grow medium?
