Aloha Jensen,
I’ve been calling various businesses (just to name a few: Mari’s Garden, Aquaponic Place, Ohana Greenhouse) on the island in search for 2 vertical hydroponic systems for classroom and have had no luck on finding any. Would you happen to know of vendors on the island that is selling it?

Jensen,
In your line of expertise, when dealing with vertical hydroponic systems such as the attached image, have you seen people use lighting such as the image attached? Two clients of my students (elementary teachers) requested vertical towers because of the lack of space in the room and needing to have enough grow nets for their students plants. The issue that I am foreseeing is the lighting for the plants which my students will problem solve to provide the best product for their clients.
Looking at the LED strip lights for hydroponics, would think this would work if my students create some type of support to hang these LED lights? What are your thoughts and/or solutions to this?
I also plan to reach out to both Ken Kozuma (Waipahu Inter) and Jason Akamine (Washington Middle) too.
Thanks!

Jensen,
I really could use your expertise in breaking down terminology for my students. With the start of Quarter 2, I am planning on having the students document the process of their seedling from germination to harvest (this is what Washington Middle did in the previous years).
<br>
I included the breakdown of the terminology but wanted to make sure if the definitions of these terms are correct. If it isn’t, would you help provide a simple definition that my middle school students would be able to understand?
<br>
Thanks!

This is what I am planning on using for the leafy greens for the classroom.

Aloha Jensen,
My students inquired about planting tomatoes and peppers and wanted to know:
– what type of fertilizer to use?
– where can we get this fertilizer from?
<br>
Currently, we just have the GH MaxiGro 2.2 lb (12/Cs) that was picked up from Ohana Greenhouse. If you could provide some guidance on where we can pick up the fertilizer to use in hydroponics, that would be greatly appreciated!
<br>
Thanks,<br>Randy

Looks like Washington Middle is in great hands! Definitely looking to see the progression that you all make throughout this school year. Hoping that one day Ilima Intermediate School can expand and go vertical too!

Aloha Damion,
Would 8th graders be able to use this program to design their portable hydroponic systems for clients? If so, I would be interested in learning more for Ilima Intermediate School and my students.
<br>
Thanks,<br>Randy

Aloha Jensen,
As my students and I await the germination of the butter crunch lettuce, I had two other questions that I hope you could answer.
<br>
1) One of the suggestions was to use distilled water and a couple drops of lemon to help the seeds to germinate. Are there other “secrets” to helping the seeds germinate quicker using rockwool? #secretstohydroponics
<br>
2) If I wanted my students to measure the biomass of the plant, what suggestions do you have that my students (8th graders) could do to get the biomass of the plant? How could students measure the biomass before and after? Could you provide some steps that would be simple enough if I had my students do this. #stilllearningabouthydroponics

Jensen,
That’s a great idea! Having the students research the light intensity and the color of bulbs (red, white, blue) will help put the ownership back on the students as they discover which type of lighting provides the best optimum growth for the type of plant. Always appreciate your expertise!

Jensen,
1) For Maxibloom, is this the correct package that you mentioned about flowering plants?
2) When changing the solution from MaxiGro to Maxibloom, do you suggest that my students empty out the entire bin that holds the fertilizer water and replace it with Maxibloom? OR do you suggest we have another bin ready and just move the foam board with the plants to that bin?
Always appreciate your expertise in this matter!

Okay thanks for the feedback Jensen!
-
Mahalo for your expertise on the definitions!

Ken,
<br>
Thanks for the advice and I’ll do my homework and look into it more. It’s been a while since I learned and taught about plants (ex: dictot). ????

Thanks for the feedback on the biomass question. If I wanted to have the students collect data on the germination and the development process of each plant, what would you recommend the students collecting? The purpose is to have the students collect data on the process of growing plants but I want it to be meaningful for them and for me. Is there anything important besides height of plants, # of leaves, that my students could collect data on ?
-
Thank you for the suggestion! I realized another reason why the seeds have yet to germinate is because the rockwool was dry. It was not until a student checked it that we realized we needed to moisturize the rockwool.
<br>
I definitely will try the suggestion!
