Growing Peppers in Hydroponics Jars - From Seeds to Full Plants (Part 2)

Watch our hydroponic pepper plants grow from seedlings all the way to fully flowering plants. This project spans about 3 months, from sowing seeds to the full plants shown at the end.

NOTE: I forgot to mention that I re-potted the plants early on in hydroton pellets. The rockwool cubes were developing some algae and the water had become murky. I changed the nutrients and carefully transplanted the plants into clay hydroton pellets in new net pots.

In the next video, I will be cross breeding these two plants to create a new pepper variety. Subscribe so you won't miss it!

you don’t receive enough credit for what you do. helped me out so much with all peppers. thank you sm

[melissabattiato]

This has given me the confidence to try peppers in my small hydroponic system- I’ve had lots of success with lettuce and kitchen herbs... might need to try this. Can’t wait for part three!

[cowsagainstcapitalism]

Thank you so much for putting all the time, money, effort and love into this. I have very limited space, light and materials (I want to grow max 🌶️ s of course) and this has helped me figure out what I need vs. don't need.

[GuitarsAndSynths]

awesome! I need to try this as outdoor growing failed for me and this looks do-able!

[chasef]

Both look great btw! Thanks for sharing the diy vid! Growing my first peppers in soil and they’re taking forever so I might use this method haha

At 9:13 you display a message that states, "I repeat this process as the plants grow and drink water, topping off the jars." In my experience, you should not top off the jars after the initial fill because the plant has roots that naturally do not sit in water but intake oxygen. If you submerge those, the plant will die or show signs of dying. This could be the cause of the Edema.

Rock wool is also excellent as a fire block!

The 3" net cups fit perfectly in the wide mouth mason jars.

Catching up on your work @PepperGeek -- great info presented tersely and professionally. looking forward to your work.

[mrelovelove]

Very cool video just found you love what you do. Keep up the great work

[caveman]

couple of things that causes trouble with pH. The sediment that later broken down will drop your pH. Air stones overtime in water will gradually raise pH especially after a fresh new solution/water replacement.

[Mikey]

You need to add ph adjusters to some pure water first then mix that in little by little to adjust ph. A good ec meter is a must.

Great video, very informative. How are the plants doing? Looking forward for part 3

Hydroponics is fairly forgiving of pH as long as minerals stay dissolved. pH is important in soil mainly because it effects the solubility of minerals. (and for extreme acid lovers like highbush blueberries it limits the nitrification of ammonium.) Anyway, most hydro mixes are nitrate based and esp with a single part blend they will be acidic in order to improve solubility. When the plant only has nitrate availible it will force the solution to higher pH as the nitrate is used, when ammonium is the main N source the plant will force pH down. This happens because the ionic charge balance must be maintained both in the plant and around the roots, so the roots release a -OH as an exchange for a -NO3, and they release a +H in exchange for a +NH4.
Use weak acids and weak bases to buffer pH, strong acids and bases are very all or nothing.(Weak and strong has nothing to do with dilution.)

The "ideal" ratio of NO3 to NH4 is not 1:1 because there are other ions involved like +K +2Mg +2Ca +2Fe and -3PO4 -2SO4, the best balance for many plants tends to be like 80%-90% of N from NO3. This is all specific to hydroponics, in soil there are microbes that convert NH4 to NO3 and clay particles with a net negative charge to hold the +NH4.

Did you put out a follow-up video of the cross pollinating of these 2 plants?

I got invested in the video and wanted to see the results of the cross, but I didn't see the follow-ups on your channel.

[brianforrest]

What did you do during the 13 days while you waited for the seeds to sprout?? Can you please do a day by day account of watering and lighting height if you are using grow lights. Thanks!

Brian

I have been growing red jalapenos and after 7 months they finally began fruiting. Between 2 plants they are producing 12 peppers and lots of blossoms. After another month the peppers are looking nice but still aren't red. The other night I was making pico and I harvested the largest pepper, about 4" long. As I was cutting it I took a taste. NO HEAT AT ALL. After 8 months?
What do you think is the cause?

[rubixmantheshapeshifter]

i had a shar pei dog long time ago, looks like my dog, well it passed away long time ago. im looking forward to seeing how this experiment goes.

[simplythewest]

Is it just me that feels incredibly guilty about removing healthy, surplus seedlings. I can't seem to bring myself to throw any away so always "try" and transplant them 😂. Awesome video btw

[RFabs]

Great DIY project - very inspiring. But isn't hydroponic more expensive that soil when nutrients have to be given constantly?
