Easy Hydroponic Lettuce Using the Kratky Method and Soda Bottles 

You have a nice deadpan sense of humor.

This is the best video I've found on the topic. You explained everything extremely clearly with no nonsense, from start to finish. I also like how you describe your mistakes, the reason behind them, and then the solution you found for them. Very well done. 👏👏👍👍

Just another great idea on a great and detailed video. Thanks Tikki for your patience and dedication.

You are flat out a friggin genius!!!! I LOVE your videos. Love from a new fan🥰

Almost every question I have regarding hydroponic experiments, you have a video for. Brava!

You make this look so easy. My hydroponic Journey was vey short. LOL! I'm going to try this. Thanks for sharing.

Pepsi vs coke joke. You’re awesome! You’ve taught me so much. Thank you!!!

Great video, I'm learning a lot from you. Thank you

I always enjoy your videos. That was great.

thank you., this is KIS (keep it simple). With so much good info .

lol I love your humor.

I always like your videos. Great info in each of them. Thank you for doing this

Thank you so much for sharing.

Wow, nice one!

Thank you for sharing. I started some beans like this in cotton balls. Didn't work. So next, I started seeds in vermiculite and perlite. So far so good.

So glad to see that you're still producing videos. Often with a video, I encounter dates going back years and I wonder what happened. Did the techniques shown not really work after all? At any rate, I'm glad you're still active in the YT community. I've done cucumbers via an ebb and flow, in a greenhouse with amazing success, but come Christmas, I'm going to set up a grow tent to raise vegetables using both Kratky and DWC. I'm excited about the prospect of producing winter vegetables. Thanks again for your continued contribution to YT. In many ways, you have become my mentor.

This video made me to subscribe your channel, great stuff , keep up the experimenting things...

Thanks for videos.i like it

Thanks For your video. I appreciate all your experiments & honest trial and error. It helps us all to learn what can happen either way! It makes me want to consider if I want to try other hydroponic methods to grow. Now I know through your experience that I will stick with the kratky net cups growing in jars. I enjoyed all your lettuce kratky methods and experiment videos the most though! 😊 I enjoy hearing the way you explain everything with your sweet sense of humour. Yours are the best!! 🥰

Great video, thank you.

Thanks tikki o your the best

nice. thanks for the inspiration as always.

I've been wanting to try hydroponics but I've found the "entry fee" to be out of my budget for a bit- but this looks perfect! I already have a brick of coconut coir and plenty of soda bottles and lettuce seeds! ♥️ Thanks!!

היי...אהבתי את הכיתוב: "כשר לפסח" על הפקק של הבקבוקים...

Love it.

hello there Tikki....I have been enjoying your vids about these different ways of using containers and different medium....I am now in a boat load of supplies an amazon is now a frequent visitor to my mailbox..lol...is there anyway for us to share photos of what we have done?..I think is would be so much fun and inspiring to see more progress of all our ideas and utilizing yours...thank you..from a loyal fan...

Great videos, love them, very educational! At what point did you switch from AeroGarden fertilizer to stronger fertilizer? Thx, CazM

Excellent. Thank you.

I love your videos Tikki - you inspired me to begin my own hydroponic journey following your detailed instructions :) I noticed my cucumber plant leaves curling up a bit and the edge and slightly yellow, the leaf is also slightly dry and almost papery to the touch instead of like a leaf .. the new growths are normal but I am afraid they would suffer the same fate if I don't figure out what the problem is and fix it. could it be my PPFD on my grow light is too high and I need to move the light higher up? right now it is at 22" away from the cucumbers in a DWC / masterblend nutrient / pump / indoors - I have photos if you want to see :)

Newbie with Kratky method, please show more details in the process like lights for indoor plants growing, water change frequency, nutrient solution (or if possible liquid nutrients DIY)

Keep working. Good luck. 👍

Great video!....I did the exact same experiment last winter..was fun!..only difference is I put hole in the cap and ran wicking rope through the hole and I use a 30 30 30 mix if coco coir perlite and vermiculite..basil lived it!..so did micro dwarf tomatoes 😀

As usual a great video, thank you. ¿Did you add more nutrient solution as the plant grew?

Thanks again and again🙏🙏

Great loads of lettuce!!! I like to sprout the seeds inside a small clear plastic container, sprinkle with water, close the lid and put on top of the fridge. Just sprinkle again if they get dry, until they sprout. Check after every couple of days. Outside is too hot for lettuce...

Great video. One thing though, the alge won't inherently hurt the roots, but what it can do I starve them for nutrient. It can burn through the nutrient in the solution and can also get so thick in the solution that it will choke out the plant.

Very good. Mam, pls let me know about water changing. Thanks

An idea: What if you kept the bottle cap (with some small holes) and you used one good sized cotton ball in the top instead of the coco coir? (a) cheaper, (b) keeps your water cleaner maybe.

Hi Thats great video I want to ask if you are adding water to the bottles from time to time or no Also for (geminating) period do you keep light on And using different type of light is it affecting the growth of the planet Thank you very much

Hi, can I add nutrients after the plants grow true leaves? Thank you!

before the seedlings roots grow down enough to reach the water do you have to water from above at all? Or does the coir bring it up through for them from the bottom enough? cheers!

Dose this method produces seeds to harvest if so can you do a video on it

if you start the germination on coton balls the only thing to do is drop the coton ball with the seedlings into the top ,instead of using coconut coir ,checking that the root is growing towards the water .

"1 out of 5 ain't bad don't be sad now don't be sad 1 out 5 ain't bad" lol ty for the video

Love your vids.. I do this with gallon jugs, medicine pill bottles as cups, perlite for medium, and foil to block light..real cheap set up..black seeded Simpson works best. 1 tsp Epsom and 1 tsp WM. brand miracle grow for solution.

in terms of old seeds i think it depends on a few factors: one being they should stay dry...remember Art Combs found those watermelon seeds in a cave not only where they old but could've been a thousand years old but he grew melons from those he found.

Can you reuse the coconut coir soil replacement

How often do you change water? How does oxygen get to plant? And how much water do you put in bottle

Tikkie did you pour your mix (liquid fertilizer) over the coca Coir or you just planted the seed in the coir bare ???

Hi, when do you add nutrients to the water? Do I let seeds germinate in water or nutrients please?

May I make a suggestion? If you use some cotton yarn or any cotton medium you can use it to wick the water up from the bottom water reservoir. It will go up the yarn and self-water for a long time and you do not have to water until the reservoir water runs out. You just have to run one or two long strings from the bottom of the bottle and up through the dirt.

How do you overcome the algae growth in clear containers?

You need to test the lettuce for caffeine !

I’m wondering if the electricity cost is more than you buy a head if lettuce from supermarket

Can I use soil instead of coir

Does lettuce only last 3 months before having to fully harvest and replant?

Looking for your feedback. I started 3 Romaine lettuce 🥬 plants from cuttings each about a week apart. They were all in Masterblend mix and doing great. Their growth seemed to stop at about 6”. One just turned yellow and is dying overnight. I keep the level of nutrients about 1/2” up the end of the stem. The stems or cutting cores are shriveling up. They are inside in a window. They aren’t Heat stressed. Any ideas? Thank you sooo much.

How was your YomTov

What were your ph levels ?

Hi Tikki, did you need to refill the soda bottles with water and nutrients at any point or did it last the whole experiment? Great video!

Hey, since your seeds were old, wouldn't it be cool to let a couple plants go to seed and collect fresh new seeds to grow next time? Thanks for the video!

But how the seeds growing without watering them

I did this with Poland springs bottles and dollar tree soil. No nutrients in the water. They have sprouted, but I don’t know what to do next 🤷🏻‍♀️

It looks like all the watering is from below. In other words, no misting from above at all, correct? Thank you for the lesson!

Will you do a medical cannabis Kratky grow please?

Hi . How far should I put grow light from my lettuce ?

I pulled a string thru the bottle cap and let it dangle to the bottom of the bottle to wick up the water when the water level is below the bottle cap. This way the plant will not wither if I forget to fill up the water to the bottle cap level.

Can someone please discuss the discarding of the solution properly???

An empty glue gun works well too if you don’t have a soldering iron

I'm told Coke is more lucrative 😂

Again and sag again💐🌹 thank you🌹🙏,
