Regrowing Supermarket Lettuce Experiment: Soil vs. Water vs. Hydroponic Nutrients 

this video reminds me of youtube early days. videos to the point. no pandering. no bull. awesome.

“I drank the coffee first.” Love it!

Most seed starting mix is meant for germination and will contain a certain amount of inert material that inhibits mold growth. It doesn't usually contain nutrients which are usually added when they are transplanted to soil. Some people enrich the soil before transplanting. The hydroponics mix definitely had an advantage over both the soil and water because it was the only one that provided any nutrients.

Finally a person I trust made this experiment. Thank you, Tikki! 🌷❤️

This was very helpful saves me so much time experimenting the same thing, finally someone shows a comparison of the three! I was shocked the soil one didn't grow as much, interesting! Thank you!

"I drank the coffee first"... I love your personality! Thx for sharing

Thank you for doing these experiments for us and saving us time....your information is invaluable.

I am sold! I am planning to get my lettuce going in a nutrient solution then trans plant to a container with soil. Thank you for your video, nicely done.

You are funny. I am sure you are a beloved teacher of all students.

I love doing experiments, well done.👍

This was a GREAT experiment,gave me a very accurate idea of what the differences are,as I am new to the concept of hydroponics..👍👍

Yep, thank you for doing the experiment, just what I was hoping to see, thank you for your interest and helpful video.

Nice experiment and I also found some humor in here.

CUTE WITH THE CLASSICAL MUSIC ABOUT THE GROWTH!

I am new to hydroponic gardening. I truly appreciate your videos, showing the different grow methods and results for each - fascinating to see the actual results and the comparisons. Keep growing! Really like your content! Happily subscribed!

please make more videos, I really enjoy watching it very informative.

I am a new gardener, but I have noticed that all my plants in the garden grow better and faster after rain than when I water them with tap water every day. The secret are the minerals in the water :)

👏👏Thanks for another great video! Awesome experiment! I can’t wait to try this as well. Never again will I toss lettuce stumps.

Great science experiment!! I would love to try this at home with my children. Thanks for the effort and time.

Your channel is a HUGE blessing to all of us who want to prep for our families so ty!♥️♥️♥️🇺🇸

Thank you Tikki. I have done the same with water and solution but not so controlled so there was rotting. It never made it to my salad bowl in the past 6 months doing it. The same was done with celery, cabbage and onions. Thanks again, I have seen many of your videos. They are enjoyable and educational.

I loved your experiment. I’m surprised the plain water lettuce did just as well as the one with the plant food. All in all great review. Good job 👏👍

You're my new favourite. You're hilarious! 😂 You got a new subscriber here

Cool experiment

The question that comes to mind for me is are any of them holding more vitamins than another? Is the one planted in the dirt healthier to eat or is there no difference?

“I drank the coffee first”😭

Hahahahaha!!! I love this! I love you. You make me laugh. You are just natural! I am subscribing!!!

You must be a teacher as your profession! Best channel out there on this!

Would you make a cup of that coffee for me please? I'm coming over to play plants with you! 😀 Seriously, took a look at my romaine tonight. Planting it tomorrow. Thanks Tikki! 🎈

Thats awesome experiment. I am buying those grow cups and the growing medium you added to the water.

I look forward to seeing your videos. I always learn something new!

I really like this experiment, I was told by someone that you have to cover the romaine stump up completely leaving only the very top out of the soil. I have just planted my stump and I hoping for good growth like your delicious lettuce. Thank you.

I know this is a long shot, but if you ever see this, I think it would be interesting to test a compost tea water as the simplest and cheapest solution. Water should be chlorine and other chemical free. Nice video...wish I saw it sooner.

You are a godsend! I can’t wait to throw back some coffee so I can try this!

I’m enjoying your videos so much. Keep it up with these experiments!

I loved your methodology! You convinced me to keep at it. I loved the music and your light commentary. Some of these videos the people talk too much!!! Thank you.

Wow congrats on going viral! Your videos are always so thorough and smart. Thanks for sharing all your fun garden experiments.

Very cool ! I'm doing the similar experiments at home with bok choy, which will grow back just like lettuce. Also made a mini DIY aquaponics system growing hot peppers in a tray placed atop a little fish tank that has live shrimp in it. The shrimp are called Amano shrimp (Japonica) which are kind of bottomfeeders and will eat algae, but they do appreciate a tasty snack once in a while. A few kernels of cooked rice or vegetables, they will devour anything, even a piece of cooked shrimp (little cannibals they are). My DIY system has no fancy bell syphons or valves. I cannibalized a very small (8 euro) aquarium filter that pumps the water up, like a mini pump rather than a filter, with a timer on 30 mins on, 30 mins off intervals. That way the plant roots get a lot of oxygen. Gravity does the rest. After poking a bunch of holes in the tray the water rains back into the aquarium. It would seem foolproof, w/o chance of flooding because the water simply has nowhere else to go but down and drip back into the mini fish tank. Sofar (A few weeks into the experiment) the peppers are doing remarkably well. Much better than the ones growing in soil on my balcony outdoors ! I hope to pick some fruits off these peppers in a month or two. The light source is just cheapo LED light fixtures from budget places here in Holland that would be comparable to Home Deput in the US. It seems to work with a cool white/warm white combo. You could theoretically grow food or plants on any bookshelf, anywhere.

Your experiments with hydrophonics are really very educative

To me it just goes along with what I found out when taking Plant physiology. Plants need through the roots each of 18 basic element, like air to zinc. The potting soil had bacteria and fungus taking over the availability of these essential elements. Plants take in inorganic chemicals, not organic fertilizer. Water and plant base also had chemicals. Distilled water and seed is what we used!

I drank the coffee first! That made me laugh out loud!!

Great video and thanks for doing it a 2nd time to confirm your findings. However, I wished you had shown us after Day 6 if there were any roots growing! Also, between Day 12 and Day 21 it looks like it's already beginning to bolt as it is getting long/tall & skinny. Your grow light may be 6500K Daylight temperature, but it's awful high. It also matters the amount of lumen (something greater than 2000" lumen would be nice) it puts out and also the power in watts (20+ watts) that it produces. Try lowering the grow light and treat the scraps like seedlings.

Great experiment, thank you for doing this.

Thanks for making an updated video. I love it when you do this particular experiment.

ThiS was an awesome experiment to behold!!!😃I have a lil Chive KiD growinG on my Window sill that I am moving to a new container thiS week and I came to your channel to see if I should do a hydroponic experiment soon and the answer iS YeSss!!!👍ThankS for your very detailed explanationS to assist humanity through these turbulent times!!!✌😇🌎🌹🌞🌹🐰🌹☕☕☕

Does anyone know what happens in relation to the nutrients? Does the one that grows in the soil have more nutrients than the one in the pure water?

This makes sense. Without a root system to seek water and nutrients in the dirt, the pure liquid form of nutrients will penetrate into the plant fastest.

Great demonstration Tiki! Clearly the hydroponically regrown lettuce responded best. My question: have you done a “taste test” on all 3 yet? If so, I would be interested in knowing if you noted any difference in their taste or texture and if so, which was tastier.

Wow! And soil is so expensive relative to water!

Nice job making an interesting video.

This video came just in time. I just bought a 4 pack of little gem romaine lettuce. I'm definitely trying this!

Great video, thanks. Would be interesting to compare the growth of one in water and one in water under a grow light.

Tried this too! Thanks for your time!

Very enjoyable experiment and video! I like the way you think. Thank you for showing this experiment!

As Far as Nutrient Density! I Bet The One With Soil and Hydrpo Solution has the More Nutrients!!!! But Great Video!

Your channel is underrated.

Love experiments, good job repeating it with pairs

Thank you Tikko for your consistency! Super cool!!

Great info!! Working on my stumps today👍🏾

I guess this makes sense. lettuce is water and fiber with little nutrients that would require a rich food like soil. sunlight and water= lettuce. thank you.

Great experiment! Love how you added Beethoven's 5th as well! My only thought is how much water were you giving the soil plant? Thinking it would take daily watering for maximum results

Very interesting Tikki. As you already know, one can regrow a variety of supermarket vegetables. Eg. once a year i buy green shallots (green onions in the U.S.?) and plant the cut off bottoms in soil, harvesting them as needed.

Awesome video. Thinking about growing my own lettuce and u gave me an idea to grow then in water vs soil and remind myself to keep the stumps. Fun experiment 4 me to try! Thanks

I drank the coffee first 🤭 So cute!

Always a treat to watch your videos. Do you think you can do a video on growing Esrog from seeds. I would love to see you focus your talents on that! 😊

Seems to me like your window just gets better light on the right side that time of the year. In both experiments the right side did better. 😊

I'm going to buy lettuce tomorrow 🎉

I have just recently tried to grow lettuce from one I got from the store and well.. it did grow similar to the ones in the video and I just the other day placed it into the soil and I noticed a flower growing on it, and well... I have grown lettuce from seeds before, but I have never seen a flower bloom from it.

Thanks for doing the experiements, the soil finding was particularly interesting. Hopefully my lettuce will grow so well :)

Thanks! I wonder if using unfiltered water in the second one would give it more minerals and make a difference.

I dug this. Thank You

Im trying this for the first time im doing the water for 2 weeks and then transfering it into soil at least thats what i saw from another vid so i hope it works

It's around the 3rd week after planting where there's a soft ceiling for the lettuce in water vs the hydroponic solution.

Is it necessary to plant it in soil after some time in water or can I continue growing them in water?

Very interesting/ I am trying celery only 2 days but I see growth. I will use the Hydroponic water and see if it works on celery. I see your lettuce is Cos or Romaine... My favorite I have some in the ridge.. I also love experimenting... Thank you.

Different experiment ,very good ☺️ I love 😘

Excellent instructor👍❤️

I’m going to try this

Great video!

love your videos. You make growing stuff exciting

And my mother always said coffee stunts growth! Turns out DIRT stunts growth- nice experiment I hope your salad was DELICIOUS

I love your videos. You explain things well for me.

"I put the bowel higher but I don't think that is the reason" 🤣🤣👍 I will go with plain water because it seems there is no difference except by a day or so. Would I be correct in assuming that it would continue growing from the same root each time with this process? Thank you for this Love and light from South Africa 💚

Nice Thanks. This is exactly what I was looking for!

Thank you

Hello Tikki O.! I loved this vid on growing mediums. As your well aware of, marijuana smoke tastes much better when grown in soil instead of weed grown in a hydroponics system. Does the same apply with the lettuce? I would love to see a video on taste testing lettuce grown from each medium!

Great job but the only difference I saw with one the plant with regular water in the folders cup, it got outdoor sunlight more than the other two but it was still a good experiment.

I must try this experiment you are great 💓🌹

Thank you for this. I love the little wood thrushes that keep going to the feeder. They are adorable little song birds. I totally trying this. My turtle eats a lot of Lettuce, so if I can save a buck or 2 I am so down for it b

Thank you so much!

What a cool video thank you so much. Lov

That was awesome Thank you 🙏

Thank you. It's lovely. I'll try it.

That was cool thanks. 😎

Greetings from Norway. I really like your entire hydroponic/Kratky series and have already subscribed to your channel. What was the tasting experience comparing with your Kratky lettuce from seeds?

Fantastic! excited to do this!

Thanks for this experiment.

thank you..

Thank you for sharing!!!

I love your videos and experiments!
