VIDEO: Germinating Seeds on Cotton Balls: an alternative to rockwool for hydroponic growing (Kratky too)

Happy to be the first here. I have to say, I love your videos because you have a really scientific approach and get to the point quickly. Thanks
I love this testing and comparing.
That was clear.
Great info thank you! Much cheaper than the rockwool lol
Great experiment!
Thank you for this info! Would I plant the seedling in the plastic net pots with the cotton ball for hydroponics or should I remove it from cotton ball first?
Exciting!! I was looking for an alternative to loofah. Some seeds are too small for loofah. Thank you for your inquisitive and experimental endeavors into hydroponics. I greatly benefit from your work.
Dear Tikky, thank you very much for providing the scientific results of this experiment. It's now good to know that we are free to choose whichever we want.
Look forward to the final results
Dang! this got to the point fast!
Thanks. I'll try it.
What medium did you use for the cotton ball seedlings?
I've never ever had success with cotton balls.
You're right. This is interesting. I wonder if half a cotton ball or a quarter of a cotton ball per seed would work as well as a whole one.
Thank you for great video! I'm looking forward to an update since I have lots of cotton balls! I also have lots of wet floral foam and I was wondering if you could use them as seed starter and also in this kratky system?
Wow! I think we did something like this back when I was in grade school, but I had forgotten about it. I can't believe how much money I've wasted buying rockwool cubes. Thank you Tikki O.
Interesting I must try this.
I'm headed to wally world to get cotton balls, good bye rockwool LOL
I thought of the cotton ball just like rockwool really right?almost cottons cheap right
Nice experiment!
Love your shows. Thanks I have a question it’s not related to radishes I don’t know if I can actually show you the pictures but I have lettuce growing in a hydroponic system but they don’t seem to be doing as well as yours in a mason jar. Is there a way to send you a picture you can tell me if it’s too small? Again I love you shows I wish I could figure out how to watch your shows from number one on on YouTube
It has been 2 months, how did the cotton ball work out?
You should have added your paper towel method as another comparison. 😛 One reason hydro growers don't like cotton is because it can come apart and plug up the pumps, which isn't a problem with kratky, the other is it isn't completely void of nutrients and can provide food for other organisms which probably isn't an issue with lettuce.
Thanks for the cotton ball tip Tikki. How did the lettuce do that started in the cotton balls?
You are AMAZING!!! Thank you so much for always doing these experiments ♥️
I always wondered about this method but never tried it due to cotton being organic and that could be a breeding ground for molds or bacteria! Thanks for sharing this! I will try it and see how my results come out! One could even add a squirt of peroxide to the soaking water for them to absorb and help keep things from becoming stagnant!
