Is bigger better? In this experiment I am growing Bok Choy (also known as Pak Choi, Bok Choi, or Pak Choy) in small cups two ways, on cotton balls and in rockwool. Please enjoy this small experiment…..I did!

Great experiment.
Thank you!
Thanks for the film. How often did you change the hydroponic nutrition solution?
That’s Nice I made the mistake of putting six lettuce seed per cotton ball and they all germinated some are even growing roots through the ball haven’t put it through the mason jars yet
coolio experiement. thanks for sharing.
Those look like they turned out to be tatsoi more than bok choy unless the stalks ended up fattening up.
You never mentioned light. Indirect? (I'm buying some seeds and a grow light for these if needed). Thank you!
I love watching your gardening experiments
Perhaps the roots don't have enough air. Perhaps if you double-cupped it, it would create more aeration. I've seen that done, where the top cup had holes in it, and was set over the bottom cup that just had a few pebbles. The person lifted up the top cup every day to give it more air.
Just FYI, I tried cotton, cotton pads, loofah, and just leaving the seeds in water to germinate. Everything got moldy and killed my plants. They were covered in foil and had zero light access. However, as soon as they were exposed to light, the algae killed my little baby plants by the next day.
Glad you were able to work with cotton. I wasn’t able to.
Thats Tatsoi, not Bak Choy
What was the temperature when you were spouting the seeds? Thanks! ☺️
I planted some basil in cotton balls. But the basil doesn’t seem to be growing. I don’t see any roots. The plants are only like a 1/4 inch tall. The basil that I started after the cotton ball ones art much bigger than the rockwool ones. Not sure what’s happening!
Thanks for sharing. It's all about experimenting, seeing what works and what doesn't – we learn and go from there! Thanks again!
I actually went in the opposite direction and purchased a set of six 1/2 gallon mason jars. The idea was to compare growth of lettuce and other greens against that of the growth in quart jars. The larger jars have the same sized opening/lids as the wide mouthed quart jars so 3" net cups can be used for all. Still procrastinating
I get excited whenever I see you post! Thank you for taking the time to do this.Very well explained! Looking forward trying this.
It works best with soda aluminium cans and 2 inch netcups. The netcups fit in snugly, there is ample space for the roots as well and no fear of algae so no covering required. Just give it a try once.
