My daughter is 3. She’s very curious about everything, particularly plants (my wife is a big fan too). I’d like to grow some carrots in agar; this would hopefully give her a view on the development of the plant and root system. Ideally, I’d like the agar to be clear, so as to observe this easily.
I have purchased some agar from a health shop and mixed it and filled up a glass jar. The resultant “rubbery jelly” was semi-opaque, which spoils the effect. I’d ideally like to have a completely transparent medium.
a) Is there a growth medium I can use that is mostly transparent (without delving into expensive hydroponics!) - maybe a different source of agar?
b) Will it support vegetable growth (rather than bacteria/mould like most lab culture media)?
