Does light on my roots affect the growing??

Okay I have some plants in clear plastic cup with the roots exposed to light...will that effect anything??

you want to avoid any light getting to the roots

NO LIGHT! that promotes algae growth and you don't want to deal with that. Alum foil blocks out light but it tends to trap heat. If you have money to spend go get some black and white polyurethane. Leave the white side up to reflect light and you won't have to worry bout any light getting through

or you could do wat i did...put them in black grow bags...very cheap theyer abiout 50cents....and the smaller ones are about 25cents...... blocks out light and works fine..

Or...you could simply go buy some pots to put them in....hmmm now there's an idea...stick to what works best...then you won't have problems.

Yeah, like everyone said you need to either re-pot your plants, or use something to block out the light from getting to roots or else you asking for trouble.

light on roots bad juju! That's all I have to say...
