i need 30 plants!
10 per irregular.
10 for organic fertilizer
10 for inorganic
and 10 for no fertilizer
to see which grows taller within a month.

egg cartons are suitable because i already have them, glib to carry around (their adjectives attached) not to big, and will look cute

but will i be able to put the fertilizer surrounded by easily satisfactory?

and for flower pots won't i need A LOT of seed?

which should i use?
When should I plant my Bearded Iris rhizomes?
Answers:    by the end of a month, your egg carton may start to break down. Grass seed is dirt cheap, and I wouldn't be surprised if a garden hub would give you some used 6" plastic pots for free if you told them it be for a science project. If they want to sell, don't settle up more than 25 cents per pot - they'll be making a profit on that as it is.

Your plastic pots should also have the volume of soil that they hold stamped on the bottom, which will hep surrounded by making accurate fertilizer calculations.

-actually, if you own to transport them, ask for cell packs beside trays, not individual pots. that's the type of thing that annuals are sold contained by.

Egg cartons are too small to contain satisfactory soil to allow your seedlings to attain big enough for your experiment. I'd suggest small "starter" pots that you can procure at most nurseries. They're usually 1.5 - 2 inches across; shape doesn't matter, although square pots can be easier to matter with contained by large numbers. To receive them look nice, just bring a seed flat (which you can also return with at a nursery) to set them in to transport them around when you need to.
