They need light but not warmth so if they don't get much standing in their little pots on the floor, raise them up on something - just make sure they're not in danger of being blown over!
Did you put any stones of broken crocks in the bottom of the pots to help with drainage? If not, stand the pots on something ridged with holes in the bottom to allow the excess water to drain away. A plastic meat tray with holes made in it will do a reasonable job and the deepones will hold the pots upright too.
And yes sycamores are bad - when the leaves get a bit bigger, check them against mummy or you might be growing monsters!
