tempted by S-H. glass jars ok? supplies in NYC?

Hi

I rescued a Lc Angel Love in water culture. 5 dollars for an orchid that had just rotten roots. now i see green roots' eyes and new growth.

I wonder if water culture is viable or if it is better to switch to SH.

Anyway I wanted to try with lava rock. It was available at the Brooklyn Botanic Garden but now they are out of it.

There is an Hydroponic store way out in Queens. seems that is hard to get this stuff at Lowes or HD.

Also I can use the deli soup containers for the medium sized plants - but for the smaller ones I could use clear plastic cups but they are ugly.
I have nice empty glass jars but I could not poke the 2 holes in it.
is it essential to have the 2 holes on the side?
if I just fill one inch of water with no drainage wouldn't the water evaporate or be wicked upwards anyways?


thanks
