Thank you for the really easy,direct cheap way of doing a compost bin ( iliked the idea of screen instead of drilling small holes only) i have two question as i am new for composting:

1- what about the bottom of the container ( should it be a gap like with no bottom as we put the container in sand or we keeop the container as a whole with a bottom with holes and screens?

2- till now i ddnt do a compost bin however i do have food that needed to be thrown so for how long the food that i wanted to throw can wait until the compost bin is ready??should the food (fruits vegetables) i want to throw be "fresh" or is it ok if it was 1 to 2 weeks old?

thank you in advance.
