Cactus farm not growing!!

[Alex]

I need help on what I'm doing wrong. :(

[Alex]

Its in a area with wood blocks on the side and sand beneath it, 1 thick. And it has torches around it to grow but it hasn't grown. Its been about 7 minutes. I gave them about 2 or 3 blocks space to grow each cactus. But still, no :(

Wait longer.

But other than that, I've made a cactus farm by having 1 layer of sand set out on a long path in the air, which was held in place by a block that does not fall (such as stone block). Let's say that path is about 20-50 blocks long or however long you want to make it.

You can then make another similar path about 10-20 blocks above, and make several similar rows. You'll get ant lions, vultures, and cactus, prickly pear, etc. I haven't seen waterleaf growing naturally in my cactus area, so I plant waterleaf separately in another garden.

Pictures would help us help you find out what's wrong.

I can't get cactus to NOT grow.

A screenshot of the cactus farm might help us to figure out what's wrong.

From what I'm reading, it sounds like you put the wood on top of the sand, but I know that can't be right.
