how deep do i flood in an ebb and flow ...??

[zoomatl]

I'm setting up my ebb and flow table and need to know how deep to flood ...i have 3x3 rock wool cubes that i will be putting in 7x7x10 inch planters with grow rocks...how far from the wet rocks inside the planters do the rock wool cubes need to be ......the bottoms of the 3x3 cubes have roots just starting to peek through?:D :confused:

You need to cover all the root and the root ball with every water. Make sure that no light can get to the roots or you will damage them.

You need to have an over fill tube to set the max height your water will run that way the extra will just drop back into the res.

Just keep the light out and you will be fine.

so put the rw cube in so the bottom touches the wet rocks or boes it need to be submerged a little...?

The bubbling action will provide water as the bubble rase and pop. You can put them at the bottom of the net pot then use grow rocks to fill in the holes. You don't want light to get to your roots period.

This is all assuming you have a viable seedling at least.
