Newbie Questions about my mega farm ebb&flow system

Hi,

I am new to hydroponics and decided to buy a Mega Garden system by HydraFarm to get started on this learning adventure. I have a 4 tube T5 fixture inches above and have a couple of questions:

How deep do I place the 1.5 inch rockwool square? Will the hydroton draw any of the water upward beyond the level which the water floods? If I placed the rockwool so that the bottom makes contact with the very top of the water, it seems like it would be buried quite deep when planting something like lettuce.

Thanks in advance.

The hydroton will draw it up and the roots will quickly expand downwards.

What is your concern?

Thanks for the reply. My concern is the roots not getting enough water initially if planted too high OR the roots getting too wet if the rockwool is getting drenched and holding water.

Since my initial post I have placed my plants just above the water line and they seem to be doing fine.

Pics?

The air coupled with the remaining moisture should be fine and will not drown them unless your fill times are too long. It doesn't take much moisture to get those roots penetrating deep.

:D
