I think your LEDs will be too close. You need a little distance between the LEDs and the screen, or else they will be too intense and you will get no growth. Otherwise, looks pretty good!

Welcome to the site!

Welcome.

I can see that your LED is spread out across the sheet, so it can be near and less concentrated. Probably will work.

I cannot see how the bubble escape.

Thanks are reply.
Now I get to know your point.
Thank you very much.

But in case, I had 90% completed this model.
So I will test it one month.

On my the other hand, I will modify the led position to continue the test.

I still think the LEDs are too close. Do you have a pic of the front side of the LED fixture?

Looks nice.

The foam on the top will help stop salt spray.

The airstone should be covered to block light.

The airstone should be all the way across (you might want to use cut-air-hose instead).

The screen needs to be very rough.

Probably will need more LEDs to cover whole screen.

Your LEDs are too close and therefore too intense. I guarantee it. You will get zero growth in front of the LED and for probably at least a 1 cm radius circle around it (that's 2cm diameter). You need distance from the screen for the light from the LED to spread out.

I agree with Floyd on the LED distance, its to close.
