ok thanks a lot...Goodinfo.

I dont hydro so I didnt know.

However....

These balls are not suited for top and alll me to tell you why...IN MY OPINION...

Whe watering, these balls will absorb a lot of water.

The as these clay balls dry out, they will draw water from the soil surface, causing faster dry out times meaning more water is needed than normal.

Also, since these rocks hold water, the lights will cause a high humidity / evaporation rate, which could be seen as steam if you looked under a microscope.

I agree a V sign is or can be a sign of health. But, the tips are burned and the one plant isnt a V....its almost folded closed.

I will go on record as saying...

Remove the balls, add more air movement, water more and you will fix your problems.

The clay balls?

I say the they absorb water, but, when dry, this is not good for the plant and the leaves are reaching skyward to avoid the clay balls.

Plant leaves do no like to touch ANYTHING....anything....and will either grow away from what they dont benefit from or discard what it is that is causing the discomfort.

I stand by my advice in my original "If I Were You" post.

Good Luck.
