I don't think it would become like this without injected CO2.
But who knows? Anyway tip - invest in cooling. E.g. fan.

Sunfire...i would like to know your secret to such lush green HC too. Mine also melt within a month

There is no secret. Time is the secret. Given enough time, the HC that is rooted would spread.

Ok, maybe this might be the clue.

I fertilized with Aquatilizer once a week with water change, and added root tabs once in a very long while.

And don't buy emmersed HC because they melt?

I have no idea! There is no secret.
