Temperature problem help

[ypgypj]

hi dears. I need help urgently. To reduce light loss, I covered the inside of the cabinet with foil. but when I do this, the inside of the cabinet is over 45 degrees. auto genetics, super lemon haze fem, 16days. how much degree can my plant grow healthy? they look good now, but it's too hot here.

Get rid of the foil and use flat white paint. It reflects better than foil.

The inside of the cabinet is already white color. I made a big mistake. I will get rid of the foil immediately

Good idea, Not only does it not perform as well as WHITE PAINT (Hospital Operating rooms are painted white)
there is the issue of moisture,darkness and heat behind the foil (mold)

Why does mold grow better in the dark?

Mold grows well indefinitely in the dark when other environmental conditions favor its development. In warm areas, mold grows faster in the dark, where increased moisture means a higher relative humidity.
