Close call but next time just make sure the plants have good circulation by blowing air right on them. Just like people when it's hot we need a fan. Also, raise the light as high as you can so the canopy doesn't get too warm. Consider this, Aussie's grow with no A/C and it get's hot as fuck down under but they grow some huge bud's. If you ever looked at any of their grows you'll see a lot of circulating fans. What many don't realize is that weed loves hot weather and will grow wheater hot or cold.
