Heat

@budbandituk Great thinking mate it will work fine any extra airflow pushing the heat upwards and out of the grow area is beneficial

Your Plant looks chilled to me, nice green and no cupping leaves. As long as you keep humidity high Girls gotta get it well. Feeding kelp helps them to get through to. I agree that lower temperatures are much better, but its the question how warm is it=?. iam checkeing back the temperature with a laserpistol. This pistol iam pointing at the Plant. And most times it shows alower temp than my thermometer shows. I hope your remedies work, to have it cooler for the darlings Ah stop remedy nr. 1 is... reduce the lighthours, and then see if you have to do anything else

30 degrees is fine...Did you check your leaf temp? You're probably at 27 degrees. Plants metabolise faster in that range so it's more beneficial to keep things as is. Unless you're running into humidity problems than an extraction fan is a good thing. Check out my current set-up. It works really well for Co2 bags. I run two extraction fans that duct from the centre of the tent. Meanwhile I have the bags on the sides where the Co2 sinks to an oscillating fan below that blows it into the underside of the canopy.

I’ve put a co2 bag in there too
