Hello all, I’m in the final weeks of flower for my plants and am struggling with temperatures in the tent at 29-32C. Ive noticed that trichomes are very slow to develop on both and the RQS Critical that is supposed to be ready at W7 in good conditions is already heading into W9 and still 50/50 clear / milky and I’m guessing that heat stress will have impacted trichomes development and THC %. Even though Im at final stages, I’m about to switch from daytime lamps to nighttime light periods; tbh I should have done so a few weeks ago.
Anyway, I was wondering if anyone else has had similar concerns or problems due to these near constant heatwaves?
We have some people with a lot of good knowledge here in the community, maybe some more will come forward.
Until then, what I can tell you is that in my opinion, it generally makes sense as an indoor grower to let the plant’s daylight cycle run overnight so that you have more pleasant temperatures in the tent during the warm day.
Should you have the possibility to precisely control the humidity, keep it at a maximum of 58% but no higher, as you are already at the end of flowering. This helps the plant to cool itself a bit. And, place a fan below the lamp, pointed upwards, which blows the heat away from the plant instead of towards it.
An air conditioning unit is very expensive, I currently cannot recommend it .
Thank you. Good advice. It’s already better with the daytime period switch. Using the clip fan higher is a good tip too. Another I’ve found is to place my small dehumidifier outside the tent close to the air intake to reduce heat coming from the unit.
@SmartPlants gave you my first tip already with running the lights at night, that is the biggest thing I change for temps getting high and you are absolutely right about the dehumidifier as well. Any equipment that you can move to the outside of the tent should move. Dehumidifier, exhaust fan, stuff like that, they all add small amounts of heat. The other thing I do when its really hot is i start to add extra co2 and a little extra nutrients, the combination of that helps the plant make the temps more usable and less stressful.
It would be best not to have any plants in flower during warm days. For two consecutive years now, I’ve had problems with bud rot, caused by the heavy sweating of the buds. With airy flowers, it wouldn’t have been such a big issue, but they were rock hard, which prevented the moisture from evaporating from the buds and thus created breeding grounds for mold. In the future, I will try to send the plants into flower only in autumn or harvest them before summer. This also helps ensure a slow drying process during the drying phase to better preserve the terpenes.
