Today was about 27C, the next 10 days is forecast to drop down to 23C. Around mid April when I will harvest the Mango Sherbert I expect the day time temps to be around 20C. But the 3 sativa I am thinking I will harvest more likely early May or possible mid May when the temps will surely be cooler and below 20C. Yes there is something to be said for cooler climes, it can bring the colours out, and my capsicum plants which have struggled with the heat of summer are now suddenly throwing out lotsof capsicums. My main wish here, is that the weather remains supportive of my grow, we haven't had rain for 20 days, and I don't want loads of it now.
Speaking of terpenes evaporating, 2 years ago we had a hot spell after I'd harvested and the concentrated smell of terpenes that seemed to be spilling out from under the door was intense. If I can manage to bring the sativas safely to harvest at least the temps will be cooler when their time comes.
Thanks Tim!
A little while back I actually measured the temperature of the stone tiles of the balcony which absorb and radiate back the sun's heat, the thermometer topped out at 50.5C or 122.9F. Of course now with their canopies covering there is little sun hitting the stone tiles.
For sure, plants can be under stress when various environmental factors have departed from optimum, but cannabis is a very hardy and adaptable plant. Some of those stresses like drought, can cause the plant to increase it's THC and general oil/resin content, just like some culinary herbs like rosemary can do the same. So the stress of a shortage of water can be used to our advantage, stone tiles too! But it is best done during late flowering. Just for shits and giggles, here's somw pics of a couple of balcony plants where dehydration occurred, when they were left without water in the heat of summer for a week, you can see there is a lot of the paving stones exposed and I have no doubt the temperature of the paving would have also reached a similar, 50C/122F in the heat of the days with no water. They look pretty crook there, close to being terminal, but they did recover on being watered, and went on to give me close to 20oz from memory. So they can take a lot, but everything has a kryptonite point, I was lucky that time in avoiding it!
This is them near harvest time
Well that made me laugh. As an outdoor grower, the first 3 pictures show one of those times when I did actually mind! It was my worst fears when I saw them, but they recovered, so thankfully our favourite plant is a hardy plant!
