GanjaFarmer101 This is more for a personal record - but I will try to add as much info as I can:
Semi24 - Cookies (autoflower)
First time growing this strain and very impressed. I have never heard of this company before and was expecting low or average yields, but this one has surprised me - nice fat plants, great terpnes.
Temperatures between 30C and 38C for almost the entire grow this year - so, very, very. hot.
Solution for extreme heat? Misting all the plants in the evening (or early morning) with water so it's like we've had a light, cooling rain. This is the key to making sure the leaves don't suffer the heat. No yellow leaves at all - which is very rare. A gentle soak around the entire plant (knowing it will be baking hot the next day and dry up instantly)
Try to keep them shaded against a wall - Ideally no more than 8 or 9 hours in direct sunlight - if you have a big cluster of plants, bunch them together to create shade lower down. Also essential
Nutrients started after about a week and a half in veg.
