Based on?
I ran well above this. Even outdoors our temps here easily are breaking that by june 1.
Wow where do i begin 86 degree was based on a average grower , not someone who has 100 grows under their belt , and at that temp the plants are drinking like crazy to keep up with transpiration so you had better make sure you have your ppm and ph perfect of your water or you create problems ,above 86 degrees you start to deteriorate the thc on the upper flower buds , and yes some plants will take higher temps (sativa dominate )and as for a outside grow with higher temps well think about it , there is no way outside the ppm of co2 are 1000- 1500 ppm there is more wind ,breezes and air flow and if they are 1500 ppm it is now on the verge of being toxic to humans so get yourself a respirator mask , you wont get the air flow in a tent in a house like mother nature provides outside , we we stating high temps plus high co2 numbers , and outside grown bud usually tends to be a little more airy (not as dense )as a inside grow .your plants didnt need the memo as mother nature got it millions of years ago and provided for these plants just what they needed a perfect atmosphere, not 1500 ppm of co2 we are pushing our plants to the limit , besides why would you want to push your plants much above this , is the yield that much better to take the chance of hurting your plant , i think not .fantastic job dutch on this grow and journal !!!
What happens above 86 degrees, because my plants did not get that memo.
