Correct, purple comes from both strains and temps. For instance, I used to run purple gorilla indoor/outdoors. It turn OMG purple reguardless of temps. Both leaves and the actual bud caylaxes. Now on the other hand, my jack herer will turn purple if night temps are in the 60s. Generally speaking people breed to get colors. I used to run a landrace sative called kiwi. It had no joke, pink hairs and pink buds. no white hairs. they were pink, and when plant was done they turned deep red. Was a very pretty strain, but it took 13 weeks to flower and wasn't on par yield wize. I do like purple strains, and people do go nuts to get purple bud, but usually the more purple it is the less it yields or the less potency it has. I have yet to see a high yield color changer that has good potency. 2/3 is the best you usually get lol. The kings kush I ran outdoor was probably the closest I got, 50 gallon trash can netted me 6 pounds of dense sticky maple syrup flavored purple buds. 6 pounds is a good amount, but similar sized plants gave my 8 pounds.



Now then, as for my outdoor this year. Picture 2-3 10 x 20 carport greenhouses line up together, 12 plants per greenhouse planted in 4x4x4 holes. my main greenhouse plants are already in 2 gallons topped 10+ times supercroped trained etc and 2 footers....so ya buddy, strap into them seats, its gonna be a fun ride! I am prob gonna run my blue cheese and jamiacan dreams outside no greenhouse (READ: SUPER MASSIVE). They are super quick flower times so they should be done before the frost hits. i am expecting 150+ pound this year outdoor. LEts all cross our fingers !
