Growing In Hell, Literately.

(RECAP) FROM FIRST POST WEEK 9 -5/19/2018- "Growing in Hell" well close enough, I'm growing outside in the middle of the summer in the Arizona desert, but I'm currently at my second attempt in 10 years from a seed I found in a bag of gorilla glue I think #4 from the dispensary so I planted it outside and given my location in Phoenix Arizona and the summer being here now with 115 degree days sometimes but 106 degrees average daily temp with 0% humidity, so I tried an outdoor/indoor combo, which is a small green house built over the in ground plant when temperatures got too hot so I could still use natural sunlight and covered green house to black out plant to control light schedule and temperature with swamp cooler. I have no idea if anyone has ever attempted growing this way (outside in the Arizona desert planting in spring and flowering in evap cooled greenhouse during summer covering to control sunlight) but my plant has been very happy the last 6 weeks since putting in the green house up and brought the temp down with evap cooler and also importantly brought humidity up to appropriate levels just using evap cooler itself most days but added humidifier for really dry days. Since I planted the seed in mid March and with the seasons changing the light schedule was way off so it took 10 weeks of vegetation before I was happy with size to switch to a 12 hour schedule to initiate flowering. 7/2/2018- Since then the plant has been on a more regular schedule appearing to flower at a good rate maybe too fast actually as I'm now concerned about when to harvest. I can see the very bottom smaller nugs have all white hairs and I dont care as much for them to be ripe and know since they don't get as much light they wont be as far as long, but the bigger ones on the rest of the plant look ripe except for the very top crown nug is still less then half white hairs. So my question is if different parts of the plant are ready for harvest and some parts look like they could have a couple weeks to go. So when should I harvest? Can I harvest part of the plant as they ripen or does it always have to be the whole plant at one time to harvest and just deal with the few parts of the plant that aren't ripe enough. It's been difficult to tell as I think everyday this will be the day but then think it could go another couple weeks. I was thinking 6 weeks flowering is sorta too soon to harvest as I read gorilla glue has an 8 week flowering stage then again so many of the nugs look perfect and feel like if I wait any longer they will be ruined some how, and the fact I live in the desert growing in the blazing hot summer anything could happen waiting those couple weeks for it to ripen. For example if the power goes out or swamp cooler stops for some reason while I'm out, my plant's dead in 10-20 minutes tops being outside in the sun and would start baking inside that small clear enclosure, just like a baby being left in a hot car. It's already happened a couple times but I was home to catch it in time as I have a temperature alarm set to go off it goes over a certain degree. Any suggestion anyone has that would be great for when to harvest a plant with different nugs at far different stages of ripeness, some look like they are ready now, some look like they could go a couple weeks even being the same size but just different parts of the plant. I will try an post some pictures of those different parts of the plant at different ripeness but you get the idea but I guess so you can see what I'm talking about. When to harvest and the different nugs growing at different rates and the only idea I have come up with is it could be because of the way I'm growing not getting even light or as intense of light to my plant through the day with sun filters to help with heat, because my thought process was, doing it this way, since the sun moves the light distribution would still be better than an indoor set up but that's why I'm asking or even posting on here otherwise I could really care less to share this information, though it's good to share experiences for other growers to get information to help like me.
