Hmmm peak summer in real life is very difficult to push hard during flower indoors I fond at least, electrical cost of providing adequate cooling can be a pain for a home grower,
In cooler months with the extra ppfd/temps I can pull anywhere 5-700grams from 2 plants in a 4x4 over a 12 week veg. Not sure I'd have been able to do that in summer.
The biggest problem I found was preservation of the trichomes and terpene profile, the heat generated quickly wipes put the smell.and often the flavour if it's over cooked or regularly has 90+ temps or you lose a fan for 2 days without noticing and run 100f doh.
Guess it's all about expectations, how well you control your environment will dictate what you are able to yield. Controlling environment in summer costs a hell of alot more, if money is no option then I salute you sir, but if it is then jist try take it easy, cool dark basements can help so long as it's kept humidified, so long as you can stick to parameters you set its all good, thay one day it's 40 degrees outside and you lose a fan n half the plant hermies from heat stress. If you can keep things reasonable expect same yields as any other time of year.
