few mixed beginner questions. thx in advance

[IndoorTropics]

1) For a 10-11 week auto from sprout, when is the last day you would foliar Spinosad or Neem oil? (i def dont want to confuse info for photos with autos here. quality over quantity for sure)

2) Which pots do roots prefer? Wide and less deep? or deep and less wide? Or as expected little to no difference? height wise, shallow and wide is nice but for soil bugs etc deep and less wide is best maybe?

3) for a 10-11 week auto from sprout, when EXACTLY in the flowering period is it most important to keep RH under 50%? I understand the final 2 weeks, but what about the other flowering weeks?

1)same as with photos
2)taller thinner
C) google vpd chart and follow it ;-)

But of course someone might have different opinion ;-)

1) So spinosad up until day 35 from sprout is fine for 70-80 day autos?

2) thank you. makes some sense.

3) seen VPD charts. Looking for a more specific answer, anyone experienced can chime in?

I would probably stop around week 6 or so.

I use square pots that are deeper than wide. I've used regular fabric pots, I think it matters more how you plan to water them. Top feeding, bottom feeding, dwc, aeroponics, etc.

They referenced the VPD chart because it can give you a general idea of what environmental parameters you can try to keep in balance. Some people won't even have have 30% the whole grow and it's more than staying around a certain number. You don't want large fluctuations in temperature or humidity and a mild airflow keeps microclimates from becoming breeding grounds.

This website has a chart for environmental conditions. The colors refer to the plant stages/extremes while the left and top contain humidity/temperatures. In a general sense you could flower at 95f and 75% humidity while being fine. Usually though you'll probably sit at 77-84f so a humidity of 50-60% might be harmful but it's strain dependent too.

That website has temperature offsets from 0-4f. You need an IR thermometer to be completely accurate and measure the leaf surface temperature then compare it to your ambient temperature. 80f ambient with 77f surface temp is a 3° offset and there is a chart for that.
