2x2x4 yield expectations?
I want to use a 2x2x4 tent, growing (Gorilla Cookies) autos in Nature Living super soil mixed with Coco Loco. I want to yield just a few high quality ounces. Is this easily achievable with one 3 gallon pot under a SF-1000? Should I be concerned with any plant height issues?

Temperatur
Hello, just a general question about the temperature during the flowering phase. Right now, I'm only getting 24-26 degrees Celsius during the day (more 26 than 24) and a maximum of 21 degrees at night. Is that sufficient for the ladies, or do I need to take action? They are showing no signs of illness.

I don't really know when to switch the veg light to the bloom one... the manufacter manual says to turn on both lights in pre-flower stage. What do u guys think? I also lowered the light (200w output) from 67 cm to 60, is it ok? (LED Viparspectra V 450)

Currently my lights are on a 18/6 schedule, from 6am, until 12am. I want to change their light cycle to start at 4pm and turn off at 10am, so the heat of the light balances the chill of the night. Whats the best way to do this, without triggering flowering, or stressing them.

Mars Hydro FC4800 vs FC-E4800
FC4800 = 2016 samsung diodes| 2,8 µmol/j |1347µmol PPE -- FC-E4800= 2646 bridgelux diodes | 2,7 µmol/j |1328µmol PPE Both are 480watt lights... Is there a difference between µmol 2,7 and 2,8 when it comes to yield? Is the FC4800 worth the extra money? Doesn't cost much more

Schould i buy another more expensive lamp with more watts or can i just buy a second xs 1500 ?
Does it make sense to buy another Viperspectra xs1500 with 150watts? So my question is, if the power of 2 same led lamps add up together?

Woke up this morning and she’s grown a bit from yesterday. 4cm tall now. HLG 135 was dimmed (to a level that was comfortable to look at, I have no way of measuring output right now) and is 26” away. I know it’s early but I have no experience!

Mars Hyrdo TS600 - 100w but mistook for 600w
I've recently found out that the led light I have which is a Mars Hydro TS600 is not in fact 600w and is actually 100w. Do I need to compensate in any way? My plants look healthy but short, I don't want to put the light too far away that it's ineffective, how close is too close?

Thank you guys! for watering, I don't know how she can react giving her more than 250ml. I can try but I don't want to drown her. For the light, unfortunately direct sun light arrives from 11.30/12 am to 7pm. Before it is covered by other buildings behind my terrace.
