You know they use the same thing for dogs and cats but they may have to eat it and then fleas that bite em die… spinosad must have many uses plants and animals
i have a spinosad resistant thrip. Its prolly jumping from garden to garden. Its on some seedlings now and i defoliated the leaves and gonna spray them right now with spinosad. im always doing like 5 things at once and forgot to apply the spinosad yesterday i think.

there may be a chance mine got old. i dont get thrips all the time. Il check the date.
Because geothermal is expensive af

up front yeah, operating costs can’t be near as crazy as HVAC at scale
That’s what I’m going to do. 
I had a bottle of it that hadn’t been used. Then do everyother ipm and spinosad.

thrips are usually easy to get rid of.

My father has a geothermal heat pump in his house and his electric bill is high year round from the compressor. Probably 3X what I pay easily.

this isnt up for debate anymore or at least shouldnt be, photons grow flowers and modern leds are vastly more efficient at producing photons than hps.
Last I checked geothermal was the most efficient new systems. ( Seer rating alone) If your father has a 30 year old geothermal unit then that would explain his power bill.
But as someone said the loop for geothermal is big money.
I installed mini splits in my house. My power bill dropped $100 and I didn’t have to redo the duct work.

Are you currently using led?
Any preferres led that are most popular?
Is there conditions that need tobe dialed in that are different?
yes i use led, i diy my own but im only small scale so i can build exactly what i want. you will want an off the shelf solution.
as for preferences it depends on budget, what you want from the lights ie is it just for flower or for flower and veg? do you want far red and maybe uv also? and whats available where you live.
i would look for something with far red in the spectrum but on its own extra channel, you can really shorten flower with far red end of day treatment.
as for dialing in for you it should work out great, normally with led you want to run your rooms a little bit warmer to make up for cooler leaf temps from the lack of infra red light (there is loads in sodium and none in an led spectrum). so that will ease the burden on your ac.
if you match umols at the canopy with led to your sodiums you will use less watts, so again less heat and less work for the ac.
also the lack of infra red from the led and the ac not working as hard will increase humidity.
So increase the humidity to what recommended %? Higher than 50% for flower?
And room temp should be 80ish degrees?
room temp will depend on leaf temp which will depend some what on light spectrum. but 80 should somewhere near.
a starting point to humidity should be whatever vpd tells you it should be for your leaf temp, then adjust till your plants look happiest. i would start around 55%.
Soumds good how is vpd calculated? That has todo with leaf persperation? I briefly read through some information on the gavita website
Led may be the best solution
vpd is something like saturated vapour pressure minus room air vapour pressure but basically you use a vpd chart like this one - https://docs.google.com/spreadsheets/d/1iWJ-fhgqEulmNEiasgNXsilrufUhUHF95KGjX9m5C44/edit#gid=1516385392
yer i think led could work well for you.
Iv been looking at the gavita 1930e led.
Anyfeed back on that unit. I see a lot of people using the 1700 model.?

the 1930e is marketed as a direct replacement for a 1000watt de sodium, litterally take your son down and hang that at exactly the same hight and spacing.
the 1700 is a bar light these are meant to be ran closer to the canopy but will require adjusting from time to time to make the best use of the light but should be more of an effecient way of lighting your canopy.
