Can you help me figure out my mini split?

So I am thinking about investing into one so I can have cooling and heating, do they run outside of the area or do they install inside? Also I need help figuring out what I'll need, My rooms aren't completely finished not completely sealed only about 80% finished, I'll hopefully have it all finished before winter, it's 1200 sq feet or so, it's a 25x30, and I've split it in half, one room was going to be flower and one is veg but currently I am only running on room, flower, currently I have 4,400 watts going, a dehumnifer, several fans, I've got a duct 8in fan running outside that pushes it all out that is also running through all the lights and currently cooling it with a 12,000 btu ac unit, temps 72-76 and humdity I've got down a lot from before was at 70-80% now I've got it under 50% and sometimes as low as 40%, I've got 4 cycles going, some are 3 weeks, 5 weeks, 7 weeks and some over 8 weeks.

I'm curious if there is a better way to run things, I normally at night leave the duct fan off because otherwise it brings my humdity up a lot, and at night when the lights are on I have it running, but I'm wondering if I'm just sucking out my air from my ac unit even though I'm taking the heat from all the lights, should I be having it run or is there a better way to run it so it don't suck my ac up or should I just run it on a timer so it only goes on so many times a day, hour, but overall I've got everything running rather well and temps and hum pretty well finally, as I was starting to get some power mildew when it was very high before and now it seems I don't see anymore of it on any new plants, If you have any tips for me I'd appreicate it, I know I'm not running perfect, I know after this grow I'm going to change up a lot of things and redo it, and I will be adding more lights and better cooling and heating system hopefully, also I'm looking for a cheap way to water all my plants, I am looking for something that waters more then 50 of them but not looking to spend a ton of money doing it.
 
your doing ok from what i read

this is where it gets fun .......2 types of rooms
1 sealed room where u supply the co2
2 open/exchange room where u bring in cool air and Co2 venting the hot used air out of the room

tell me the one u want and i will help design u something cost effective
 
A real furnace and a central AC unit! Mini splits will KILL you on electrical costs!
1.5 ton minimum. With that use a 24K evaporator on the furnace to "cheat" the AC to be more powerful!
Best to start at a 2 ton AC unit and "cheat" that evap up to the next level!
The central AC will control the RH well too, so minus elec cost on a dehumidifier too!

This is costly BUT, down the road it's the BEST way to go!
Run the condensate pump to your water tank and put a silver quarter in the condensate pump tank to kill bad bacteria from growing in it.

You will still need to exhaust out periodically! Set up for that too..

Give me an hr and I'll provide a link to pkg deals with good costs for the hardware as in furnace, evaporator and condenser,,,,gotta tend my garden...

Ok back....
Here is the site to find wholesale heating and cooling pricing to the public...

Here's a deal on a 2 ton and it 's a well known quality brand!

Your looking at a total cost, shipping, parts and installation at near 3K......I know , I know that's a LOT of hard earned cash.....In the long run you will love it if you make the choice to.

Doc

Pretty good deal for central cooling, and only about double the price of a mini split after installation....wish i wasnt renting, id be all over this...
 
That's exactly why I went the correct route....It is sooo much more efficient!

The trick in the cooling side is to run a 1/2 ton bigger evaporator and you get significant increase in the effective cooling at minimal cost, with no added elec. increase! In fact it lowers it a bit by adding exchange efficiency ..
