Adjustawing vs air cooled, which is more efficient?

2 part question , first electricity , which will cost more? For example let's say I have 2 1000w hps in nonair cooled reflectors with an AC obviously, cooling the room. Vs same 1000s under aircooled reflectors with an 8in fan sucking hot air? I would need an AC anyway in this setup to keeps temps down... correct? Maybe not on winter time but def in the summer...

2, results, air cooled will allow me to keep lights closer but the closer the lights the are the less the footprint... so the edges of the 4x4 or 5x5 footprint will suffer ...


I'm planning my future growroom and want to above anything, have it separate from my home, I don't want ducting running g out of a door.... even it will heat an outside room,heat would still be used, lights r only on 12hours..

Any help would be greatly appreciated

the cost would be tiny, the fan would be the only diff, so if the fan is 100 watts then over 12 hours it would cost you about 10 pence(or whatever you are charged per kilowatt for electric) however if you use a coolshade then the AC wont have to work any where near as hard/much so wont be on as long, saving you money.

air cooled all the way

You also have to factor in the fact that you lose light efficiency when shining it through the glass of a hood. Lets say for arguments sake it could be up to 5-10% light loss?

from what i remember reading from the bible doesnt the adjustawing have the best light spread?

i guess so, but that same amount is gained back or more because the lights are able to be closer, inverse square law

i just went through that chapter, yes it does.

air cooled it is. i planned on doing 4 plants per light, but i just read over the bible and it says 3 600s deliver more light than 2 1000s. 3 points of light, closer to plants and bigger footprint.
12 plants or 10? i wanted to hit a pound per light with the 1000s, with 600s is that possible? without using a scrog that is, i like mobility.

I used to run non air cooled lights in a very tropical non medical state 6 1k's and a 4 ton central AC. That 4 ton would blow non stop when those lights were on. My electric bill was only 400 (no one lived there). I miss those days

Since i've moved out west I use aircooled lights. I brought that same 4 ton AC with and still use it . I don't use it have as much now even with a co2 generator running.
I have total control over the temps in my room now. Also helps with the power bill. Cali electric has to be the most expensive in the country.

Go aircooled. That way you can control temps better and you won't need to use that noisey AC so much. But if your using a wall unit it will probably run non stop anyway. Get a 1 or 2 ton mini split if you have a 6-8 light room running

Id say Adjustawing all the way.

Believe it or not... the glass on those air cooled reflectors filter out a lot of light. Then if you even have a very thin layer of dust on that glass, then your loosing even more light. Also the glass is known to filter out most, if not all of the UV-B rays. UV-B rays are known for making plants pack on more trichomes as a natural plant sunscreen.

I have a bunch of Raptors and I remove the glass from them. No ducting, means no ventilation fans. You just need a decent Split Unit AC, set to energy saver mode and your good to go. With air cooled... you have to run the vent fans to keep them cool and most of the time you still need to run an AC to keep things at perfect temperatures. I think its MUCH easier to control your rooms environment with open reflectors, over air cooled. Air cooled... if its hot outside, then your reflectors are going to run hotter, changing the temp of your room. If its cold outside, then the temps gonna most likely go down in your room. With open reflectors and a split unit AC, the reflectors are always going to produce the same amount of heat. So you set your AC accordingly and every day your temps will be the exact same and on point.

So I would go with the Ajustawings.

very nicely said.
is the installation very difficult? i love hands on experiments but theres some things i just avoid and leave to the professionals, like electricity.
what brand do you recommend?
