3000 watts in the summer?

[stayboatin.]

would 3k in cool tubes with an intake from an air conditioned house stay cool in 90-100 degree summer days? how many cfms are we lookin at too?

I would think an 8" vortex would do it, but don't run them in series.

3K stand alone would require basically 3.4 btu/h cooling capability, or more clearly explained, an AC rated at least 10,500 btu/h to offset the heat generated. Don't forget to add up the other heat generating devices such as air circulation fans, inline intake/exhaust fans, humidifiers or dehumidifiers and the like when calculating your cooling requirements. The answer to your question is MATHEMATICAL in it's entirety.

In addition calc's need to be made with reference to heat infiltration from the outside summer temps.

In short, it is highly unlikely that you can maintain the "sweet spot" temperatures that you seek without having a dedicated AC for the grow area. In my setup there are 3600W of light (6x600) plus a dehumidifier for use during Bloom (400W), plus one 30" commercial grade stand fan and 3 inlines.

In place is a 12,500 btu/h through wall AC, just for the main grow room. No Problems......none at all.

It's all in the Math,,,,,,get it right from the git-go and be comfortable.

now with over 3 thousand watts. do you need a circuit breaker dedicated to that to hold the amount of watts needed. or would your basic master bedroom have enough power to run that???

I use a 10000 btu added to the main room to reduce the work of the central ac to reduce electric use and to also act as a dehumidifier for the main room I have 3200watts of light. this summer I am not going to run the upstairs room because last summer the cental ac ran nonstop to keep temps down 90+degree days are not uncommon here after May
I agree with ty stik once you also add the water pumps the fans the lights It would be really difficult to keep operable temps with out ac
I have for the basement the main room in the summer a 60amp auxiliary breaker box with 3 20 amp breakers the same upstairs I do not use any of the existing wiring in the main flowering rooms it is all very old electical knob and tube. I would recomend new dedicated breakers for any high electrical use areas I probaly do over kill for peace of mind I am only there a few hours a day and sometimes gone for a week

No, your basic bedroom breaker is rated at 15 to 20 amps. Each 1000w ballast wired at 120v will be pulling around 9 amps each (27 amps total for 3000 watts). You need to dedicate a larger breaker (and line) and/or re-wire your ballasts for 240v (if your ballasts are multi-volt) so they draw 1/2 the amperage (bout 13 amps total for 3000 watts wired at 240v - give or take an amp). Keep in mind that this does not account for your ac, dehumidifier, fans, pumps and everything else that requires electricity.

nice numbers on the 3k.
my 10500btu a/c holds my room at 85-day and 75-night. but only barly.
working with a 6" S&P fan with 3 hoods inline.

thanks for the info..
i still need to pick out my new house..
so once i do illll take pics of the room man and breaker..
and fig it all out to the detail!
