Grow shed vs attic grow

I have abundant attic space for an indoor grow. However to get power water and a drain is going to take a lot of work. I live in the country so my power and water is away from the house. I have a space to build a 10 x 20 grow shed out by my power and water. This will spare me some expense. Both are secure spaces but I live where temps can reach 110 in the summer. So my attic can reach 150. Any thoughts advice recommendations would be appreciated. I am fairly handy and want to do a sealed grow room as I am growing medical with access to multiple cards and caregiver recommendations thanks

150 degrees? that in itself would be the determining factor. but, if you are dead-set on the attic, I suppose that a GOOD a/c unit could make it usable. makes me sweat just thinking about it, however.

I'd vote shed.

You could sink a foundation a few feet in the ground for a bit of ground cooling effect. Saying that, I have no idea what you're local geology is like :D Either way, you'll be able to insulate the shed well and the cooling will be a fraction of that of the attic.

Well the attic is a lot of work and sounds almost unusable in summer. I think it's biggest advantage is in stealth. You live in the country so that there probably gives you a degree of privacy without using the attic. And you're growing medical with access to cards and caregiver recommendations, so you'd be about as legal as you can get. So a new custom shed sounds pretty darned good. Maybe put some thought into how you could disguise the purpose of your shed.

Yea I am the last house on a dead end street many houses out here have small outbuildings and I may use it to enclose my well pump in a separate enclosure so stealth really isn't a concern for me. My property is fenced and gated

The shed would get nearly as hot as the attic if it were closed up.

The way you describe it, being MMJ compliant, stealth is less important, so a well insulated shed w/ A/C & heat for the winter (if you need it) seems like a good way to go. You'll need a double door system & good security. Depending on where you live, it may be very economical to contract for a basic shed, trim it out yourself the way you want.

In a big attic w/ gable fan(s) & good air crossflow, a sealed air conditioned room within a room could be very stealthy & high security other than the heat signature.

Yes I hear what u are saying. I barely get any traffic by my house. The only traffic is equipment for working on the orchards by my house. My other concern for my attic is over the garage. And I am concerned for the load constraints as it is only supported on two sides. So anything remotely hydroponic might be out of the question. I was going to construct my shed so it looks like a walk in freezer and insulated foam insulation 12 in thick and 2ft thick in the attic. No will put foam under the concrete. Have it sealed so I can basically run a sterile enviroment

I am also going to run solar panels so useage won't be as much of an issue at the shed won't be seen from the street

A nice outbuilding adds to your property's resale value. A hidden attic grow room would be something you'd have to work at to bring the house back to normalcy if you decide to sell.

She'd all the way, insulate the shit out of it. Seriously a lot more than you would even imagine. Double framed and packed full of insulation might be nice. The cost of the insulation will save you tons down the road on power (assuming your in cali, if not and power is cheap maybe just go r16 and be done with it and buy an oversized ac.

If you can build it with widest walls north and south, in other words don't build it broad side to the west. This will save you a bit as well. Maybe plant some trees where the sun hits it worst.

Can't say enough good things about mini splits in a situation like this. A window banger WILL look strange, but the outdoor unit of a mini can be disguised.

Thanks for the advice theother. That is what I was thinking. Mini splits are pretty pricey aren't they? I was thinking just a regular ac as none of this is visible from the street or the house. I have to price it out and see. What type of grow set up would you guys use?

You can do the off brand mini's for around 1k, the ones with the mitsu compressors are like 1400, but I think well worth it. I have had very good luck with them. You need an HVAC guy to purge the lines and make sure connections are legit.

IMHO this is just the way to go. Especially when running an outbuilding. Most people running rooms are actually just pulling conditioned air out of their living space, and thats awesome and all that, but if you don't have a living space connected, or if the garden is bigger than the living space can support, sealed with a mini is just the way to go.

I can tell you from experience that if you set shit up right at first you can laugh at summer no matter how hot it gets. Also the insulation is legit in the winter as well. I am kiind of assuming you are in the valley? That is hot summers cold winters. Its kind of nice knowing everything will just keep chugging along.

Just look at your power bill. If the 4th tier is like .30-.40 KWH then a mini is honestly your only viable option. If your like .12-.15 who the fuck cares, just bristle the outside of the thing with window bangers LOL.

Strategy is always gonna depend on overhead and circumstances. I like that your not too worried about absolute stealth, thats gonna make it easier. Just keep an eye on that power, this is a very expensive hobby in some parts of the country.

You can install a Friedrich Breeze mini yourself. Comes pre-charged. Excess lines are rolled up, rather than cut. Also Friedrich makes thru the wall units [similar to window units] that the whole unit is inside the room, with the ass end vented out thru a grill so it's a bit stealthier than having a unit sticking out of the building. And insulate the living crap out of your building. Good luck. -granger

Build a sealed room within the shed and use a window a/c. I have a sealed room 4k In an attic that's cooled with a window a/c 24,000btu. Only cost $300. The a/c isn't outside so I vent the room that the back of the a/c is In when it gets over 80 deg. Works well..
