First off sorry if this is posted some where, I just can't find the answer.


Hi all. A simple question I hope. Should I get my fresh air intake directly from out side of the house? I live in an area that gets really cold in the winter and can get damn hot & humid in the summer. I am thinking the fresh outdoor air is the best but I would think a "dust shroom" cap needs to be on the intake so no pests, molds or other funk gets into the room.


Thank you in advance.

Hey Evan, welcome to the thread. I'm not gonna get all the way into this but you don't need a fresh air intake unless you are using it to cool your room. That being said, if you need one then you should put some type of filter over it. You don't have to buy a shroom; you can get a sheet or two of carbon prefilter and HEPA filter from any hardware store and make your own. If you don't want a filter on the outside of your house then pull the outside air into a box you construct and then filter the air in the box before pulling it into your room.

This is going to sound really dumb, but so be it. Until yesterday, I've always had my digital thermometer on a shelf in the room. Close to the lights, but never under them. I also run my lights pretty close to my canopy. 10-12" for both 600s. I always just used the hand test. A minute or two without burning my hand seemed ok. The room itself never got over 75F.

I was actually running 98F at my canopy. So I raised my lights.

I'm working on getting cooler air through my lights, but I might be in the market for a mini split after all :(

Yea bud, I always tell people to get thermometers with probes on them and actually hang them in their canopy. 10-12" is PERFECT for 600w lights in my opinion. See what you can do to get those temps down so that you can get your lights back into that sweetspot.

My RH is really low at the canopy too. 20%.......Guess I need a humidifier.

-What are my negative affects of maintaining such a low RH?

Hi Phillip,
I'm really enjoying this thread. Here's one for you;

- Tucson area, hot, hot, hot
- garage is over 100 in summer, humidity around 15% .
- 7x7x7.5h or 6x8 home made closet, 1x1 or 1x2 framing with solid core insulation, thin outer plywood skin
- north wall against interior wall, 6" hole at base for air supply from interior (bedroom)
- exhausted through top, through ceiling into attic
- outward opening door on south side, 4' wide, full height
- (I think) 4x400 HPS for four larger plants at a time, for flowering - this is very flexible. Organic. More plants initially before sexing and maybe some smaller cutting plants (from topping) squeezed in for quicker harvest. Lumatek Ballists on exterior top of closet, can also be tuned for 250 watt and/or 25% energy reduction. 6" air cooled sealed reflectors
- seedlings and vegging (400 MH) in the garage for now, also vegging outdoors
- using Mandala Seeds, which are developed to handle high heat and low humidity, they seem to be living up to claims. Garage is currently 88 degrees and plants are 6 inches from reflector glass and loving it.
- trying not to use a portable ac but will use if I have to
- ro water, teas, all organic

That's all I can think of, whatcha think?

Hey bud, thanks for stopping by. I know the Arizona heat well my friend. Lived in Scottsdale for almost 5 years.

Sounds like a great plan. Couple things...

You are gonna need a/c in there. I'm almost sure of it. Get everything up and running and see how them temps do before you put plants in the room but I'm pretty sure that 6" intake fan from the bedroom isn't going to cut it. The ambient heat in the garage is going to make the room into a sweat box. Look into ways to vent the heat from the garage. This may reduce your cooling needs in the room. 88 is really too high for those plants. Do you have Co2 in the room? Even if you do you should look into a dual hose portable a/c or a minisplit for the garage itself. If your seeds are doing fine then that's great but I think the whole point of indoor growing is to get optimal conditions. Plus, in the future you may want to grow other strains.

Where are you venting the lights to? The garage?

Use 1x2's to frame the box. You want an uneven shaped board when framing out a room. The 1" becomes your stud and by having it 2" thick you create a stringer support and a deeper foundation to drive your nails into for the plywood.

Sounds like you want to grow larger plants. If you are going over 3'-4' tall with your plants then I would suggest a higher wattage light. 400w lights are great but they will not give you the canopy penetration you need on taller plants. Either get higher wattages or grow more 3'-4' tall plants. At that height you can fit 4 under each light.

They are designed to handle 100+ degrees but I'll get the ac.

Venting to the attic.

How about T5s(coral bulbs etc.) or some other side lighting instead of 600s? I do like big plants- cant' help it, I'm a horticulturalist, lol. But I would like to have versatility as methodologies may change, after all, production is the main factor. Just trying to use less plants for legal reasons (24 total plants). With that in mind is the 7x7, as opposed to 6x8, the best option?

Thanks

Also growing two outdoors in 50 cubic foot planter with shade cloth.

I don't have any experience with the coral bulbs but I know there are some threads in the indoor growing section on it. Check the fluorescent sub forum. I use uvb and vertically hung mh bulbs but i have a much larger room. Any veg spectrum supplemental lighting in flower will always aid your grow. Even hanging veg spectrum CFL's will help.

Design your room to your light footprint. If you are going to be using 400w bulbs then they have an optimal footprint of 3x3 when 6-8" from the plant canopy. So if you did 2 rows of 2 lights on either side of the room then you would have a 2' walkway in the middle. Sounds like 6x8 would be the route to go.

Hey I need help with a closet design. If anyone could help me out that would be awesome. I grow using rubbemaid tubs for my res and my plants. Here's a pic of my room right now.
