I am. The thought of them keeps me up at night. You're the man deadgro, appreciate the advice!

I'm growing out 3 AK48's in a 2x6x8 closet using 3 Platinum P150 leds. I'll be adding my scrog screen in another week or two. I found 3 60w led grow flood lights on clearance and will add them in flower. The were only $22 shipped, 9x1w blue, 3x1w white and 48x1w red. I know they are cheap...

Hey jonjon, I think that you should start a new thread. Title it "How many BTU's do I need?" or "How much ac do I need?". Then give all of the specific details and ask for input. The details you need to provide: lighting (number, type, watts,are they vented...), grow area size, grow area...

Sorry, I can't help you there. I've never done a heat load on a grow room. But I'm sure there are lots of people that can help if you give them all of the details.

Oh, and if you are going to diy the install...remember you have to pull a good vacuum on the line-set. I also always insist on pressure testing the line-set with nitrogen to ensure there are no leaks...flare fittings suck compared to brazed line-sets and you want to ensure that you don't have...

For mini splits I recommend Daikin and Mitsubishi, but they are usually at least twice the cost of that unit. From what I just looked up, Blueridge seems to be a re-branded Gree. These are relatively good units for low-cost options. Keep track of how your existing unit does with the heat and...

I don't like them because typically the unit is in the same area that you are trying to condition. Even with the exhaust, this adds to the heat load = counterproductive. They are also usually very cheaply made. You have to empty the little condensate drain catch, which sucks. Many of them...

Ya, it actually generates O3 molecules that eliminate odors. I did lots of research on them before setting it up. Lots of pros and cons. Most people disagree with running it in an occupied living space. After lots of research, my opinion is that its ok as long as you don't generate enough O3...

I wouldn't run the line back inside. The condensate pan is outside already, so re-routing the drain line back inside won't keep the waste water from being outside to begin with. It would be a pain in the butt, not accomplish what you want and asking for water damage. I think you are going...

If you have a trained drug sniffing dog set to check out your house I think you've already lost the battle. If the cops have a tip about you they can get their dogs to make a "hit" whether they smell something or not and in they come. And those dogs can smell through walls.

I usually put foam board in the entire window and foil tape it in place and to the window unit. This stuff is fine: http://www.homedepot.com/p/Rmax-R-Matte-Plus-3-1-2-in-x-4-ft-x-8-ft-R-3-2-Polyiso-Rigid-Foam-Insulation-Board-754404/100572981?N=5yc1vZbaxx The thicker the better. But most...

I don't like that plastic. Go get yourself a bucket of mastic sealant http://www.homedepot.com/p/Speedi-Products-1-2-Gal-Water-Base-Duct-Mastic-Sealant-AC-DMS-0-5/202907021 and a cheap paint brush and go to town. This one small bucket would have saved you all that caulk and silicone spray...

I'm still not understanding. There are really only two refrigerants used in typical residential air conditioning applications: R22 and 410a. Of course, there is a slew of new R22 replacements, but you will not find a single new ac unit sold with anything except 410a in it. I've worked on...

Don't cut the fan off in the rear! You'll burn up your compressor :)

Caulk and foil tape are your friend, for both light and air sealing. Mastic sealant is the way to go for anything permanent. It's messy to work with, and a beeotch to remove...but that stuff is a true permanent seal barring physical damage. If in doubt, a simple smoke test will let you know...

Window units don't exhaust hot inside air to the outside. Inside air is sucked into the unit, passes over the cold evap coil where heat is taken out of it, then blown back into the room. Outside air is sucked in, passes over the hot condenser coils then blown back out. The two coils are...

"New refrigerants don't work in extreme heats or colds." Can you elaborate on this?

My seedlings were in 16oz cups for a little over 3 weeks in FF Light Warrior. Transplanted to FF OF/HF/perlite mix in 1g smart pots. They've been in the 1g pots for about a week and growing great. I haven't added any nutes up to this point, other than a 1/4 dose of cal/mag in their last...

This device will solve your problem. Fully programmable and works with heating and ac. I know it works because I own one. Run a cord to this, place it in the space you want conditioned, then a cord to your ac. Turn your ac down as low as it goes, and this device will kill power to the ac...

They are talking about mini-splits. These units aren't cheap, but are very easy to install. They can be anywhere from 13-28 seer, but with your low cost energy you might just want to stick with 13 seer. Most of them are heat pumps, so you have cooling and heat. No duct work to install, just...
