Air conditioner

Air conditioner

Has anyone tried one of those portable airconditioners ( the kind with an exost hose that goes out a window)in there larger cab, you would be able to keep the temp as you like also the humidy ,Might also use less electic than a bunch of fans also quiter

 

[Pipedream]

With a portable airconditioner, you still have to exhaust the hot air someplace. Usually its done with a hose that leads to the outside of the building. If you just exhaust it into the surrounding room, you'll raise the ambient temperature. As a result, warmer air will be entering the intakes on your box. You'll likely gain a little, but not much. If the exhaust air can be run thru a good scrubber first, then outside, you've got a winning situation.

I don't know if you would need a surubber on the exust the air goes though a heat exchanger and only cools the heat pump , hose could go out a window across the room or through a cloths drier vent, or heat an other room during the winter, if you want to spend more money and are handy there are water cooled
commercail heat pumps that are uses for walk in refrigerators

A couple of thoughts;

If you're running out the window why not run a window a/c unit and cool the ambient temps.

I'm not positive, but I'm guessing pipedream knows, that those portable air conditioners pull air from the room through the hot side of the unit and then exhaust - so if you're room smells so does your exhaust. But if the room smell is under control...

but still back to the window A/C unit which will be cheaper.

seems a better thing but then again you can't run it during winter w/o drawing attention - but you'll also draw suspicion dumping heat out of the window with a portable air conditioner.

Ideal is to have an apartment or house with central A/C forced hot air heat as you've already got a system for circulating air in your place.

So hmm... a 150 watt cabinet will easily disapate it's heat within a 10x10 room w/o issue and as long as there is some air exchange to other rooms via space under door, etc you should be good.

So bigger cabinets like 400's can easily overheat a room and you need to exchange air

If you can exchange the air effectively in the room with the rest of the place it becomes free heat.

But back to the key point which is that your cabinet cannot smell which is why I recommend getting a good carbon filter

Edit: I've known of growers who have good carbon filters and just recycle the heat into the rest of the house from multi 1000watters - saves them heat all winter - then in the summer they just switch to an exhaust outside - but after carbon filtration.

can i safely put 2 150watt hps lights in a dresser 30"wx18"dx34"h?? i have one in there now with a 52cfl for vegging seedlings, im not using the hps for vegging, this is my only grow space right now so i dont have a mother room or all that. but i was just curious if 300watts would be too much for this space when i start flowering!!
thanks!!

What would I be better off with for a full growth cycle? A 150w MH or a 150w HPS? I am not able to supplement the spectrum much at all. Thanks!

well that would be a ton of light but you could probably figure out a way to do it - you'll just need a strong exhaust fan

this thread is called the 150w HPS Club and Resource Guide... we all do just fine with just the 150 hps. Maybe a few daylight cfls for veg but otherwise the hps is fine from seed to bud.

sugar bear, do you think thats a little overboard or is that reasonable for a box that size, ill definitely be able to exhaust it well enough... i think i may just do a run with one and see how the yield is.

thanks alot!!

 

[sugabear_II]

hmmm, the st.

seems like a lot... but let's do the math....

30"x 18" = 540 square inches = 3.75 square feet...

a 150 would give you 40watts/square foot - slightly under the 50watt/sqft rule

2 150s would give you 80watts/sqft

but a 250 would give you 67watts/sqft

so maybe a 250 is the ideal lamp for your space. although 2 150s would work.

[The St.]

suga, dude, youre the man! i think i may use my 150 and maybe the 2 42 or 52 watt cfl's i have. im sure that would be plenty. thanks for the time!!! ill start a post up here soon on the micro grow forum, to show you what im working with!

thanks again!

Question

Question

I disassembled a security light (very easy, just like you said, thanks sug). My question is about mounting the socket in my cab. My cab. is only 33" tall. I'm wondering if I'll need to devise some method (like chains or something) of raising and lowering the light to maintain proper distance from the plants. I do have adjustable shelves anyway, even if I didn't set up the movable light thing. So I guess I answered my own question. I like talking to myself. What the hell. No one else listens anyway.

we listen... not that there's anything wrong with talking to yourself


With 33" height I would not bother rigging up the lamp to be move-able.

 

[Pipedream]

Having the ability to ove the light up and down can be a big help. I did it for a while, and also tried moving the shelf with the plants up and down. After alot of trial and error, I've settled on having both the shelf and the light permanently fixed in place. When there's a smaller plant in the box, I just put something under it to raise it up. This gives me the ability to have various size plants all in there at the same time, and keep the box structurally strong.

 

[qdavid]

Excellent guys, thanks. Another question, I think you can help. I want to read all the pages of this thread. But it's kind of a pain going to "first" then going 5 pages at a time until you get to the page you left off on. This is more an admin. question, I know. But is there an easier way to get to the page you left off on?


Great! I also meant to add this picture of my "Holiday desktop". You might recognize it. The photo is from this thread. I just put the word "peace" on it. Happy holidays>

[sugabear_II]

I agree with pipedream that you can always raise individual plants.

When scrogging as I did I found often times this was unnecesary.

Take a look at this profile picture - see how the bucket plus the screen puts the plant right up near the fixed light. I then trained the plant to grow into a stadium around the bulb (close to screen directly under the bulb - longer branches further away from the bulb)



thus allowing the plant to be close both on the side


and directly under the bulb


getting the most out of the space.

Sure - just bookmark the last page you read or the next one you want to start on. Then update your bookmark each time you come back.

As far as the portable airconditioners go, I might be wrong because the only experience I have with them are commercial units not ones made for the home. My job requires me to spend time at large construction sites where the units were used to cool the trailers. I know that very often when the folks inside were warming their lunches or just making fresh coffee, you could often smell it in the exhaust outside.

new 150watt hps cab!

new 150watt hps cab!

i just put a post up for my 150watt grow cab if anyone is interested!
its in the micro grow forum

any ideas for it would be great!

PEACE!

 

[igrowdadankest]

Pics are here.These are Hashberry If know one knew.





All are sepaerat plants the oldest is 4 or so weeks and the little ons are 2.They are going kinda slow but atleast there growing.They are getting bigger now though.

 

[iriebowl]

ok im thinking of getting a 150hps but my new cab design is 2' x 3' x 5' so will i need more light in there? i have 8 26w cfls im using currently for flowering so would that be enough extra light?

 

[VapingBuddha]

iriebowl, not sure how many lumens the cfls put out, but for the 150 I wouldn't want more than a 2 x 2 footprint. With 2 x 3 I'd divide the area up and make the other 1 x 2 into space for moms/veg/drying/storage etc.
