MY semi-DIY STEALTH Cabinet! Version 2.0!

[Danielsgb]

Nice and clean set up. Couple ?'s. How far is the screen from the Cool Tube? How are the temps? An A/C seems overkill IMO. More air flow can do wonders. What nutes are you using? Was it an 4-8-1? Seems low on K to me.

The cab looks real nice. Just curious...how much did everything cost you? I'm also wondering what the purpose of the false floor is.

 

[oOBe RyeOo]

looks real good but why do you need a portable AC? i like the false floor, and it should help keep rez temps low. but it also gives you a chance to play with placement, and size of intake holes. if you are having temperature issues you may need more intake, or better placement of the intake holes in conjunction with the exhaust holes. and remember not to place the sensor of your thermometer directly in the light, because that is giving you the "radiant" temperature, not the air temp. the air temp is generally much lower than the radiant heat. also, do you have intake fans, or are they just passive?

When I have the cab running in my closet the temps are generally in the 90's. It's really hard to make any mods to the actual cabinet itself because I built the wooden box inside of it. I'll have to pic up a regular therm. to put on the wall to see what the temp really are. I've wondered whether the thermometer I have now worked or not.

The screen is 20in. from the cool tube, and the temps range from 85-99+.

For nutes I'm using Flora Nova Grow/Bloom. I'm not sure on the numbers right now. I'll find out later tonight.

I'm not exactly sure how much, but if I had to ball park it I would say $1,200. The most expensive thing was my fan, and it was $240.

The purpose of the false floor is to help keep rez temps down and spread air around better.

 

[oOBe RyeOo]

OK the max temp for the cab is 92.6*F

 

[littlegrower2004]

what fan are you using to cool your light? i had high temps in my closet and had to get a AC just to cool it. plus a 440 CFM HO Can Fan.

Hey oOBe RyeOo,

Finally ran across your journal through stelthy's. The false floor idea looks great. That's how my cab is setup except my false floor is made when all the foam tops of my water tanks are side by side. I draw passive air in from the bottom like you do. I make sure that the water tanks are pushed towards the outside of the cab making a 1" slot in the middle which allow air from under to draw up through the center before being drawn out from the top corners. It looks like your air intake is from the air in the closet next to the cab. Just use the AC unit to cool this space next to the cab to 68*. This will become your "ambient" temp and since it's cooled to 68* will be pulled across your water tanks down below before drawing up into the plant space keeping your water temps in check. I used rigid foam and pvc tubing to build the same sort of space to cool and draw into my cab. You can even use foam and some rigid tape to create a plenum box inside the closet which you keep at 68* which will use less electricity rather than cooling the entire closet.

You'll also have to deal with getting rid of the hot air from the heat exchanger which will get pretty warm. Enough so that it will "pollute" the cool air you put in. Get that hot air out of there using insulated ducting!

Check the last few pages of my Variety Grow journal to see the concept in action.

BTW, I'm sub'ed too. Your cab looks great!!

it is a sweet cab sucks your having temps issues though

See, I was thinking about doing something like that. I was just wondering if I could manage it without the a/c... but I'll probably go ahead and get the a/c.

My fan is an 8in 520cfm inline.

Thanks. I'll over come it though.

Thanks. I'll over come it though.

I remember someone named Gumball nudging me to buy my AC unit just so it would give me "piece of mind". Well now my piece of mind is having continuous 68* ambient temps for my cabs to pull from. At first it's a bit painful to hear the AC cycle on, knowing that the old electric meter is spinning a bit faster, but when you see a continuous parade of pure white roots coming out of your netpots, you stop listening!

For piece of mind, buy the AC unit (if you can afford it). Never having to use it is a problem we would all love to have, but when you need it and have it, just think how stoked you will be when your plants are happy while running in the middle of a heat wave!!

Another thing to remember is RH. Adding humidity will drop your temperature as long as the RH is below 50% to start with. I keep 4 sopping wet rolled up bath towels in each cab. This give me at least a 10% RH bump even with exhaust fans running on full! This RH bump usually leads to a 3* - 5* drop in cab temps. For me, current outside RH is 28%. With the four towels, my cab get's up to 43% RH @ 79*. As the towels dry out, humidity goes down and temps get up to 86* in the cab.

Hi dude, Just checked out your pics and decided to have a look through your thread, I can see 'influences' in your setup and am pleased as well as happy to see things going to plan...


NOTE :

* A few things I'd do to improve your air flow.. to cool/control the grow-cabs temps, would be to cut out the intake hole completley where you have drilled holes (in the side) this will enable more air to be channelled in with less restriction, as well as lessening the sound of the air movement.

* Some kind of filter in your intake is always good because 'The smell' can excape due to the turning on/off of your in-line fan and negative pressures back drafting.. I used an Odor Soc as it seems to breath exceptionally well. Remember the bigger/longer the sock the more air is able to be drawn in to potentially cool your lamp.

* Another thing I would do is to increase the size of your grow shelf vents and install 2 CPU fans wired together elevating your in-taken air, I'd wire them to a transformer plug so whilst the plants are small you can have the CPU fans running on low and as the plants mature ~ So you can turn up the speed of the CPU's to keep the temps cool especially near the tops of your cola's apart from that you should be fine...

What wattage lamps are you using? I mean providing you are using less than 600w you should be fine.

I have enjoyed reading through your thread, and wish you good luck man! You have some great seed's there, And there's alot of potential with your setup and their outcome

Hope this has helped man.... ps REP! for your efforts so far - STELTHY

You're totally right about this. I actually cut that stuff off last week, and it did indeed quiet it down with more air being sucked in.

* Some kind of filter in your intake is always good because 'The smell' can excape due to the turning on/off of your in-line fan and negative pressures back drafting.. I used an Odor Soc as it seems to breath exceptionally well. Remember the bigger/longer the sock the more air is able to be drawn in to potentially cool your lamp.

My fan never turns off. Do you still think the filter is necessary?

I figured I would just put two or three more holes about the same size.

Thanks for the advice.

 

[littlegrower2004]

sounds like you have a good fan so if that isnt working A/C might be a must like it was for me. like JS said, it sucks knowing the meter is spinning but your plants need the cooler temps and sounds like an A/C is going to be your final option. hope you figure it out.

I'm not talking about the plants dieing... I'm talking about the po po finding out about it.

Why does this announcement NOT surprise me? I knew all along .....

Don't want to be guy on the news, "And he was dumb enough to put it on the internet".

You are on the internet.... your plans, your details, your 'stealth'....

So I guess everyone else here that does share grows and pics is dumb? Ever hear of a proxy?

I'm not surprised by your 'announcement'.... I've been challenging you for months to grow something and you still haven't. Get off the fence already...

Serapis let me help you. You seem to be worrying about something you have no control over. When you worry you create stress in your body which floods your body with adrenaline through the "fight or flight" mechanism. But when you don't end up fighting or fleeing, the constant flooding of adrenaline starts to cause chemical changes in the brain which if left unchecked could lead to your mind and body going into a depressive state.

My recommendation, leave this thread, forever. Since you don't have to worry anymore about this thread, your quality of life should instantly improve.

and good health brother!

Hey man whats going on you still in the build stage? I got a problem paying retail for Dank so I grow, maybe you don't. Just tell the litte hater to piss off!!! I have never heard of anyone ever getting popped from posting. Doesn't mean its not going on, just bigger fish to fry. Commercial ops are the targets not indoor tiny little 3 to four plant grows...From what i can see you only gonna run one plant at a time anyway..That little cab isn't going to grow so much that you cant handle it...CUT SOME BIG ASS PASSIVE INTAKE HOLES!! keep doing this until the thing cools down...You can get to about 6 degrees above the ambient room temp if you move enough air....Whats the ambient room temps now?

Bravo!!

Serapis, I have seen you in many threads disrespecting the OP, and the discussions in those threads. Maybe its time for an RIU vacation. You create a negative vibe that your knowledge of growing will never compensate for.

Good luck friend, life's lonely when your alone...
