Whats up everybody? Recently I've been trying to soak in knowledge on how to make a grow fridge.
Now I have found some ideas hear an there.
Yet it seems every body does the same thing, they cut the power to the fridge and/or get rid of the the freon.


WHY!! Isn't that the point of growing in a fridge. I mean why not use it to its full potential.
I know you can't get fresh air, so aid Co2

Can anybody tell why these people or so wasteful?

what are you talking about I never sayed anything about Co2 coming from freon, Explain to me how you got that from what a typed?

I just asked why those who decide to grow in fridges like me want to cut the power to the fridge and/or drain freon from fridge. Cause I think you would want to keep the fridge in working condition to keep the grow enviroment cool exspecialy when you have a 400 hps or any other lights.

say you had the fridge cut from power in your house, it would be close if not over a 100 degrees on the inside, now add a couple of light or just one big one. You now made a shitty oven... lets cook a pizza

Because if you run a fridge in addition to lighting/etc., it will run ALL the time. Which will send your power bill through the roof.

ADEQUATE VENTILATION is much more important than boosting CO2 - if you have a sealed fridge with plants inside, they will get no air circulation and they will suffer as a result.

Also, a refrigerator is designed to keep temperatures just above freezing. Your plants will not do well at that temperature. And who knows what the temps will be with lights inside?

Ok worried about wasting power put the fridge on a timer so it cuts off an hour after the lights do. Refrigerators usually have climate controls, and I don't understand where you up came with the idea that a fridge keeps a temp just above freezing. For water freezing is 32 degrees F. Now I don't know the freezing temps for other things you may put in your fridge, but I do know that my fridge is at a temperature of 40 to 50 degrees F. With a 400hps light in there I going to guestimate the the temp would reach somewhere between 65 and 80. Which sounds perfect to me.

Im not trying to sound a like a know it all or an ass, cause I'm not, well I can be an ass. I am here to learn. For air circulation I would use a fan. The only reasons you need fresh air is for Co2 and cooling. Fridge with Co2 being pumped in, problem solved. You never heared of an inclosed grow room?

Would someone smater than me answer please, I know RIU is full of people smater than me. Teach me lesson I don't care you make a fool of me. I want to get the fridge off on the right foot.

That is why I personally, would consider this way to much work. You'll still need to do a lot of drilling and running wires. You will need out-ventillation, which means cutting into a refrigerator and not rupturing something in the area you're cutting through. And the compressor may not be built to run constantly, which it very well may need to do with HPS lighting. Sure, they have climate control systems, but how many fridges are built to have temps up into the mid 60s? Optimal temperature for marijuana is in the 70s.

No, you're not being an ass - you're being creative. I did lots of "creative" things during my first grow, and found they were way more labor, time, and money than I originally anticipated.

Remember, marijuana is a weed. It'll grow and thrive anywhere. The things growers do merely optimize what it does. Switching from Miracle Grow to FoxFarm will give you an increased harvest; it's worth the money spent and you're putting no more time into it. Modding a refrigerator could take you 20+ hours of physically modifying, running to the store, and dicking around with the setup. You'll get an increased harvest. Let's say you get an extra half ounce - is that worth all the money and time spent? I guess it's up to you.

You would have a lot better grow environment using the same space a fridge would take up by using a decent grow tent. You need the extra space from something larger for your venting and fans. It is sometimes harder than you think to maintain that optimal environment you are shooting for.

good point from the both of you. Its going to take some man hours to do this. Some creativity aswell. The reason Im going to do the fridge is one thing it looks a hell of let better than a tent sitting in the middle of a room. Not ass noticeable. Two its going to a be a lot cheaper than a tent. Those tent or very very expensive. Plus I don't know how its going to be until betty the fridge is built. Im guessitmating on the temps but I thing Im right about the light bringing the temps up. Moops thanks for your response, and sorry about the calling you a dumby. I was tick off about something that happen this morning, guess I had to get the anger out.

Still I don't know where The 5hit got Co2 from freon from what a said, maybe he was just fudgen with me.

sounds sweet id be interested in knowing how it works out. i heard when making beer the hops let off c02. maybe u can make some beer in the crisper drawer.

Beer making help weed making... Awesome, No I will be pumping it in. Does anybody recomend a brand for the solenoid?

sorry bro you better do sum more resurch in that mater. please explane yourself on how your to use the freon to grow with.. your not making any sence..

freon runs in the fridge to keep the fridge cool. Im pretty sure you knew that. Now why drain it when you could use it to keep the fridge running cool. so the plants could have a good enviroment. Now if you put the the fridge on timer so that it turns on an hour before the 400 watt light, and then turns off and hour after the lights do, in theory it should keep the plant in cool enviroment. Not too cold and never too hot.

ya i see where your comeing from, but me personaly i like my rooms on the warm side.. in the mid to hig 80's. with lots and lots and lots of freash air flow.

My 3 Ideas...


One.
I would put the fridge on a temp sensor and wire it to come on when you get a degree over temp and to shut up 3 degrees below. Now I would assume that your motor will be going on off all day long. Your electricity bill is gonna go up but your gonna have one stable grow room temp till your fridge burns up.

Two.
I would take the very bottom glass shelf and save it. I would then cut out the bottom of the freezer and use the glass to turn the freezer compartment a sort of cool-tube. Were your light could be in the freezer and your plants separated in the fridge by the glass. You could vent your light from the back with two 4 inch fans. This would not only gain you allot of room to grow because the light is higher up but you can use the stock shelf in the fridge to control "light height".
This method appeals to me because of the separate venting. One for heat from lights and one for fresh air. You could have your Co2 delivered and use less Co2 because your venting less. You could control temps below, in your growing area, with one exhaust fan at the top and pump Co2 into the bottom. You could also put oxygen hoses into your pots. Hydro would be pretty easy with this to.

Three.
Well I would just grow next to the fridge and keep people out of my house, use the unaltered fridge to chill my fat tires. This is my method of choice, but if I ever have to grow in stealth and I have a fridge I would use number Two.

This could be a very interesting project. Just be careful! It's too easy to rupture a freon line, which renders your fridge into no longer a fridge.
