NeL's 5 strain 1200 watt Grow

you have a backhoe? i'm jealous.

Well no. Just my machine for plowing.

So I'm in the middle of setting up some decent size rooms for a few close friends. Heat is always an issue in the summer an who the hell wants to spend money to buy and run an AC all the time. I was comming up with a way to use a car radiator, fan, and a mini fridge to make my own cooler. What I really wanted to try is those inline radiators from Hydro-Innovations. Luckily I stumbled apon an RIU member who made a really nice one DIY style for short money.





Here's the DIY link , Props to FatFarmer34https://www.rollitup.org/do-yourself/234834-diy-icebox.html.

And a few pics





And here is the video from H.I.

Did I mention I was a "CAT" guy, lol. This is from last season front of the house. I'm trying to imagine it's warm outside.

really interested in this water cooling setup cuz I deal with high temps during summer too and would be nice if I could cool the room at the same time. still a bit confused on it all tho after seeing all the different ways of doing it in that thread.

so is the fan in this picture drawing air through the venting or pushing air through it?

and what were you planning on using as your chiller? or were you going to make one yourself?

 

[northeastern lights]

The "ice box" is on the exhaust side. It acts as an AC if you can keep the water cold enough. Hydro-Innovations had their temps comming out at 58.



I'm undescided. I might use my mini fridge with a copper coil in a 3 gallon bucket in water. From there it will go to the to the resevour as in the pic. I'll use the mini fridge as a chiller.

Here's a quick write up from their website:



Features:

Engineered for maximum efficiency
Allows you to keep a sealed room which keeps your CO2 in and pests and pathogens out
Water approximately 10 degrees cooler than the room temp will eliminate the bulb heat from a 1000 watt lamp
Water approximately 20 degrees cooler than the room temp will reduce or even eliminate the need for a/c
Can be connected directly to the reflector or can be wall mounted with optional wall mount kit Recommendations / Equipment Needed:
For proper function the Ice Box must be installed on the exiting air duct flange, not the incoming air!
Gardens with 50% humidity or higher may require dehumidification to avoid condensation of the equipment and water lines. This can be solved by using a dehumidifier and there are water-cooled units available
Air-cooled reflector and inline fan with approximately 250 CFM for maximum efficiency

Approximately 250 cfm of airflow is needed to properly cool the fixture.
Pump sized at 300-500 GPH with 8-10 feet of lift/head pressure
Chiller size per 1000 watts: 1/4HP Minimum, 1/3HP Optimal
With properly sized chiller, reservoir size of 25 gallons is sufficient for almost any set up
For optimal performance use one IceBox per reflector
Designed to use with 1/2" tubing

thanks for posting that diagram. that really helps seeing the full breakdown of the whole system.

are you worried about condensation build up in your hood tho? and how much you think you can build this all for?

The oil cooler is 48 dollars, it's bigger than the one from Hydro Innov.So 48+13.95 for the duct work. Some line, a few fittings. I'm thinking under 100. I already have most of what I need.




It would be so nice if I could cool the room without AC. I will buy a chiller eventually. They are fucking expensive though. The 1/10 Hp is about 379.00

yea I was just checking out chillers. soo damn expensive.

I think I'm just gonna keep it simple and go with a small a/c. I love the idea but gets a bit complicated for my liking. I found some small 5000 btu a/c's that could probably cool my room too much for under $150.

definitely want to know how your attempt at it goes tho

 

[northeastern lights]

I'll keep you posted. I bought a 6000 btu Portable AC off craigs list but It didn't cut it for me. i sold it to my cousin

how does that cool the light if it is after it? why not put it before the bulb? i draw in 30 degree air over my hot bulbs.

it's supposed to cool down the room then in turn cooling down the hood and the bulb.

I thought the fan would be drawing air in tho and not exhausting it like in that picture.. seems like it'd be more effective that way

i'd turn that fan around.
but it could have a "theory". i haven't looked that deep into it.

I thought the same thing but if you watch the video the guy has 3 1000's and the air comming out is 58 degrees That's cooler than an AC. This way I can use Co2 and have a sealed grow. Maybe just have an exhaust for high RH, maybe just a dehumidier for the winter. Many options.



Wife and 3 kids are flying to Peru for the next 2 months. Looks like I'll be setting up the Hydro in the kids room, hehe.





I've been framing in the city, and looks as if I got a few weeks so I might buy a chiller but I'm definatley making the heat exchange.

The one in my hand is the Crooked Prairie, by far the best structure out of all the strains. THis thing is STACKED



Going to feed them tonight.

It cools the air comming out which in turn cools the room. If you have a few in a row they are on both sides. Watch the video and tell me what you think.

I watched the video when you posted it but I watched it before I read the thread you posted so I didnt really understand it all when I was watching the video but fully understand it now and like the idea. but if I was going this route, I would definitely have a drain line for the condensation that'll build but I know you got all that on lock already

and the internodal spacing on that crook'd prairie is almost nonexistent! can't wait to see what they'll do indoors

well of course the air coming OUT is cold. it is coming from a chiller and it's not even passing over the lights.
you are cooling the exhaust not the lights. why not cool the lights?


your seedlings look beautiful.

Cause the air comes out of the light and back into the room. I thought the same thing. Tomorrow I'm ordering the radiator and we'll find out. I can't wait to try this. I'll try on the exhaust first and then the intake.






Out of every update or new thing I've added to my grows this seems like the messiah of upgrades. Usually when it's to good to be true, it is. We shall find out.

 

[fdd2blk]

i thought they idea was to cool the bulb so you could get it closer to the plants. seems like you could do both.

i'm just confused, sorry. :-\
