As for the best cheapest what I want is the best material for the job with out going overboard. What you think?
Again thanks for input
thanks for the input simone. I have an Elicent 4" 152 cfm inline fan but I dont think that will be enough for the filter and to cool the 400 watt cool tube. I figure the vortex will be more then enough so I can turn it down a little with a speed controller and if i have to buy new filter so be it. As for the best cheapest what I want is the best material for the job with out going overboard. What you think?
Hey Simon
Your right about the fan noise but I think I can live with it. I'm going to try the Elicent and then go bigger if i have to. As far as the cool tube I thought one of the main advantages was being able to get that light close to the plants giving me more space. I want the temps with in 5 degrees of house temp. with out a cool tube you have to keep the light a foot away from the plants right? I was going to go with 250 watt but 400 is about same price I was hoping the extra watts would make up for the poor reflector.
I think I'll go with the marine grade if I can get at home dep. How thick?
Thanks for all the help
sorry so many questions
I can only go 55" tall because its in closet. So you think I can keep a 400 watt that cool in closet with out a cool tube?
I want about 200 grams per harvest. How much light will I need?
Here is a picture of the control room of my cabinet.
Top Left is my srcubber and the gage that reads the static pressure across the fan, This lets me know how hard my fan is working and if my cabinet is working under a negative pressure or not.
Top right is my water reservoir with a sight glass that tells me the water level in the reservoir.
Inside the cabinet The top left gage is the read out display for the exhaust sensor (its a indoor outdoor thermometer with a remote outdoor sensor) and I have the sensor placed in the air space below the carbon bed.
The gage right below the exhaust gage is for the air intake sensor which I place in the intake plenum.
With those two gages I get the temperature difference between the incoming air and exhaust air. (more on this later)
Moving right the next device is the speed controller for the fan.
The next device id the light timer.
The next device with the yellow plug is the Kill A Watt device. I have my whole cabinet running through this device. The Kill A Watt give me the total watts, amp, voltage I'm using. The lenght of time in hours I have been running the cabinet for that grow and the total cost of electricity for the grow.
Now by using the temperature difference between the incoming air and exhaust air and the total watt I can calculate the fans CFM.
CFM = total watts * 3.16 / (exhaust temp. - incoming air temp.)
Total watts = 566
exhaust temp. = 97
incoming air temp. = 72
CFM = 566 * 3.16 / (97-72)
CFM = 566 * 3.16 / 25
CFM = 1789 / 25
CFM = 72
So my cabinet is running with 72 CFM at 0.90 in of water (static Pressure) and Keeping the inside of the cabinet at 10 degrees above room temp.
So, I thought I'd post a few pictures of the SLH buds on day 49 of flowering:
Yes, there is a lot of empty space in that scrog, but this was the freebie seed that I just wanted to hurry and flower.
