I love the DWC, hence my name on here DDub, will be following.

Where do you get this idea from? It is completley not normal for this to be happening and is a sign of something wrong.

Ditch the aluminum foil, bad hot spots, flat white paint is better than that. Poly is good Mylar is best. I would not suggest watering everyday. Plants like to go through a wet and dry cycle. What kind of soil is that it looks like wood chips and probably doesn't drain well. You need...

I think we can blame this one on JIMI HENDRIX

Love the DIY aspect to your setup!!! You will want to spin that light 180 degrees though so that cord doesn't go across grow area and is on the same side of the exit for it. What kind of temp is the air that will be drawn into this room?

You can get a 25' x 10' roll of Panda Film on Ebay with free shipping for 33.95, which is a good price, the store name on Ebay is sunsethydro. I assure you this is quality stuff and will work perfect for this application.

Do you not have a local Hydro shop? If not why are you opposed to purchasing it off the net? It in itself does not imply that you are doing anything illegal.

Roughly 20Watt/Sq. Ft. will be fine for Moms.

1/2" Plywood, 2" x 2" boards, 1 inch wood screws and some Black and White Poly. Construct a rectangle out of Plywood. Do this by Cutting Four Identical sides to the rectangle, you must determine the size of these sides depending on height of the plants and how many plants you wish to keep...

That is quite impressive production. Have you ever thought of converting this into a scrogg grow due to your limited vertical space? I think you could increase your yield this way. Either way its a great setup keep up the good work.

Yes that is constant, turning off your Exhaust for even a half hour would result in a HUGE flux in Temp. and a terrible stress to the ladies....

That is a very good question that I don't know the answer to. **Also I must mention this does not refer to CFL lighting** Only for MH/HPS lighting.

Yes a fan has to be pushing air through or pulling air through. Just putting it in there with no fan connected to it will do nothing. If you have no intake or exhaust and are just looking to control odor look into a Ozone Generator. But you will need to deliver fresh air and remove old air...

Ok so if Temp in room is 70 right now the calculation I made in the post above is exactly what you need to exhaust this grow area, not the light. The calcualtion I made above would keep your temp in the Homebox at about 75 Farenheit now and 80 Farenheit in summer, 80 is too warm. You need at...

Yes you are doing this wrong. First of all this calculation has nothing to do with the size of the room. Answer me this and I will tell you what size fan you need. What is the temperature (in Farenheit) of the room that your Homebox is in.

This is how you can calculate the amount of ventilation you need. If you wanted to keep you grow room temperature from getting any more than 5° warmer than the intake air temperature, and you were using 400 watts of power, you’d make the calculation below. CFM= 3.2 x Wattage/ Difference in...

You will be needing to move more air about 250+ CFM without an air cooled hood. How are you intaking air that is important as well. You will surley want to have a small oscilating fan inside there to stir up the air as well. A cheap fix for you without having to buy an inline fan is to use a...

The light is perfectly fine to use in that box assuming you can control Temp still. An air cooled reflector would be ideal but it can be done without it. Do you have a passive intake or are you using a seperate fan for exhaust and intake?

You already know....

AN is a complex system, far more than alot of other Ferts. I would suggest spending the loot on some AN A & B, you already got everything else CHEAP!!. I wouldn't switch nutes in the middle of a grow but have known others to do it, very experienced others. Use the AN in hydro. Great steal...
