Damn, thats a big light for that size room. 6" air cooled w/ vortex fan. Ducting drawing air through the out side with the intake flange of the hood not connected to anything - will draw the air right out of the room and across the light. You will need to vent to a separate location. Venting in...

If you put them near the HID, no they will do nothing. More watts does not equal more available lumens. At any location, a plant will see the brightest available light and nothing more. However, if you add them to shaded areas around the perimeter, they will then be the brightest light at...

I agree with this. The 2 bulb is going to spread the light into areas that the plant won't be using. A tighter (shorter 2' or 4') fixture with more bulbs will give you better intensity. Try to keep the light the same size/shape as the area that your canopy will cover. For 2 plants, I'd consider...

RO offers the ability for the grower to control the waters content almost 100%. I like control...

First off: How far do you trust him? Would he dime you? Will he tell anybody? Will he mention your name talking to people about the grow? If he will, your probably fucked. Does he rent? - Its probably a bad idea. If you do trust him, you should stick to your guns and it should be 50/50 if he...

I think if you order small quantity you are less likely to get jacked. They don't want hundreds or thousands of people bad mouthing them. If they can make 500$-1000$ and have 1 person bad mouth them is more tempting.

I have heard that the top 1/3 of the roots absorb mostly nutes and the bottom 2/3 absorb mostly water. Can any one confirm?

Depends on what you want. A 1000w will penetrate into a deeper, denser canopy. You could have a larger yield/plant. The spacing is really too close for really bushy plants, so you'll need to keep them kind of small if they are bushy indica strain, start 12/12 pretty early. Thats why I...

I'd say you'd be fine with a sativa strain that doesn't bush out too much. You should get a 1000w light or lots of t5 side lighting to get light to the lower buds, though.

I'd say it would be great, especially with an aircooled hood. Get a digital ballast. They don't buzz.

Happy to help

I guess I meant that it doesn't have the circular dripper thing that disperses the solution throughout the medium (though you can buy those online). Also note that the water line is way below the medium in the waterfarm. From my understanding, you were going to keep it up in the root zone...

The problem is that propane only produces CO2 when burned cleanly. BBQ grills are not known for a "clean burn". If you are seeing more than just the tips of the flame are yellow (not blue), or any green, you are producing poisonous carbon monoxide or other dangerous emissions. The production...

t5ho's generally produce more lumens per watt than your normal store-bought cfls. They also produce less heat and a more even distribution. They are also much more expensive. As it is with much of growing, if you can afford the upfront cost, you'll likely save money or see better results down...

That, my friendisa modular waterfarm without the dripper. Would you consider a DWC to be more efficient than the dripper/dwc hybrid?

I was just looking at those. Do they not have a separate switch for the lights? Id ask the seller...

You will also need an 02 sensor and a co detector. You could very well kill yourself from carbon monoxide poisoning or asphyxiation.

Been thinking about all this... The seperate res does pretty much cover all of it. Most commercial systems designed similarly use a drip system. Yours would be a lot like a waterfarm without the dripper. A couple of notes if you decide to push on: An occasional good flush w/ florakleen should...

Sorry, you'd linked to it in the first post, so I figured it was cool. Read this No, I don't believe it to be detrimental. I initially mis-read my meter and hit them with 7500 ppm nutes, which burned the shit out of them, so they look like shit now. The plants are thriving, though.

Propane only produces co2 when burned CLEANLY. If it does not have the right o2 to propane ratio, it will produce deadly CO gas. Co2 generators are precision pieces of equipment that are designed to control the o2 ratio and control the burn. They also have safety sensors integrated that make...
