"As I understand it, I need to mix the different wavelengths to activate all the different pigments. But how many of each is a puzzle to me. Also been reading some articles that 24% green light is a good thing boosting photosynthesis a whole lot. I dont know why." This is a logical error...

Bud production with just two low wattage CFL will be, well, pathetic. But, since you are trying to go stealth with a PC case grow then CFL are your only option. I would get the daylight spectrum CFLs and use tin foil on the walls of your PC case. If CFL is your only option then do it...

The answer is yes! You can use an HPS for veg. The reason why so many people mention that they have 4, 6 or 10 CFLs in their garden is because it takes that many CFLs to replicate the intensity of light produced by a single high pressure sodium or metal halide HID fixture. an example: a 150...

SOG is simple: you flower the plants when they are about 12 inches tall. Cut off the lower most branches as they tend to get the longest first. you can also top your 12 inch ladies and create more than one cola... Many small plants flowering at once Creates the "sea of green." Some would say...

I'm using 120mm fans which measure about 4.7 inches across, so I guess i need 5 inch PVC elbows... I'm only concerned with the method of attaching the elbow to the fan. Although I can certainly rig this on my own, I really like the post where it was explained and pics were shown.

I found a thread here where someone used a PVC elbow with a fan attached to it to light proof the fan port on their grow box. I have not been able to relocate that post. Can someone please give me link to this post or explain how this is done? IF, you have done the same thing and you have...

dude you don't wanna have half a window AC unit hanging out your sliding glass door. this sounds like a good way to attract attention. Get a portable ac unit, the type with wheels on the bottom. they usually come with ducting. you just attach the ducting to the hot air out, and run the...

maybe he's not interested in saving and wants it now.

An AC to DC power converter from radioshack with a 100 watt rating or better will serve you well. Fan wires may need to be cut and wired onto the leads of whatever PSU you buy. PC fans come in all shapes and sizes. Get the one which fits best for your grow area. They also come in different...

He can't afford anything bigger, remember?

Was the grow light off when you took that pic?

Man, that plant is nearing harvest time. No more cutting on it bro. Just keep the PH tight and wait for this too clear up. That plants has nice buds going!

Do this while waiting for your new bulb to show. Go to home depot or lowes and buy a second bulb. Start using that one immediately and when you replacement shows just stash it away as a backup. this way u won't have to worry about acquiring a new bulb fast, because you already have a...

You need to keep the soil moist also. Take a very small cup of water and poor in a drizzle around the base of the plant. Just make a circle around the plant with the water, making sure not to hit the plant. Check on it the next day. if the soil is dry again then add one more small cup full...

well, this is the first problem that comes to my mind: garages are hot and hard to cool. If you are going to put the box out there I would definitely add fans to it. I would go for 120mm PC fans on a 12 volt power supply. For a box that large, I'd say at least 8 fans. 4 pumping air in and 4...

AHA, wonderful! you are considering buying my light. I have the Sun Systems 150 watt HPS also. I love this little light, I must say. The compact size of this unit is perfect for my grow cabinet in my sig. I simply mounted the light in the top of my box. Its lite weight and perfect for a...

One more thing. A gentle breeze blowing over the top of the plants makes the stem stronger. It is a proven fact. So you might want to add an oscillating fan to your set up. You don't want a hurricane going on, just a gentle breeze that makes the little plants shake slightly every time it...

Ok, just a bit of advise for you. the bark chips in the top of the pot are not necessary. they are doing nothing for you at this point. In fact if you water and some water bounces off one of those bark chips and hits your plant, it could fold it over and ruin it. They are way too young to be...

you better get rid of that hermie before he spooges all over your other plants!

now that I think of it. You might be able to get away with a 4x2 tray and 3 rows of 4 plants with ebb and flow. I had a 4x2 tray, the type one uses for ebb and flow and I had 6 large plants in it. I guess, in order to have 12 plants they would have to be roughly half the size of the plants I...
