yeah, you're looking at appr. 672 grams. If it gets much taller, I might expect it to do that in the last 30 days of flowering, at a four foot plant, can you count the internodes and post the number? I'm trying to break down an average internode/yield expectancy ratio among strains. It ought to...

Thanks for the info, mockingbird. Wires are all hooked up right. My 150 MH is wired the same and works great. I'll try those scotch locks, I can get them at Lowe's or Home Depot?

I've got my superior females vegging under fluorescent right now. They are 6 weeks old. It's time to introduce my 400 watt metal halide, but it isn't working. I've successfully spliced the wires from the ballast onto the female end of an extension cord with smaller wattages, and end up with...

Never overtax the capacity of your lowest gauge equipment. In this case, 40 watts.

Ok, now I feel stupid for reposting. Thanks jcommerce, they came up with a brilliant filter idea and it works.

Check out the thread Cheap Carbon Filter Setup - All from Petstore!! I got my ductwork at Lowe's, $8 aND BONDED FILTER PADS FOR $4. i GOT THE ACTIVATED CARBON AND FILTER FIBER AT petco FOR $4 activated carbon, $3.50 filter fiber. Excellent filter works for up to two months, $21 total.

Or, if you're broke, like me, spray seltzer water on the leaves directly, making sure not to touch the hot lamp surface. The CO2 is released and plants will love it! do this twice daily, but modify your watering system as transpiration is decreased substantially. Don't do it during flowering...

Thanks for the excellent article, growbot, but it left something out. CO2 does comprise 0.03% (300 ppm) of our atmosphere, but maximum CO2 absorption by cannabis is 0.2%, or roughly six and a half times current atmospheric limitations. All CO2 sources have a by-product rating. One pound of...

It depends largely on your ventilation. Are you maintaining between 65 and 75 degrees? If so, a 400 watt metal halide can be placed up to one foot away without risking damage to the plants. If the air is not vigorously circulated, the heat is exponentially increased, anything above 80 degrees...

Check out Marijuana Horticulture: Medical Grower's Bible by Jorge Cervantes. It's $15 on amazon or $20 at Borders. It's has a complete chapter on aeroponics and some delicious pics! I would say introduce the HPS light now if all you have is fluorescents. CFL's do an amazing job during veg, but...

I use a 400 watt and 150 watt MH for veg and flowering. It works great, but a buddy of mine has seen better results with a 400 watt metal hallide for veg and 400 watt hps for flowering, since high pressure sodium tends to be stronger in the red spectrum. I ALWAYS use cfl's for seedlings. They...

Tested the products for this filter, works like a champ! Grow system is in a closet, so I used a collapsible ventilation duct with an 8-inch industrial fan as the exhaust. With 12 pre-mature plants, I expect full odor and dust control of up to four superior flowering females. Kinda have to go...

What you need is a wick system. Works on soil or dense soil less mediums. Run a nylon cord 1/2 inch thick horizontally through your pot into the middle of your medium. The end of the nylon cord should dip into a reservoir directly beneath the raised pot. Osmosis will draw the water into the pot...

There's no chance of fire, the wattage of the bulb does not exceed capacity of the ballast. Also, this exact setup worked in it's previous location. I'll try the 400 watt bulb, but still wondering why it worked in it's old location, but not the new one. I assumed that maybe it was an incorrect...

The amount of water utilized and the nutriend solution formulation are factors the both go into determining flow rate. For example, a fairly concentrated nutrient solution can be applied, sufficient to meet the crop requirements for a specified time period, and then water applied as needed until...

I used one of those bathroom fans, but mine was industrial, I think it ran at 4,000 RPM, but that's just a guess. I can tell you I got my hand cought in it and it took off a chunk of my knuckle. In any case, it was too strong for my growbox, which I converted from my dishwasher. I'd suggest any...

I have a 400 watt ballast and fixture, with a 250 bulb. It has a magnetic ballast, and was direct wired before. In it's previous location this combo worked just fine, but when I brought it home I spliced the wires from the ballast onto the female end of an extension cord. This method of...

Oh yeah, I almost forgot. I have a myspace and blogger for people who want to talk one-on-one with me about pot. Check it out, MySpace.com - Kief - 70 - Male - OKLAHOMA CITY, Oklahoma - www.myspace.com/drkiefreefer and Marijuana- Re:Legalize

Hey, been smoking for four years, growing for six months. I'm new to the site too. I just had to sell my whole crop (12 plants at one month old, non-sexed) to another grower because housing issues. I really need a place to grow! What is piccasso without his canvas?

I'm a student in college right now, but I would major in cannabis if I could. What I have done is set up a myspace and blogsite for potheads, but it focuses mainly on trying to get mainstream America in the know. Check it out, cause I need advice on how to make it fancier. MySpace.com -...
