Yeah I'm hoping ur right. I got real excited when I saw what smelly got off his KK alone. There has to be a pound and a half in there when its done. We'll know in a few weeks! u must be getting excited too. Ur ladies are looking great and filling out nicely!

I've always grown with soil or bubbleponics. I like soil cause it's so low maintenace and forgiving if you make some mistakes. I don't want my setup consuming lots of my time and soil is just easy. I read some stuff about the jets and sprayers getting clogged up and being problematic and that turned me off from aero but I have no experience with it to actually draw an educated opinion.

heres some info i found on Co2 for ya. and thanks man, i am!!
Carbon Dioxide (CO2): Marijuana plants consume carbon dioxide (and expel oxygen) in the daytime hours. During the dark period at night they consume oxygen (and expel carbon dioxide).
When the light is on in a grow room, plants will consume CO2. In a room with little or no replacement carbon dioxide, plants can consume all the available carbon dioxide in an hour or less.
When CO2 levels fall, plant growth slows. Letting in air through a window, door, or other means (and keeping it circulating around the leaves with a fan) will be necessary.
CO2 is measured in parts per million (ppm). The amount of CO2 present in outdoor air will generally range from 350-430 ppm. Away from cities, where the air is cleaner, carbon dioxide will probably be concentrated in lower levels than in the city.
Plants can do well if the amount of CO2 supplied to them remains in the range of outdoor air (350-430 ppm). At levels below 200 ppm, plant growth slows down because the amount of carbon dioxide available is too low.
Increasing the amount of CO2 available to levels over 600 ppm will increase the growth rate of the marijuana plant. Although this does not mean a more potent crop, it will produce a larger harvest in less time than a crop raised with CO2 levels are not in the optimal range.
When the CO2 level goes over 2000 ppm plant growth will slow down because the concentration of CO2 is too high. In order to maximize yield and minimize the length of time till harvest, some growers increase the amount of CO2 to the grow area so the plants have a steady concentration of about 600-1500 ppm when the light is on.
The optimal amount of CO2 will depend on the amount of light available and the temperature of the air that surrounds the leaves. As the amount of light and temperature increase, the plant is able to process more CO2. This results in a quicker growth rate.
Here are some CO2 levels and how they affect plant growth.
Below 200 ppm (Plant Growth Slows)
350-430 ppm (Outdoor Air)
600-1500 ppm (Optimal For Marijuana)
Above 2000 ppm (Toxic For Marijuana)
If possible, maintaining carbon dioxide levels at 600 ppm or higher when the light is on will be best for marijuana plants. Levels between 1500-2000 ppm will not harm plants but even in strong direct sunlight amounts higher than 1500 ppm will probably not be consumed. As levels reach 2000 ppm they start to have a negative effect.
If you have to vent the air out of a grow room with an exhaust system that removes air from a grow room, most (or all) of the CO2 will be removed from the grow area before the plants can use it.
An air cooled lighting system that takes in and exhausts the air from places other than the grow room is suggested when CO2 is being added. Alternatively, a grower could construct an exhaust system that only turns on when carbon dioxide is not being added.
Adding carbon dioxide to a grow room is not something for the beginner to experiment with unless you have a cheap and easily obtainable supply with a means of measuring it.

I've also had the big digi lamp turned up to the super lumens setting 4 the last 2 weeks which is suposed to be an output of 1100 watts plus the other 300 watts on the sides would make a total of 1400 watts HPS now. Boy is it fuckin bright in there! It will literally hurt ur eyes to look at it but no worries cause my temp is around 79-80F now. Cool sailling and I could cool that down more if i wanted but I don't see a need for it. They seem happy and are producing well.

Damnnn Mass...this is my first look at your thread and its another amazing grow! I wish I has room for HID but at the moment I dont. I get more and more blown away at folks like you each day out there kicking ass and taking names with their own grows. Im adding another one that has inspired me to my list. Thanks

Thanx so much for the encouraging words! +rep for stopping by! I'm glad to see someone else checking out my thread! I learned everything I know about growing from this site (I've read a few books too) and I look forward to and somewhat depend on feedback from other growers like urself to let me know if I'm on track or if I have any issues I need to tweak to make things better. This is what I consider my 4th grow. The first 3 were done under first 150watts hps then 2 and 3 were under 300 watts hps, all bagseed. I wanted to learn b4 investing too much money. This is my first grow using purchased seeds from a seedbank. I also bought a Lumatek dimmable 1000watt digi hps/mh. It also has the super lumens setting (thats where ive had it for the past 2 weeks) which I'm told is an output of 1100 watts which would put me at 1400 total watts of hps now. My bulb is also enhanced in the blue spectrum. I have a 150watt hps hanging sideways on both sides of the grow as well. I got light everywhere! I can't wait to see how this turns out! anyway, thanx 4 stopping by and I hope u will check out my girls from time to time and give me ur thoughts!

my whole set up runs off timers and is hydroponic with a 30 gal rez and i go once a week but it can go up to 2 weeks if need be without being changed. also my brother will help me out if I need him to. its only about 45 mins from me i just didnt want to live where i was doing it cuz if the laws here. Which are asinine and someone should be punished for lying to the American people for so long!
I am also looking at an automated system that does all that (Mixing, watering, PH) everything all by its self or you can control it from a computer program .. really cool !!

Sweet buds. It's kinda cool to not look at them for a while. Sometimes it's hard to appreciate how much they grow if you look at them everyday.
