Hey Princess, Thanks for pointing out the potential probs with H202. Did'nt know it could be harmful. I guess its good that I have not used it so far. :grin: I got the 4000K bulb together with my switchable ballast www.plantlightinghydroponics.com. (See link for specs)...

bump - anyone?

I decided to go with a known brand Agrosun which was twice as expensive as the no name brand I found on Ebay. So I paid $59 for the 400W 6500K 36000 lumens MH bulb. Peace

Wow after Installing the 6500K light I could see the big growth difference! Thanks all for the suggestions!

Hey All! So, I'm on my first grow. I have done a lot of reading so I can hopefully get a nice crop on my first grow. However I've seen a lot of deviations in what is the ideal growth condition some times I wonder if it is a matter of opinion. I'm wondering what your 2cents are on my grow...

Yeap, they are tunring greener again after two days. So what does this mean? Is it good or bad? I have two theories: A. Good? Lighter green is desired. The number of clorophyll molecules made are a waste of energy therfore better to have the plants more pale which may be interpreted to be a...

Not so far. Maybe it takes a few days.

Thanks for the advice! I switched two plants last night and the leaves of the one now more closer to the light is starting to turn lighter particulary the top ones. So I increased the distance to 18" instead of 12". Let's see if they turn back green again.... The light reader right next to the...

It's the same strain. The plants with more light seems specklked with differnet shades of green and the veins seems darkest whereas the plants on the side have a more uniform darker green.

I have a cooled 400W MH that is around 12" from the tops. The temp is 88 with lights on and 72 at night. I have been observing that the plants in the middle of my grow room (4X3) have much lighter colored leaves compared to the plants more on the side of my grow room. Could this be due to too...

Thanks Videoman. I seeled up my room further now I can sustain above 1500ppm for 4 hours with 25g of dry ice. If I could just make it work for 8 hours that would be perfect. The plants really seem to like the dry ice they are showing a good boost in growth. Without the the fresh air running the...

Thanks Seedless! Good post! Why do you think 2000ppm CO2 is toxic to plants? I do not think that is the case. Some grow rooms run occasional 10000ppm to get rid of bugs. But your post does not answer my main question. How do I now all my factors are in excess for CO2 to have an effect... Peace

Hi All, Newb grower here. Thought this would be a good thred to jump in... I found the suggestions on the use of dry ice quiet helpful as I've been wondering about how to regulate the sublimation and the concentration of CO2 in my 72 Qubic FT (4x3x6) grow room. The problem I am having so far is...

Thanks BT DT! Yes you're right it is a 4000K standard MH buld. So you agree with my perception that I should go higher to around 6000K.How is this one on ebay: eBay: 400 watt MH Metal Halide Grow Light Bulb 400w BLUE spec (item 180130491941 end time Jul-08-07 21:15:00 PDT)

Hi Everyone! Nube grower here. I've just started my first grow project in a 2.5x4 Ft closet. Got a switchable MH/HPS 400 W ballast. Want to use MH for the vegetative phase and HPS for flowering. I read that phosynthesis requires light of 420 nm. So I am thinking anylight that focuses on...
