We just returned from the Maximum Yield trade show in San Francisco and the show was great. Since returning home we have seen a great deal of traffic on our website and many new stores that have requested to carry our products.

Store owners: Please watch for a online questionnaire that may be filled out with important information that you would like potential customers to know about your store. Once this questionnaire is filled out and approved, you will be contacted to send a logo of your store and other pictures that you would want potential customers to see.

Any store owners who have not yet received a catalogue from us please contact the Green Planet Staff and we will send one out.

Thanks and happy gardening! - GP STAFF

Q: Should I use CO2 in my garden?

A: Carbon Dioxide (CO2) is a colorless, odorless gas that is found in small quantities in the air, and is essential for plant life, without it plants could not survive.
Carbon Dioxide will increase growth in green plants. Green plants use carbon dioxide and water in the presence of light energy to synthesize organic compounds. The green plant then converts the organic compounds into sugars or food, through a process called photosynthesis. Carbon Dioxide can also be a limiting factor as well, if the conditions to which the plant is growing in are not adequate the added C02 will be of no use.

Physiological evidence strongly indicates that most plants have the potential for increased production, but the extent of plant response is also dependent on such factors as temperature, light, nutrition, water, and carbon dioxide levels. Blackman's law states that the rate of any process which is governed by two or more factors is limited by the factor of least supply.

Elevated levels of C02 will of little benefit at low light levels or temperature. If your light intensity is raised or temperature for that matter, higher levels of C02 can stimulate new growth. Elevated C02 levels will also call for increased fertilizer and water requirements.

If you are considering C02 enrichment, there are a few things to keep in in mind. Enrichment of C02 should commence at sunrise or when your articial lighting comes on and cease during dark period. The average C02 level recommended is between 1000 and 2000 ppm. the objective is to keep a constant level in the atmosphere. A small unit can be operated continuously or a larger unit can be used and put on a timed sequence. In a situation where exhausting is frequent you may want to run the latter. After the exhaust function the unit can be cycled to replenish the C02 levels quickly to maintain excellerated growth.

Montreal Maximum yield indoor expo was a huge success!!
