Again with this co2

CO2 is calculated and measured in parts per million – ppm . Country air contains about 300 ppm. City air usually contains about 400 ppm. Most researchers put the ideal level for maximum growth rate at about 1500 ppm, or five times the amount of CO2 found in fresh air. Inexpensive CO2 Tester The simple inexpensive test kit pictured here is available from a number of garden supply distributors across the country like cannabis seeds. Each glass tube is good for just one test, and costs about $7.50. This is a small price to pay for the benefits that come from proper CO2 enhancement, no matter what size the garden.

The goal of the closet grower

The goal of the closet cultivator is to grow plants which yield a large crop of sinsemilla, the unfertilized female flowers of the plant. Usually male and female flowers grow on separate plants. By removing the male plants from the garden, the females remain unpollinated. Pollinated plants put much of their energy into producing seeds, rather than bud growth from semillas de marihuana. Unpollinated plants grow clusters of flowers over a period of 4 to 8 weeks. Within a few weeks the growth takes the shape of a bud. As the buds ripen, the clusters of flowers grow thicker and the resin glands found on the small leaves and branches begin to swell as they fill up with THC. When it is ripe, the bush fluoresces with 10,000 points of light.
