The rest of this information may not pertain directly to growing marijuana, but rather to pot in general. You will certainly find some interesting stuff here, as well as links to other growing and marijuana pages.
Mr. Monster's Screen-Of-Green Here's a simple drawing of a Screen-Of-Green setup that incorporates a venting system to remove heat from the growing area.
Female Pistils at Internode PairClose-up of the intersection of two opposite nodes. The pistils are actually at the base of the side shoots, which have grown just above the large fan leaves.
Female Pistils at MeristemPistils are developing around the nodes on a female plant near the main growth tip of the side shoot. This area will develop into the large cola bud cherished by growers.
Strain Identification Photos A collection of pictures of the leaves of some of the major strains. You may find this helpful in guestimating the origins of your unknown seeds.
Female Colas in BloomA great picture of the tops of two plants near their peak of flowering. You should read this description after you've looked at the photo.
Bottle Hydro SetupA very cool hydroponic ebb&flow system using PVC piping and what appear to be bleach bottles.
Growing Closet (jpeg)This 31"w x 50"d x 80" h growing closet has been separated into two areas, one for cloning and the other for flowering.
Clones (jpeg)These clones were taken from the lower sideshoots of a mother plant. They have been placed in rockwool cubes and are showing canopy growth after 14 days.
Male Pre-Flower (jpeg) Female Pre-Flower (jpeg)If you're trying to get a grip on the difference between male and female flowers, check these two photos out. The illustrations show the first evolutions of differentiated primordia. These will mature into staminate (male) and pistillate (female) flowers. A grower can safely allow flowers to develop a bit further before removing males from the garden.
