Crops

## What the hell is /crops/?

/crops/ is 420chan's board about growing plants of all kinds, though the board is dominated by marijuana discussion. However, if you're growing anything from strawberries, squash, and potatoes to mold cultures, mushrooms and algae you can post here too! /crops/ is a hybrid highway of knowledge to fill anyone's growing needs.

## FAQ

**Finally we have a place to write our FAQs!**

### Where can I get seeds?

Seeds can be found at a seedbank of course!

### How much bud will I get from a plant?

The question that all new comers ask; and the one that could never be answered. Pure and simple there are far too many variables to say one cannabis plant will yield you a said amount of bud. The grower cannot count their chickens before they hatch. What they can do is use techniques, tools and systems best suited to their grow area to maximize yields. Also check out this question answered quite nicely on RollItUp.org.

### Is this plant male or female?

Check out our Sexing page. But the plant has to be pre-flowering or placed into the flowering light cycle for it to show sex. If it has balls it's a male, if it has pistils it's a female.

### What kind of lights should I use?

Check out our Lighting page. You will need to use the right light for your space. A small space works good with a florescent light, an HID in a cool tube, or if your rich an LED panel. Large spaces should use HID light.

### Light cycles? What's that?

To achieve vegetative (just leaves/branches) growth in seedlings and plants the grower can use either 18 hours of light with 6 hours of darkness OR 24 hours of light with 0 hours of darkness. To make the plant start to flower and create bud production, the grower uses 12 hours of light with 12 hours of darkness. Growers generally say "18/6, 24/0, 12/12" in the [Light/Dark] format to discuss their hourly cycles.

### My plant is starting to smell! What can I do?

Get yourself a Carbon Scrubber or an ozone generator, but be careful with ozone generators, they can poison the plants!

### When is my plant going to be done?

Check out our Harvesting page. You will want to get yourself a microscope or jewelers lens something 30X or higher so you will be able to see the trichomes up close.

### How can I preserve my seeds?

Seeds placed in an airtight container stored in a cool, dark, dry place have the best chance of survival. (Seeds kept in these conditions can last for many years.)

### What is the absolute minimum lighting to grow a decent plant?

Vaguely acceptable but disappointing results can be obtained with a pair of 24W fluorescent tubes. This will get you a couple of proper bowls.
For something that's not a practice grow, get at **least** three 26W CFLs per square foot of grow area. This will get you actual smoke.
For those looking to actually have their own supply, a HPS light from 150W and up is recommended. If everything goes really well, you may be pushing an ounce or more per square foot in a screen-of-green setup.

## The Importance of Light

The chlorophyllic plants are autotrophs, meaning they produce their own organic matter with water and mineral substances from the external medium and synthesize them to organic materials.
This synthesis takes place in the presence of light : it is photosynthesis.
Two other conditions for this process to take place are : the presence of chlorophyll and carbon dioxide ( CO2 ), but we won't go into that much.
The first organic molecule synthesized during photosynthesis are the carbohydrates which accumulate in the form of complex molecules called starch.
The starch that is synthesized in the leaf during the day is hydrolyzed to glucose at night.
The production of organic materials is accompanied by the release of oxygen that is easily evidenced in aquatic chlorophyllic plants.
The plant ( as mentioned above ) requires light so that photosynthesis will take place, though it also depends on the luminous intensity of the light it is subjected to.

Normally, the volume of oxygen released by the plant increases as the luminous intensity increases, meaning the rate of photosynthesis increases.A high rate of photosynthesis means the plant is developing faster, though there is a limit to how much luminous intensity the plant can stand before it stops producing oxygen and starts to die.This is one of the reasons we don't put such large lights on smaller plants.

## Some words explained

*See Growing Techniques for more info.*
**HPS**: High Pressure Sodium. An efficient gas discharge type lighting technology. [Big Orange Street Lights]
**CFL**: Compact Fluorescent Light. A fluorescent tube that has a funny shape, and carries its own transformer etc. electronics in the base. Along with straight fluorescent tubes, CFLs are the lighting technology that only poses mild to moderate heat issues.
**MH**: Metal Halide. An efficient gas discharge type lighting technology. Particularly suited for vegetative growth due to the characteristic spectrum of conventional metal halide bulbs. [Big Blue Street Lights]
**MV**: Mercury Vapor. Almost the same as an MH, but slightly less efficient, and of a Blue-White spectrum closer to white. Almost interchangeable with MH lamps. [Big White Street Lights]
**ScrOG**: Screen of Green
**SOG**: Sea of Green
