What is the Sea of Green Method?

[Medical Marijuana]

(Excerpted from SCW's Fundamentals post)
The plantlet sea of green method was developed to maximize the speed of cannabis growing in limited height situations. In a typical sea of green setup of this type, clones are planted at densities as high as 9 per sq. ft. Within a short time after being established, the lights are switched to a 12 hour dark period.What happens to the planted clone?

The clone could just sit there, stretch a bit under the light regime, and flower, producing a tiny little bud with a couple of seeds. But that rarely, if ever, happens. Instead the clone takes off in a rush of growth, forming a woody main stem and branches. If the plant is suitable for sea of green growing, it will stop short of the lights and flower. Most indica dominated plants stop short enough to be grown using this method. That process is at the heart of the sea of green method, as it results in the smallest possible plant flowering in the quickest possible time.

Note that SOG plants are really just "an apple on a stick," that is, the main cola, and perhaps a side bud or two, are cultivated.

so how long after i root should i start flowering and how tall should they be. 3 inches or 4? If they are like 3 inchs when starting to flower what should be my pot size all the way to finish?

This is completely up to u. I suggest square shaped, deep pots, no larger than 3 gal. U can pack em in tight and don't have to worry about watering that as frequently as smaller pots (1 gal). Starting at 3" (on indica dominant strains) U can get away with 1 gal conatiners, but have to water frequently. If they were clones taken from mature mothers u can start them as soon as the root system seems strong after transplanting.

If you wait for them to reach 12" by the time they finish they will be around 18" or 20" and will yield quite alot more.

i have been waiting for my clones to get to 12 inches but they are really going slow. I have them under a 400 watt MH and they seem stuck at 8 inches. i was wondering if i put them under my 6oo hps will it be better, or do you think the 400 MH would make them grow faster?

[BWC BayArea]

HPS will cause more stretching and should be used for flowering. MH are typically used for veg and promote compact internode spacing as opposed to stretching. It may be genetic issue. The plants may be meant to be smaller plants, especially indicas. Don't think either type will make a plant grow faster, the higher wattage will provide a brighter light which provides a more intense life spectrum which in turn produces more usable light. U start feeding nutes yet?

Wheres your PH at.

Would a combination of MH and HPS work as well as just one or the other alone?

The combination of the 2 lights would mean more light output so 2 lights better than one in that sense. However mh is only really suited to veg so would probably be best to run 2 hps if u were going to run 2 lights. This would mean you could complete the whole grow without swapping bulbs.

Also you would have to take into consideration the extra heat that running an extra bulb would bring. Especially in small unventilated areas. Cooltubes are good at removing excess heat with proper ventilation. It all depends on how many plants you are growing and the space you are growing in.
