This is my first Sea Of Green grow journal and I will also be explaining the SOG method and how to set up a SOG grow for yourself.
What Is A Sea Of Green?
The sea of green method uses many small plants instead of a few larger ones. Plants are given a minimal amount of veg time in a SOG system. The idea is to have a level canopy made up of single colas and minimal side branching. Because they have a short veg time or none at all, they can be planted very close together often at 4 or more per square foot.
SOG Vs SCROG
People often confuse the two. A SCROG or screen of green is just that. A screen is used to pull branches down and control height. SOG grows generally dont use a trellis because plant size is controlled by density and veg time.
SCROGS have larger plants and plants are trained into the net whereas SOG grows use minimal to no training at all. Plant count is also much higher in a sea of green grow.
If you are growing in a 2 gallon pot or doing LST or other training to control plant size you dont have a true SOG. You just have a grow with smaller plants. I see a lot of videos where people mistakenly call their grow a SOG. There is nothing wrong with a hybrid system but this about growing in a sea of green so we need to make some distinctions between systems.
Sea Of Green Hydroponics
Hydroponics will give the best results for a SOG. Because of the large amount of plants hand watering will be difficult. As the plants get bigger they will need multiple waterings every day. You will want a system you can automate. You can use aeroponics or a top feed drip system but flood and drain is the easiest to set up and maintain.
I would not recommend growing in soil. You may be able to use coco in a SOG but I think hydroton will give the best results and it is reusable too.
Sea Of Green From Seed?
Typically a SOG is grown from clones. The provide better uniformity and stay smaller than seedlings with a tap root. They are also ready to flower much faster than seeds.
Can you grow from seeds? Sure but you may not be happy with the results. If you have a strain that grows without much variation between phenotypes it might work out. But usually some plants will be taller and some shorter and some may branch more heavily than others.
The whole idea of growing in a SOG is to get an even canopy made up of single colas. This will give you premium buds that get good light and eliminate lower pop corn buds. Growing from seed really defeats the whole purpose of a SOG grow.
Best Strains For Sea Of Green?
I am not going to recommend any specific strains. What you want is a strain that makes a dominant main cola. Heavy branching strains are best avoided. Usually this plant is an indica or hybrid strain although some sativa strains will also work. Early maturity is a plus and it should not be hard to clone. I would really recommend growing a strain you are already familiar with.
SOG Grow Week 7
Plants are now at 7 days and growing well. They are stretching and growing some side branches. I think in a week the canopy will be pretty full.
I started running CO2 about day 4 and the plants really seemed to start showing increased growth almost immediately. Right now I am only flooding once a day and the plants are on a flood mat. It stays moist and I really want the roots to grow down into it. So I am holding back on flooding more often.
Nutrients have been raised from 800 to 1000 ppm and the plants look a bit hungry. I just changed the reservoir and will give the plants a few days at 1000 ppm before I decide to bump things up again. It looks like the 2nd tray with taller strains is a heavier feeder than the tray with the MAC 1 and Death Bubba.
MAC 1 At 7 Days
Flowers! Sea Of Green Grow Journal Day 13
Things are going well. Flowers are here and actually some varieties were showing on day 9. I will be putting up a trellis net because plants are getting tall especially in the 2nd tote.
Plants are being fed at 1300 ppm and a pH of 6.0. So far I am not seeing any signs of too much N like I had in coco so I am loving the growstones. These plants are being fed supplemental CO2 at 1200 ppm.
SOG Day 17 Leaf Strip
Plants are growing well and there are a lot of small lower branches that need to be removed. Time to open up the canopy to air flow and let more light down to lower buds.
Sea Of Green Day 21 Leaf Strip Results
Plants have fully recovered 4 days after leaf stripping. Light penetration and air flow were greatly improved and now the plants can focus on growing buds instead of leaves.
