What do you need to know about doing a sog grow ?

I ran eight 4 x 8 flood tables sog for 5 yrs & am pretty well versed in all aspects of sea of green , i can give you some tips right off the bat , clone selection is paramount .

You want cuttings that are 6 to 8 inches high with atleast 6 node sites & no side branching ,after the clones are well rooted put them in net pots 5 inches to 8 inches & use hydroton or whatever rock type medium you chose , net pot size is important to add stability where you dont have to tie massive colas up after a month , i use the 5 inch pots & a mix of hydraton & gro rocks .

Veg time will not help yeilds it'll only fuk up the clone , if you use the big cuttings with 6 to 8 nodes you want zero veg time , if grown properly & rez temps stay at or below 65 degrees harvest will be in 8 weeks & you can expect yeilds of 2 to 4 ounces per plant , i get right around 1.5 grams per watt every 7.5 to 8 weeks .

For a plant per sq ft ratio i load 4 ft x 8 ft tables with 50 cuttings , when finished the plants have about a half inch to 2 inches between them , dont get greedy & overload the table as air flow thru a canopy of tightly packed colas is crucial , i have a box fan blowing fresh air thru the canopy at all times , bud rott & powdery mildew will take over a sea of green in a matter of days if it dont have proper air circulation .

Ive found that 600 watt hps work best for sog with big 3 x 3 reflectors , with 600's cooled right you can let the plants touch the glass with no burn , 1,000's are so hot after you raise them 12 inches away you get less light than with the 600's a half inch from the glass , i put all my 1,000's away after comparing one table of 600's against them .

Best results are achieved when all the plants go in at one time & come out at the same time vs staggered harvests , reasons being light height from full grown plants will cause stretching in freshly planted cuttings , if you must stagger harvests then keep ppm's low around the 700 range so you dont fry the new cuttings .

I prefer flood & drain over DWC ten fold with sog , i like the stability of the grow platform , i like having the rez free of root mass .

I just popped off a bunch of shit in random order off the top of my head which i consider the basics , if you have specific questions regarding sog methods fire away , its how ive grown the past 5 or 6 years after spending over 30 yrs growing soil .

This is very very helpful. Were you using only 1 600 HPS?

I will be using LED and have a 450 watt but am thinking up upgrading to a 750 real watts.

I will keep them a bit apart for air flow.

Legal with max of 49 plants do a sog . Now if you had space and lights I would just grow regularly . Divide all my rooms . Have 25 in flower 10-15 finishing every month , have my veg room with all replacements and a couple moms . Quick $ is sog .

Good to know. I have a grow room of (6.5x4.66x7 f) which is 30sq feet. So ill need quite a bit me light correct?

I have heard black dog are just rebranded marshydro, but they actually recommend (BD), something like 40-60 watts per sqft, which is similar to hps, so you could potentially get good yield/space if you follow the recommendation. Most LED growers I've seen top out at 35watts per sqft. I don't think that's enough light

For LEDs I run a minimum of 50w per sq ft. And max of about 60 true watts, beyond that you really start to pass the point of diminishing returns. Weather they are or are not rebranded mars hydro, light spectrums are just a matter of changing out some LEDs. All I'm saying is to a certain point more light is better.

Yes I know, so im guessing 2 750watts so 1500 actuial watts which is 50watter per sq foot.

No i run three seperate 600 watt hps in large 3ft x 3ft reflectors for a total of 1,800 watts hps per 4ft x 8ft table containing 50 plants , harvests of 6lbs to 6.25 lbs per table every 7.5 to 8 weeks .

I have no idea how LED's spread out for coverage or light from canopy distances being ive never used them , my grows are hps from start to finish .

Now I don't grow weed so don't quote me, but I always read that sog/scrog/trees all yield the same in optimal conditions, that light usually is the weak link which will determine yield. The difference being veg time, so sog could yield significantly more per year.

Fwiw, the government found 2000ppf was the maximum light weed could handle at like 80 degrees and 1200ppm co2 if I recall.

Makes sense. Ill likley for the first time not use all the space. but ill need 1500 watts or so total.

If they are being advertised as 750w led panels you should realize that 99% of all panels are being driven at no more than 60%. So that 750w panel is only producing just quick math in my head about 450 watts or 900w for both panels best case scenario.

Your tent will run cooler save you on electricity . Or run cooled 600"s like the well versed sog grower above us mentioned . 2 of those and 50 lil guys !

750 Actuial wattage. Im wella ware of how LED works on that scale and advert wattage.

Just went and checked, I wanted to see their specs so they are being driven at 50% which is great for longevity. That's one hell of an expensive light though!
