600w light SOG how many plants?

29 posts in this topic

How many plants can you put under a 600w lamp in a sog or scrog. Is there a plant per foot rule or something like that?

Cheers guys

12 square feet @ 50Watts per SqFt = 1 * 600Watt lamp.

:wink:

I have a 600W HPS (and MH but check my 2nd diary for details). Each 600W HPS is on a 2 meter linear rail mover. it covers a 1 meter by 2 meter tray filled with 21 flowering plants in a SOG grow.

Please think hard before doing sog, the plant numbers are scary. You can get about as much yield doing a scrog for the price of running a veg light.

These days an hps covers 4 x 4 quite well, 16sft @ 6 plants psf = 96 as opposed to 4 or 5 plants with a scrog.

6 plants per square foot?????? thought the norm for sog was roughly 1 plant per square foot!!!! being 16 plants in a 1.2 x 1.2

The actual definitions are blurred. sog used to be little or no veg time, a week at most which I doubt is enough for 1 plant per square foot.

Some experienced soggers reckon a half ounce per plant is the sign that you know what you're doing. That's 3oz psf 8 times a year, easy to see why the authorities penalise higher numbers.

iirc, the guru pH got 0.91 grams per watt per month using a modular scrog at 1 plant per square foot. The 12/12 stretch was what filled the screen rather than veg time.

In practice, it's newer growers that focus the most on yield, after 5 years or so many get sick of being chained to the grow or only toking heavy yielders. Lets' say you are ok for space and by chance hit on an easy peasy grow method that suits your lifestyle perfectly but it doesn't yield that great, neither does your favourite strain. You run an extra light to account for the yield drop and you get what you want plus an easy life for about a quid a day extra.

If space is limited then that's a different problem.

hmm I have a 400w light in a 4x4 area and I have .... um... lots!

I have I have 15 mature plants (26-30") 9 immature plants (clones) and 20 seedlings all crammed into the same tight little space. Its tight... but it all fits.

when its all setup right, its just like one 4x4 canopy of leaves.

Now, this is not a very good setup for most things I'm doing (or anyone else for that matter).. and its crowded because I thus far am only using one light. I'd prefer to have a seperate light for vegging and flowering.. which would allow more space in between the plants.

Ideally.. I'd prefer to have enough space in between my plants for no leaves to touch themselves.. or 10-12 " in between pots.

Will 16 plants per square foot do instead? Not my cup of tea but each to their own.

Doesn't feel right lifting someone elses pic so just posted the link. Not sure on site rules so changed http to hxxp.

wow. My apologies for doubting you lazi.

So, if my quick skim serves me right, he is getting a whopping 7 grams per plant. Idk, I kinda like my way where I get 45 grams per plant (dry bud weight) per plant and I can reach between all the plants, air can move and there is enough compost to make watering easy.

The point I'm getting here is that SOG can be many different things. It doesn't have to be the way you described below, as my own grow diary shows.

Please think hard before doing sog, the plant numbers are scary. You can get about as much yield doing a scrog for the price of running a veg light.

4 plants , just under 1meter squared , scrog.

about 6 weeks veg from very small clones.

ive got 2 meters squared under two 600 watt hps. 4 plants under each laamp but one side didnt take very well.

these are pics of the good side.

if you arnt in a hurry you dont need that many plants at all.
