LST, Scrog or nothing?

[Heart Of The MJ]

Hello guys, so I have 200cmx150cm and 210cm tall tent with 2x 400w HPS. I have 16 different strains, and im thinking now, what grow method should I use to get best yield? I was thinking about LST. Give me some advice please Oh and I bought these: http://www.hydroponics.eu/co2-release-systems-c-18/co2-release-system-s-20/co2-tabs-60pcs-1190.html

How should I use them? And then? My buddies are only 2-4 days old just lowered temp in tent from 30 to 27

With that many plants I would be inclined to say just go Sea of Green, but I am still a noob so don't take my word too seriously

Please someone give me advice

Is 16 plant enough for SOG in 2m x 1,5m growbox under 2x 400w hps? Please someone give me advice how to get best yield at my situation My plants already 3-4 days old, ~like 5 cm tall Everything looks good at the moment

16 plants in 3 square metres is going to get awfully crowded very quickly.

Are they all females? Or do you not know yet?

If they are all ladies, I'd put them into flower before they get to the 6-7th node to avoid jungle syndrome. As you have several strains, SOG will almost certainly end up with canopy height control problems. LST is the way to go - some growers start when the plants are itsy-bitsy small The key is to maximise the light you have by having an even canopy.

The CO2 is a waste of time, but at least you didn't waste too many bucks on it. Concentrate on good ventilation and temperature control first, although it sounds like you already are!

The best yields come with single strain grows, with identical clones. It also usually takes a few tries with a strain to really get to know it's growing pattern so the space can be filled in the most effective way.

I've just tried two different strains in a space not dissimilar to yours. It's a pain in the arse coping with the two different stretching patterns, not to mention the fact that one strain produces big colas, while the other prefers to sprout hundreds of golf-balls!

Pictures would make this a whole lot easier to determine what strategy you should use for maximum yield

Why?

The OP's got a stack of babies, a 1.5m by 2m tent and control over his temps. A picture won't help at all yet.

So best choice for me would be sog? hmm. and why you are saying that co2 is waste of time? ive heard a lot of people are using it and its good for plants

Those tabs are a waste of time and money, imho.
Unless your are shutting off the exhauster during CO2 application, it's just going out the tent as quick as you can generate it.
How do you plan on keeping the CO2 in the tent or maintaining a concentration of say 1,500 ppm?
You gonna buy a $500 CO2 monitor to watch your $30 tabs go poof?
Stick to the basics and leave CO2 to the big boys.

Ok, thanks for tips guys
