    Is it possible?

    If you were to run a very tight SoG setup, taking clones and flowering them straight away. 48 Plants per sqm, Aeroponics and a 1000W HPS over 2 sqm.

    So basically each sqm would have 500W and 48 plants which means each plant would have to yield 20.8 grams every two months.

    It doesn't seem that impossible to me, the only 'questionable' thing is 48 plants in 1sqm, but remember they're clones and flowered straight away and you can cut away any pretruiding leaves so you're only growing the top/main kola. Each plant would have 14.5cm x 14.5cm (5.7 inches x 5.7 inches)

    Let's also, for arguments sake, pretend that we have perfect genetics, perfect growing methods, and taking large clones.

    Or am I living in dream world? :-?

    sorry but i think youll be lucky to get 10.8 grams per each clone going straight to 12/12

    i took a small clone from a plant that just starting showing pistils and put it straight to 12/12 its budding nice it small though but i think 10.8 grams is more realistic

    i managed 11.4g from a single stemmed lollypopped DNA SOUR CREAM clone in a 1 litre airpot that got flipped to 12/12 once it hit 5inches tall.


    i think you're dreaming but would love to be proved wrong if you try it and it works.

    also 1x1000w is only good for 1.5x1.5 max

    4.5 lbs off a single light? Pretty sure that's your imagination. Would definately need to go with a vertical set-up and long veg if you want to hit that as well. 1kW light just doesn't have the coverage.

    I've never really seen anyone consistently yield more than heath robinson. Here he managed 4.65 lbs (2083grams) off 3 x 600w. One of the most impressive grows I've come across when it comes to g/w and that's only 1.15g/w. He has another that hit 1.49g/w but still that's absolutely amazing. This guy is a pretty well known longtime professional grower that I assume holds a few records. If he can't come close to 2g/w I really have a hard time believing it's possible with the current lights. http://www.rollitup.org/grow-journals/101347-critical-mass-tree-grow-x-2.html

    But if you take big clones and grow using Aeroponic, is it really that unrealistic to hit 20g? :P (Al B Fuct, the guy that made the 'get a harvest every two weeks' thread took big clones and flowered them straight away, he managed to get over an ounce per plant 30+ grams)

    Probably am dreaming.. but I don't think getting 15g+ would be that unrealistic if you perfected everything (Which would be 1.5 gram per Watt)

    Also, can you really use the Watt-Per-Gram term when you're taking clones? Technically you should be able to get more than 1g per watt because the plant has already "gained watts" as part of it's mother?

    Really? Al B Fuct, the guy who created the 'get a harvest every two weeks' thread used 1000W for 2sqm and he did pretty good. With a good reflector and cooltube.. and maybe running multiple setups next to each other (So that 'excess' lights spread over to the next setup instead of being wasted) 2sqm should be ok, shouldn't it?

    albfuct varries his numbers a bit. on grasscity he stated "Even powerful HPS lighting can only penetrate foliage so deeply, so a metre tall is just about perfect. I find that big lights give better bud density, so I use two 1000W HPS, one over each pair of 820mm^2 (~2.7 feet^2) flood trays." http://forum.grasscity.com/advanced-growing-techniques/156593-get-harvest-every-2-weeks.html

    Hard to fit 30 plants in a 2.7x2.7 flood table - not to mention the 1kW lights each covering a 3x3 canopy versus a 5x5.

    Please prove me wrong though on the 2g/w

    Actually, he has a 900mm x 900mm tray (He mentions later on somewhere that his original estimation was wrong). You don't happen to know any similar setups to Albfuct? I do believe that SoG is the most effective method.. but there doesn't seem to be a lot of 'good' growers that use it... maybe it's not the best then?

    Don't worry, if I ever achieve 2g/w i'll be sure to make a big deal out of it, hehe :)

    Technically vertical lighting either stadium or large plants should yield the best. I would say SOG perpetual to be the second best when it comes to yield but much easier to operate. I do know many people that do 4x4 1kW sog trays and they pull very well. Know several 3x3 600w growers that pull a bit better. 1oz and even 1.5oz lollipops are very possible but you generally can't get much more than 16 per tray without sacrificing yield per plant, ~ 1 lb per light.

    I'm just saying that if someone could pull 2g/w they would be screaming about it all over and everyone would just blindly copy them. If you hit 1.5 pat yourself on the back real well. If you hit 2/w tell NO ONE but message me all info so I can copy pronto.

    Yeah, I was going to suggest vertical growing, as well. If I remember correctly, I followed a grow where a guy pulled 2.64 gms/watt from a 600 HPS. Hey, isn't there a thread around here where a member promises like 3.5 grams/watt if you follow his methods? I looked at it before, and I think that was the number given, remembering that it was a pretty good setup, involving a bunch of plants in 5-gallon buckets, LST'ed around the rims of each, before flipping to 12/12. Idk about 3.5 per watt, but at any rate, it'd do well.

    Yea stadium would be the way to go. Especially because you pack them in with very little to no veg and your using the light to it's full potential.

    If you don't go vertical, invest in a light rail, and make your area a little bigger. That's one of the easiest ways to improve efficiency, I love mine.

    I was about to say this. Light movers are great and really increase coverage area/yield for cheap.

    ^Sweet, that's the grow I was talking about. Wasn't quite the 2.64 I thought, but still impressive.
