Strain for very light intensive room 100.000 lumens/m2

[Heavy H]

Hi all,

looking for a strain that will perform well in a very well lit room, one 600 watt greenpower bulb producing 90.000 lumens that will light an area of under 1 m2.

Will use highly efficient super oxygenated bubblers and add CO2 to ensure max usage of the light.

I want the strain first of all to be a great producer at high wattages, it also needs high potency and can't be too smelly or really hard to grow.

Current candidates are The Hog from TH seeds http://www.thseeds.com/pages/en_hog.htm and Grapefruit from Female seeds http://www.femaleseeds.nl/Engels/index.htm.

I'm thinking a sativa might be the best producer at wattages. Any ideas on this?

Hmmm, well, i'm actually giving away a few seeds to a couple experienced growers wanting to try a new strain.... I'm growing it at the mo (1st grow) its some dank bagseed my 'mate' grows...

His last plant from this strain: (vegged under 2 x 80w flo tubes and flowered outdoors) - so imagine what this kind of lighting could produce...

First off all plants will ALWAYS do better with more light (lumens). Lumens equal more bud. 600 watts is not that big and you must consider how many plants you will have and how tall they will be. Unless you tie them down then it will be hard for effective light to get down towards the bottom parts of the plants if you go with a sativa strain. For this reason I would tend to go towards an Indica strain which stays shorter and bushier. It also usually have a shorter maturation time. Also, potency and yield are not always in a direct positive relationship. Some of the most potent bud does not give:thumbsup: high yields. Just like when buying MJ...do you want quanity or quality.

Maybe I should have made this a bit clearer. I'm an experienced grower looking for some very specific information - which plants will grow well at very high wattages.

Actually, a 600 watt lamp with a greenpower bulb ( the newest generation agricultural bulb from Philips, not street lightning like some people use ) _used just on under 1m2_ will give buttloads og light, much more than average. Sure 600 watts for a grow several square meters isn't a lot, but then again, I have several 600 watters. :-] Light usage schemes go something like this ( from memory ):

30.000 lumens/m2: Minimum for growing compact buds.
50.000-80.000: Ideal for most plants.

Above that you have diminishing returns on number of watts per m2, then you have a stage where plants are actually hurt by excessive light, and then you have a stage where you kill your plants from all the light ( try putting 0.3m2 of seedlings under a 1000 watter and see what happens ).

Grapefruit ( 90% sativa ) is only 8 weeks. I'm growing it now, and it looks good. Sure the bottom branches have small buds, but I cut most of them anyway. It's very practical for keeping airflow under the plants, I have an extra oscillating fan there. But yeah, I considered some more extreme sativas like Neville's Haze and Neville's Haze x Zamal, but they were just too long too flower.

So my question is which kinds of plants can profit from the levels of lumens that usually either hurt the plant or just don't give a lot of extra buds compared to more normal levels of light.

Some people say sativas because they grow in tropical areas, and they have the most light. However, a lot of indica's grow in mountainous areas where the sunlight is much more intense than at groundlevel. So really it's hard to tell.

10K lumens per sq ft (no idea what you call that over there) is not extreme for any plant that I have read. It will only mean bigger and denser buds. ONe grower here who I will not mention for obvious reasons shoots for about 14K lumens per sq. ft. and grows buds the size of your forearm. I'd worry more about controlling heat than I would having "too many" lumens per sq. ft. But, as an experienced grower I am sure you already knew that.

Hell, on G-Kno's video the guy used a 600 watter for every Aquamist system and they are only 8 sq ft each, and he rocked the audience with his buds. Strain was NL by the way.

Ok thanks man, I appreciate your answers. I used to read some schemes of how many watts people used per sq foot on alt.drugs newsgroups many years ago, and as far as I remember, 10.000+ lumen per sq ft was pretty extreme.

Guess I'll just try to flower 'em and see what happens. Ofcourse at those wattages CO2 and really superefficient rootmedium is a must, otherwise the extreme amounts of light will mostly be a waste.

Not surprized his buds rocked... at three times as many watts as you need and aquamist systems, they should!!

Yeah, heat will be a big issue. However I'll use digital ballasts which produce less heat, and also probably use coolshades too. If it's still too hot I'll get a bigger outtake fan. And if that doesn't make it run smoothly I'll run the flowering at night and add a huge ass intake fan too.

As I stated before.....the more lumens the bigger and denser the buds. There is no strain that says "oh, not that much light"! Remember you are trying to replicate the sun and if I recall correctly the avg tropical sun emits like 10,000 lumens per square foot. In a square meter thats approximately 90,000 lumens. The only thing with more light is increased heat output (wattage). If you can 2000 watts on one plant that plant, no matter what the strain, will grow bigger denser buds. I'm sure there is a point where growth rate is maximized and diminished returns is apparent, but this is not a point that most growers reach or are even aware of, if at all. Basically, the more light you can provide the better yield will be had.
