I'm def in for it.
What's the strain?
What's the strain?
10 lb x 4 plants is 40 lbs.
40 lbs x 450g/lb = 18000 grams
18000 grams / 8000 watts = 2.25 g/watt
very interested to see this. Also this may be a bit hard to judge, some skeptics may question yield numbers but anyways I'm still interested to see some big trees. Way to put it out there D's
I assumed that DD ment 10lb from the room not per plant, 10lb per plant is gonna be crazy.
4540's g's from 8kw of light with co2 and 6kw of air con is very poor.
You might as well air breath and triple you g/kwh.
I have never grown a plant bigger than 2.5lb's before so this I'm unsure of the logistics but 40lb's seems a lot to take from 8kw of light without it being a coliseum style grow and 10lb's seems too little.
I would have though more like 16-25lbs in total, real high yielding maybe 30lbs tops.
That of course doesn't take into account the power from the air conditioner, I feel you should always factor every unit you're grow uses into those calculations for them to have any meaning.
4 ton of air con in the UK would cane ~5-6kw on it's own, I don't get why you guys don't use air cooled tubes what you lose in light you will gain in reduced leccy usage bothered about the glass robbing light use 1.5kw it'll pay I'm certain.
quick rough calculation 4000btu's * 8 32000btu's basically 3 tonne of that air con runs whilst lights on or 3/4 of 6kw 12/12 in flower which gives us 4.5kw/hour + 10kw/hour for the lights, pumps, fans, chiller so round up to 15 units an hour lights on.
I think 10lbs is 4.54kilos so 18.16 Kilos or 1.2g's/w
g/m3 of course has it's own merits beyond g/kwh.
All calculations should be g/kwh really when dealing with leccy that's how a professional greenhouse growing veg under lights will work.
I love doubleds grows but air conditioning isn't free and efficiencies need to take this into account otherwise it's not a fair comparison of one system over another.
I assumed that DD ment 10lb from the room not per plant, 10lb per plant is gonna be crazy.
If my memory serves me right, i think doubleds had a 10 plant room that pulled 42 lbs (yes/no?). Thats a pretty good start... :harvest:
A 3 lb plant is about 6 ft tall and 5 ft round.Going with pure commercial strain Ms walker was 3.4 avg 5' tall 5' wide. Tom Hill had a ten lb outdoor plant that would not fit in my 2 car garage. You pull this off I will buy you a drink while listening to songs written about you.
I would keep them low and wide as my theory is that plant has problems pumping up that many gallons/lbs of nutes. I wish you luck and no equipment problems. JK
