Yield from 1800watts

[New Holland]

I know this is abit like asking "How long is a piece of string". But I'm going to ask anyway.

 

Can some one give me some idea of the yield I could expect to get from 12 plants under 3 600watt HPS lights if I turn them to flower at 20" (finish approx 40"). I'm growing in 3 gallon pots with Coco and Coco A+B nutes with PK13/14 and liqued lead. The strains are 4 x Northern Lights/Bigbud, 4 Purple Power, 4 White Widows. I'm growing from clones. The seeds came from Amsterdam so I think they have good genetics.

my guess would be around 2lb-2.5lb, but it really depends on too many things to accurately guess

[Ragin]

Well It would be very hard to say unless someone else has grown with the same lighting / strain in a very similar way. I have not

[two2time]

i would have to argee with the others, to many things to accurately guess..

Theres 35 oz in a kilogram. But theres only 16 oz in a pound.

if ur ventilation is adequate, and temps within the optimum range you can get 1lb per light of a 600 no probs. 1.5lb per 1000watter is average here

Keepleft has handed me a challenge. lets see if I can reach 3 pound!. (48 oz).

 

Im using 2 fans. 1 for extraction, another for inlet. 160 litre/sec.

 

Temp is about 7c above ambient, which is 15 = 23c. We're heading towards summer, so night time temps will be around 20c which will give me bang on 27c. I've bought a speed controller for the inlet fan, just gotta install it. I can slow it down to raise the temps and reduce humidity

[loylty gets u nothing]

sweet man

i got 3 under 1 x 600

in a scrog hopin 4 a lb

each 600 should give u a pound

but it all goes on your skills

are gunna use any tecniques to increase yield??

grow diary??
