Как понять выражение "урожайность огурца с 1 м2" ?

cucumber make 6 till 8 fruit per week,  in general. WITH A  SUPER VARIETY 

1leave give approx 200 gram. so simple calculation will give with enough artificial lighting  min 18000 joules per day.(MINIMUM )

52 week is 8 leave per week is 8 fruit per plant per week, 

8 fruit of 200 gram per plant X 2,7 plant per m2.  + 4.32 kg per week

52 week x 4.32 =224 kg per meter greenhouse 

theory yes, but we must start up. less production. after week 8 the plant grows slower, we must change plant 4 times. max period 13 weeks in this situation. by planting we loss time. so we can realistic 46 week produce. that still 199 kg / m2. we must calculated10 % loss, broken heads, fallen fruit. and more than approx. 179kg  we must remove the first 6/8 fruits, plant slow down on the end. stem to long and ageing.

So if we do everything good - climate, labor, harvesting, CO2 we can make 160 kg/m2.

But no problems, no diseases .

Remember a new greenhouses, clean glass, good, screens, good labour, good heating - all must be perfect, and we must be luck.

But I do not sign for it!
