We'll use 3 tents for flower and 1 tent for veg/mommies/cloning. Given the ease of the system and all of the money spent in automation, its really not hard. Lets look at what I have to do over a 3 month period:
Get 300-350 clones or seeds sprouted - 8 hours total
Veg for 2-3 weeks, which involves checking ph/nuts daily and water changes weekly. 15 minutes per day to check water and 4 hours for the initial sprout to veg transplant. The water change takes 30 minutes.
Flower for 8-ish weeks, which involves checking ph/nuts daily and water changes weekly. 90 minutes per day to check water and an additional 4 hours per week to account for misc. upkeep. The water changes will take about 4-6 hours to do because of 12 tubs and nut mixing and all that fun stuff.
Cutting/trimming -- Here's where you have fun.
Harvesting 17-20 Lbs, cutting, trimming. That'll take about 3 hours per pound, at least that's what I can do it in. If I use a machine to do the trimming, it might speed it up. That's just by hand. So lets assume about 60 hours to do it.
Once you cure it and its ready to be packaged that doesnt take much time. Lets say 6 hours for this.
What are we up to time-wise?
It's a fulltime job no question about that. Since each room is spaced apart start-wise, there will be continual work every day from each cycle. There will always be cloning, always be vegging, and always be flowering and cutting/trimming/drying to do. It wont be all grown at once. I'm sure that was common sense, but just in case.
Advanced Nutrients for everything, schedule is already done from their webiste for the calculations based on the 40 gallon resivoirs for vegging and flowering.
