.... then you gotta do seeds or clones again. Seeds means another 20wks - Clones that save you 4 weeks are worth $100 each or if normally priced will take you at least 2 wks to size up.
.... forget to factor in $60 seeds at the start
If you do your own cloning then you need Option extra #2 PLUS one more light $100 >>> $820aud (or about $640usd)
Plus I recks $100 for 10 feminised seed (with post and insurance) >>> $920 ($750) then using the 2nd light on "MH tubular retro" globe and heater mat to generate under.
So now it is 2 cupboards.
Oh, yes, to backtrack to Crop1 form Cupboard1 under 250w you'd get 60g minimum > most will smoke a g/day so smoke for 2 months (cheapest scenario must include worst outcome).
With generation time you'll be out of smoke for 4wks roughly - smoking leaf...... it's good to get off the strong stuff ...... rollercoaster
Oh yeh, you should start with a Bloom Wardrobe as described above WITH a flourescent / led generator station IN ANOTHER BOX !!!!
You might find the grow getting into your Bathroom and Laundry.......
