Just curious, what does a kg go for out in aussie? If its high you might do just fine. Just find a grower whos successful on here at a similiar level and try to replicate his grow to the T. Dont be scared to ask questions, ppl here love to help.
Pounds of indoor go for $3200-4000. Outdoor $1600-3200 depending on quality.
Budget for two tents 1.2x1.2m. 1x400 hps & 1×600 hps lights. Fans & ducting. Carbon filter. Miscellaneous like extension cords etc. Medium. Power costs approx 40c kwh. About $6-7 a day for this set up.
Go with canna bio and you wont need a pH or EC meter just feed on the low side. Like 1/4 or 1/2 strength.
Figure on yielding 12 oz per 600w every 3 months conservatively. And you wont be growing Dec, Jan, Feb.
Your looking at $3000 before you harvest anything including power.
Watch out for rental inspections and have a plan to stash everything when they occur.
Cops will get the real estate to let them in if you get a "knock and talk".
Good luck mate. :)
