You could always get a pack of one of the autoflowering strains breed it get a bunch of seeds then just plant a new crop every 20days, have 3 crops goin at the same time. Wouldn't have to worry about dif rooms as you could always have the light on 18/6 or 24/0 whatever you prefer.
or one space for seeds and veg and a space for flower and if you wanted to not buy any more seeds if you got a male you could breed certain buds and get more seeds.
Cloning is not that hard, if you take a tried and true method and follow the instructions to the T (of course if you don't have the exact lights you can always just use whatever fluorescent or cfls you have on hand), than you will have great success.
Try uncle al's Method https://www.rollitup.org/hydroponics-aeroponics/15030-batch-clones-rockwool.html
Should give you good results.
Trust me when i say that clones are the way to go if you want a perpetual harvest. They are ready for flower as soon as they're rooted, will not suffer from as much stretching, and you can select the strongest and most vigorous plants as mothers giving you more uniform growth. Not to mention you get all females (assuming they're cloned from female plants. =) giving you one less thing to worry about.
The fact of the matter is, I was once scared of cloning too, but the benefiets are too great to ignore, just be dilligent, patient, dont overwater and give your plants plenty of love and theres nothing you cant do. (got a little cheesy at the end there, but its true)
Good luck and happy growing.
these work really good! its all really about keeping the cuttings warm and not overwatered. this i went from zero success to about 98 percent, i had so many i was the one finally handing out clones.
