Dieharr

I made a grow closet similar to the "super-closet" but all DIY. The most expensive part is the lighting system but all the other parts could be found in the streets or on local offers/ads. For the lighting system, I recommend LED since it is very durable, it does not produce heat or noise, and it will not burn your plant/dog tail/kid's hands - or whatever would touch hit !

The quickest and easiest is to buy a small tent setup,with soil as a medium its easy to set up and to take down and there's no damage to house, everything is included ( look on ebay etc your'e local grow shop ). Soil is more forgiving for beginer's and contains enough nutrient's to start plant's off for a few week before any feeding will be necessary.I would probably choose CFL's as a light choice as it's not as hot ( good where kid's are concerned ) and requires less cooling / ventilation than H.I.D lights. Your'e biggest problem is keeping your'e kids away from them (lot's of hazards !!) You could lock your'e bedroom door ( the tent's do look wardrobe like !! ) even better put tent in loft/cellar, out of reach.

Have you considered Space Buckets? https://www.spacebuckets.com/ See also: https://www.reddit.com/r/SpaceBuckets/ They claim the total cost is about $100. I was going to try space buckets but then I built a hidden room behind a closet, added a 63"x32"x32" tent, carbon filter, etc and my costs are just under $700 but that includes $180 in hidden hinges for the secret door. I am thinking of setting up some space buckets for germination and vegetation then using the hidden closet for flowering. Knowing the children won't find the hidden closet is a comfort but surpasses "cheap." I would highly recommend looking into Space Buckets.
