The FK is award winning but there is the obvious reasons we shall leave unsaid as to why you might feel this is not an appropriate choice (I imagine the same reason you left their firm's name out of your post?). I must say that although I empathize with this view I have had occasion to run their gear recently by virtue of the beans 'falling off the back of a truck' and have been pleasantly surprised with the results. Their Strain Hunters Money Maker(basically remix of Master Kush) ran at 0.9GPW and The Doctor(basically remix of Great White Shark) ran at about 1.0GPW. The FK is one of the only genetics they carry that I MIGHT hand over actual money for. Again, it's more the social ethics that would prevent me in any case, not the genetics.
The Blue Cheese; well if you're after true cheese there really is just no other for authenticity but the UK version (the Exodus cut that others sell, ALLEGEDLY), where the strain originated. Have a look at UGORG (underground originals). I have seen some EXCELLENT examples first-hand from UGORG with Cheese and Blues, also the Psychosis is obviously top-shelf, although I don't know if UGORG themsleves would recommend any of them as beginner strains, certainly worth a chat with them though.
The Grandaddy can be a finicky producer from what I've seen, although I've unfortunately never had the pleasure of running her in my room. Mr Tight (renowned Youtube grower and all-round consumate professional hobbyist) loves this strain but says that in his rooms it is expected to only produce 60-80g's, while most of his alternate strains produce twice that amount nearly, 120g's. Beautiful quality though.
How much light you be putting in that tent? How long you want to veg for? To really fill that tent with four plants; I would think you're gonna be looking at AT LEAST 6 weeks veg time... I grow in a custom box about twice that size (140 x 225 or so) and with two weeks veg I can get thirty girls squeezed in that yield approx 1.1 - 1.2 kg AT LEAST (ABSOLUTE minimum for ANY strain is 0.8 grams per watt; max. I've had so far is about 1.4 GPW), and end up about a meter tall, depending on strain. This is under 2 x 600w. Any help I can offer you mate, don't be afraid to ask; I was seeing you were struggling to get some advice going eh...
Nice one
