hey bro. um i really cant make suggestions to a company wit grow boxes as i dont use a grow box. but u can make a grow box urself and thers tons of info on RIU wit DIY growboxes. my plants wer vegged bout 1month and most wer round 12-14inches. if space is an issue for u, u cood try 12/12 from seed or u can use cfls to veg using all 6500k, that is wat ive been doin using all 6500k coolwhites insted of mixing em like other folks. i find that using all coolwhite 6500k for veg keeps the plants nice and short cux wen u flower they will double and triple in size anyways. as for oder i bought a negative ion/air purifier wit carbon filter wen it was on sale and i use inscence or scented candles and that werks prtty well for me.
