@Honkytonky, now, After 2yrs of attempts and errors, between 10 and 15gr of clean buds each (with last cycle i filled the black tray with clay pebbles, roots health and harvest seem benefited from It). Yep, smell can be a problem but I have never looked for a solution. That dude with a DIY extractor in other diary inspire me for the fan (a 15v PC fan) that i have installed on mine for humidity control... maybe can work but i think only a closet with a proper extractor can solve problem completely. Also a low odour strain can help ( i had grow Northern Light Auto (RQS) that was almost odourless but gave me a lot of leaves and weaky buds).

@Honkytonky, yep i have a Linfa but i "pimp" it :sweat_smile: due to try to fix some issue i had: added a fan for reduce humidity to avoid mold and an heater thermostat for water tank (sometimes i had 16° water temperature ). Also i manually give nutrients and try to replace all water with fresh every week. About nutrients: I recommend you to check at each cycle that the small pipes of the automatic feeding system (not the black one use by Linfa for water ebb)are free of obstructions that could be created by fouling, u can find it by unscrewing the white panel on the back of Linfa. About strains: I try Royal Dwarf but with Hulkberry Auto and LST tecnique i find my path, usually i grow 3 of them. Also with Tropicanna Poison Auto XL(!)(Sensi Seed) i had a good fruity harvest.

Hi Honkytonky, I think you have to pull out the adesive layer on two removable panel, cause under that there's a mirror surface that improve light spread ( or you have a 70w linfa model?). P.S. For my experience, only full sativa strain had issue with little height of Linfa because stretch is however limited by the little growth of the roots.
