    I am satisfied with the results. I spent less on the entire setup then a pre-made LED lamp would cost. Plus a wardrobe is more discreet then a grow tent

    Stinking up the place can be avoided if you build a carbon filter. I held a house warming party for my colleagues at flowering week 3. Nobody noticed, but still it was super stressful for me
    I did have to shut down the ventilation before they arrived though, the wardrobe does have a steady hum, fridge-like i could say.

    I agree that a wardrobe is more discreet than a tent, believe it or not i had a 9.5oz plant in a wardrobe in my living room with a bunch of peeps round and no one ever knew!! Mine was little bigger than yours tho and i had 5” carbon filter on it and a 400hps !

    I grow in a hot water tank cupboard (Possible a UK thing?) I've played with just about everything you can do in a small space in my 8 years of indoor growing...

    My goal was always to build a DIY carbon filter... I've tried them all! Seriously! They don't work

    OK... Actually, they do work... with shite lighting! Any decent plant will overwhelm the above DIY filter within an hour

    I'm sorry to be the bearer of sad news but, any decent plant can not be filtered with a PC fan as you show! My 5" Rhino pro would fail with that fan....!

    However, I am the eternal optimist Show me the fully grown plants rather than some pots & I'll merrily discuss things more

    What COBs are you using?

    Oh man how the heck did you manage to cool that thing? The first box I built had a 400W HPS too, I had to duct the air in and out only for the light not to have a sauna for the poor plants.
    By the way the box is not that small, its a 2m high cabinet, 80cm wide , 60cm deep. I just use huge 30 liter hempy buckets, thats why it might seem small.

    I have a 250w HPS in that space 400w is easily doable... but would grow me more weed than I need, hence the 250w

    have to agree with M_C there... no way that pc fan an diy CF would be sufficient enough to remove the stink or heat from a decent light... i had rvk 5” L1 on mine LOL would put a pic up of the plant but sure everyone is sick of the sight of that thing by now 😂

    These are my babies now: Amnesia XXL Autoflower, Day 51. The smell really hits when I open the doors.

    I use Citizen CLU048-1212C4 LEDs, 10 of them. I drive them with 700mA drivers , so heat is not an issue. Maximum temperature with a 22 degree room is 31 C.
    I got an infragun just to measure the temps:

    If you can have your COBs that close then, with all due respect to your setup, you have some major problems going on.... just sayin'...
