Just saw this thread and wanted to follow along. The 4x Vero 13s in my PC are working a treat, can't wait to see what you end up with.
whats the total wattage? oh 40 watts , lil low?
and give em sum water eh
Looks like they are a little low on nitrogen, and have some issues and need abit of water.
But that's more than enough light for that space , 5000-8000 lumens per sqft depending on the bin of the chip, Should be fine for some nice yields.
Sure the odd issue should be worked out and maybe a fresh coat of some flat pure white paint, but nothing that can't be done easily.
Chloemobile i'll be watching for the next update
1000 (dissipation W) * .36 (HPS efficiency average over 12-18 mnths) = 360 PAR W
Apply 20% reflector losses (288 PAR W) and 10% glass losses (260 PAR W)
260 PAR W/16 ft² = 16.2 PAR W/ft²
16.2 * 10.7 (ft² in 1 m²) = 173 PAR W/m²
173 * 4.98 (umol/PAR W for HPS) = 863 PPFD
