8/10 Monday. 12:05AM FULL RETARD MODE ACTIVATED
8/10 MOnday - looking good needs water will ask Grok: For your Fast Buds autos (RF3s + Mendo Frost) at roughly week 5 in coco, target an incoming EC of about 1.2â1.6 mS/cm (roughly 600â800 ppm on the 500 scale).
8/11 4:30am 550 PPFD is solid for where those plants appear to be.
Looking at the photo, youâve got a clean, well-organized Spider Farmer tent with healthy-looking plants in fabric pots (plus the smaller one in the white pot). At 45 W per light (90 W total) and hitting ~550 Âľmol/m²/s, the efficiency is actually pretty good â modern diodes can deliver that intensity when the lights are relatively close and the footprint isnât oversized.
Quick context for that PPFD
⢠Current stage (looks like mid-to-late veg on most of them): 450â650 is a strong sweet spot. Youâre right in the middle.
⢠You can push a bit higher (600â700+) if you want denser branching and tighter internodes, but 550 is already productive and lower-stress.
⢠Once you flip to flower youâll generally want to climb toward 700â900+ (depending on how the plants respond and whether you add COâ).
A few practical notes
⢠Height & uniformity: At only 90 W total, the distance from the canopy is doing a lot of the work. If the outer edges or lower plants are noticeably dimmer, you may need a slight height adjustment or to rotate pots so everything stays even.
⢠Heat: 76 °F and 48 % RH is comfortable. With only 90 W youâre not fighting heat.
⢠Dimming headroom.
The plants look happy â good color, no obvious light stress or stretch. Youâre in a good place. If you want to share the exact model of the lights or the tent size, I can give more specific height/PPFD targets.
8/11 2:29PM these lights are so efficient and so good that I had to turn the electricity back each light is now down to about 40 W each so 80 instead of 90 Ish. I didnât check the PPFD rating so I donât know what the light measurements actually are, but I know keeping them at 40 each so a total of 80 W is very good. I raised the lights out there about 12 inches maybe a little bit more about 14 inches high off the top of the plant but doing good so far my EC was 1004 on whatever scale that is Iâm using from 900 to 1.2 is what was recommended for EC.
