1.20.2024: Time to gives this a go. 2.3x2.3 tent, XS1500 light, 2 gal fabric pots. Pots filled with FFOF(90%) & Perlite(10%.) Don't ask me why I chose 90/10. Nutrents are the FF Trio. Also growing a freebee seed from Humboldt Seed Co(Emerald Fire OG Auto.) Decided to germinate directly into the medium. Light is at 50% power at 2.5ft from the top of the pot(s). I'll have the light running 24hrs until it sprouts(fingers crossed it does.) I sprayed the top soil with pH 6.5 water when i stuck the seeds in then placed clear plastic cups over the seed location. My 4inch fan is on the way and it comes with a monitor for temp and humidity....no idea what current stats are. Just hope the damn thing spouts. Fingers crossed. More to come.
1.23.2024: 3 days and still no sprout. Going to give it another day or two before i go fishing for them. Off to a fantastic start!
1.24.2024: They've finally popped....aaaaannnddd we're off!
1.25.2024: Took the lil domes off, opened 2/3 vents for some circulation. Been misting the top soil just to keep it moist with 6.5ph water. I also "bottom fed" 12oz of water just to keep things lubricated. On the fence about when to give the plants a proper watering. Might keep things going "as is" for the next two days. Inline fan and associated hygrometer comes tomorrow(1.26) so i'll finally have an idea on what the current stats are in the tent. Will make adjustments at that point in time. Light is 2.5 ft from soil at 50%.
1.26.2024: Inline fan came yesterday. Only set up the probe just to understand temp and humidity. With the light at 50%, 2 ft from the soil, all vents closed except one(1) port at the top, my current temp hovers around 79 and the RH is 50%. After setting up a humidifier, i'm now running 75 degrees, 64% RH and VPD .58. All within tolerance. I can already tell it will be a delicate dance managing heat, exhaust fan speed and humidity. Still haven't given the plant more than 2 cups of water and i'm only watering when the soil is dry. Tomorrow(1.27) marks 1 week since the seed was dropped. Plan is to lightly water the entire pot when dry for the next week or until growth really kicks in.
@Heretic, i'm shooting from the hip here but i'd guess somewhere in the 375-450 range. At the time of this response, i'm at 12 inches from top of the plant at 50% power or 75 watts. if you check the light's specs, 50% power at 12 inches should be somewhere in the 400 ppfd range.
I really appreciate your grow diary!! I'm on first grow and alos using the xs1500pro and everything was great but I also notcied the white tips around week 4/5. I've searched high and low for other users with this light. Right now I have it at top of the tent on 100% so about 30 inches away from tallest plant. I did have it about 18 inches on 80% but definitely had some light stress going on. I would like to run a couple few plants at different stages so that is why I'm testing the light where it is. I've noticed several users of this light reporting white or yellow tips on top growth. I'm also running 20/4
