1.27.2024: First week in the books. Today marks the first full watering i've given the plant. 6-8 cups in total of 6.5ph tap water that. Surprised to see 2 cups worth of runoff. Tested the runoff, 6.5ph. I think thats good? Still under 24/0 light. Will set up a timer and shift to 18/6. Biggest issue is controlling humidity. Monitor was reading 47% so i bought a small humidifier. Very difficult right now to control airflow and humidity. Can't have a fan on with vents open while the humidifier is going cause it just blows out. Even with a bottom vent open and a top or side vent open, humidity can't stay above 60%. If i close everything the humidity shoots up to 80% and looks like a jungle inside the tent. I've got a 4inch inline fan waiting to be installed but it will literally suck the life out of the tent, so no use for it right now. Plant is just over 2 inches, and while they have great color and look strong, they just seem tiny for day 7. Hopefully i'll see better leaf production in the next few days.
1.28.2024: Installed the inline fan and carbon filter. Have the ducting going into the top of the tent and the fan/filter outside pulling the air out. Temp is 78, RH is 66% and VPD is .9. Right about where the chart says it should be. I watered till run off yesterday and ph is right in line too. Won't water again until the soil is dry and the pot is light.
1.29.2024: Nothing much doing today. Temp's holding steady at 77(f) and humidity is 65%. Soil is drying up but still moist in the area immediately around the root. Leaf(s) are getting bigger and i can see new formations coming but not too much in vertical growth. Steady as she goes.
1.30.2024: Temp and RH same as yesterday. Still have the lights on 24/0. Moved the light down to 20 inches from soil. Still at 50% power, 75 watts. Top soil is mostly dry but probing below surface there's still moisture. Perhaps i'll water tomorrow? Nervous about shifting lights to 18/6 as i'm not sure how that will affect tent conditions i.e. temp, RH and ventilation.
1.31.2024: Plant spent first "night' under 18/6 lighting. Temp help at 71 and RH dropped to 47% due to the humidifier being turned off. Watered with 4 cups at 6.5ph. Dropped light again to 18 inches from top of soil. Might go lower. I'll add pics soon.
2.1.2024: Steady as she goes.
2.2.2024: Steady again. Temp and RH holding at 77 & 62%. Light is 12 inches from soil at 50% power or 75 watts. Have my humidifier on a timer concurrent with the light.
When off, RH drops to 50%-47%. I monitor my inline fan speed from the app and look to adjust as needed. Tomorrow marks the start of week 3. Plant is still getting all nutes from original soil. Won't feed until they *start* showing signs of needing it. Perhaps i'll be more proactive as we get closer to week 4.
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
@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.
