Budget-Friendly Smart Grow Tent Upgrades: Irrigation, Sensors & Automation?Hi! I have a carbon filter, 221 m³/h extractor and a full setup. For 1–2 pots, I’d love cheap smart irrigation with an app and moisture sensor that waters only when needed. Any other affordable sensors/gadgets to monitor cannabis, soil and tent? Easy DIY or ready-made? Thanks!

Is Everything Going Well So Far?Hi everyone! My little plant sprouted on September 10th, and today is September 22nd. Do you think it has a good height, size, and, most importantly, good internodal spacing for its age? Does it look okay to you? biobizz lightmix, sf1000 40cm 60% dimmer

Early Growth Check: Tiny Leaf Spot & Internode Spacing Hi everyone! Is my plant okay? I noticed a tiny spot on the new leaves. It’s 7 days from sprout, growing in BioBizz Light Mix, and I’m only giving pH-adjusted water, no nutrients. Could it be low CalMag, or am I overthinking? Is the light distance and internode spacing okay?

Spider Farmer 100W: 45cm / 60% too much for a 4-day-old seedling?Spider Farmer 100W at 45cm, ~60% dimmer. At 35–50% and higher distance, my seedling stretched ~5cm in 2 days. It’s now 4 days old. Biobizz Light Mix, no additives, RH 66–70%. Should I keep 45cm/~60% or raise/lower intensity?

Harvest day is approaching... tips to avoid ruining the flavor and potency ❤️I'm entering week 8 in 2 days. I was wondering when this Nicole Kush will be ready. And above all, how can I ensure that the flavor and potency are preserved perfectly, considering that my room is 20/22 degrees. Lens video trichomes https://jumpshare.com/s/ic44B8XenEdbd7Q2xWSw

Why doesn't it show any deficiencies? While my autoflowering plants in the same conditions immediately turn yellow?Guys, quick question: how is it possible that this plant, at week 5 (switched to flower just a few days ago), grown in Light Mix, was fertilized only one week ago with ADV at 1 ml/L and then nothing else, yet it shows no deficiencies at all? How is that possible in Light Mix?
