I’m a bit concerned about temps though. I’ve got a 600W HPS about 60cm from the canopy, and I’ve intentionally put it higher than I might have wanted to kinda break them in to the new light after transplanting.
I’ve got two thermometers at the canopy - one standalone digital, and the probe for my Sonoff TH10 which controls my tube heater. You can just about see them both in my previous post. They both suggest it’s kinda high there already, although they differ in their readings by a few degC. The Sonoff says 28-29, and the standalone says 25-26 The Sonoff also reads humidity about 8-10% higher. I’ve been working off the standalone unit so far, and everything’s been fine, so maybe the Sonoff’s over-sensitive. It is just one cheap Chinese product vs another though…
I’ve turned my vent fan up to full power (happily had it running at half pace throughout veg)
I guess it’s just a case of keeping an eye on it. I’m not sure what more I can do, maybe another circulation fan over the canopy? I have a feeling it’s gonna be a challenge to keep them safe from burning as they grow upwards. Should be fun…
