Noticed you had a bit of a slow start, Just out of interest, how much light were you giving them at the start? At three weeks I'd expect seven or eight developed nodes generally with lower nodes having two or three of their own nodes, but I have noticed a lot of people running lower intensities getting slower node progression.
I'm at day 16 ATM and pushing out the 7th node running 12/12 from seed, but have been giving 700umol/s from germ.
Hello, thank you for taking a look and commenting!
As seedlings they had 250-300umol/m^2/s, increased gradually up to 600 around transplanting time. They are still at 600, lights are 30" from canopy and intensity is set at ~65%, increasing ~5% a day as of yesterday.
I don't have a proper ppfd meter; I was using a phone app for little bit, photone, which is pretty nifty but perhaps not at all accurate. Screen has cracks so that definitely alters the light reading regardless of the apps accuracy.
I stopped using the phone app and I've been using a 3-in-1 pH/light/moisture meter to at least gauge the intensity, but I can't find from the manufacturer what units of measure their meter uses and I suspect it isn't ppfd, likely lux or something, either way this meter isn't a very accurate way to measure ppfd. It tends to show a little higher than the photone app.
Until I can afford a decent meter, I've been trying to go off how the plants look and being a beginner that has proved difficult, hah!
They did seem to be growing a little slow, but I was concerned because turning the light up seemed to be burning the tips, but that could have been unrelated and then I starved them for light. Would you agree they seemed a little stretchy as babies?
ps Your plants are looking beautiful and luscious!
Thanks again,
Take care!
