New Grower Danielsaaan’s Second Grow

[Delps8]

To those using Photone or something similar that need a diffuser over the cam — will any piece of white paper work? I have printer paper, just making sure that will suffice and give me accurate readings…
Thank you!

Per the docs, the diffuser should be made from 22 pound paper which is "standard" Office Max issue paper. The diffuser is not required for Android.

Put Photone to work. At ~24” at 75%, they were getting ~530 PAR, which I realize is probably too much in seedling stage. Dimmed the light to right around 50%, and they’re now just over 300. Will keep it there for a bit. At what point do you consider upping the brightness?
Btw, awesome app!

Thanks all!

PAR ("photosynthetically active radiation") refers to the wavelengths of light that plants use for photosynthesis. PPFD ("photosynthetic photon flux density") is the amount of photons hitting an area over time (how fast it's raining) and it's measured in micromols (µmols) per square meter per second. Daily light integral ("DLI") is how many photons have hit today (how much rain did we. get). DLI is measured in mols.

To start, I'd go with the manufacturers recommended light levels. 530µmols for 18 hours is a DLI of 34 and that's a lot for a seedling. 300 will get you a DLI of 19 and that's a good starting point.

Cannabis will handle lots of light very early. Snag a copy of Photone and try to calibrate it back to your current light. Once they're happy at 530 µmols (that's a DLI of 34 mols) there's no reason to not aggressively increase the light level as long as the other components of the grow environment are up to snuff. Bugbee talks about going from 400 to 1200 in two days (that's with CO2). The trick is to use Photone to get you in the ballpark and then watch the plants to see how they react.

Day 44: Rotated the pots. Will need to feed tomorrow after work. Doing alright!

Looking good man! They are filling in nicely despite your issues early on with them.

Thanks Dank. Hoping they finish within the next month or so!

Day 48: Rotated the pots. Will have to water tomorrow I think. Will probably do some light defol as well.
