New to soil grow, here’s what I’ve got: WW auto and I have questions; I want to start the germinated seed w/a 1" tail in its forever home consisting of the following
5gall black bucket w/5 3/8" holes on bottom and 3 on the sides
5lb jade rock for succulents for drainage
12qt FFOF
HLG 350R Diablo light
clear plastic cup to dome the germed seed
What settings to use for this powerful light? currently at 16" hi and on #3 setting (#1 doesn’t illuminate)
FFOF says not to add nutes for 90 days. Can I use any/all of the nutes (diluted at first) I have from my attempt at DWC? cal mag, hydrogard, gen hydro floragrow and amor si’
Set the light at the distance from the canopy listed on hlgs website, then set the light to match these DLI settings depending on your grow week stage.
Thanks for the info! Sadly my phone is not capable of using the photone app. Can anyone recommend an inexpensive light meter (DLI?) for LED full spectrum light?
Cheapest quantum meter I can find. Works great. Accurate.
You can also use a lux meter… However, converting to ppfd is not as straight forward as lux and ppfd are different measurements of different things about light.
"Both PPFD and Lux are units used to measure the intensity of light. Whereas Lux is universally used to measure and compare the brightness of visible light, PPFD is referring to the amount of light suitable for active photosynthesis of plants. "
Good info, thank you! I found this one (same company) that appears to be the same as your link.
I am using a LED full spec. My questions is: I have a light chart for the entire growth., but it’s measured in DLI. How do I convert PPFD/LUX to DLI? Is there a light chart for PPFD/LUX?
