*You can measure this with a lux meter and convert the reading into PPFD.* This is not ideal, Lux to PPFD is not a simple conversion and depends a lot on the specific LED's diodes and spectrum of the light. even the online tools use a flat conversion rate that does not equal what it really is. more of a ball park and they can be very off. Especially if they are old school bluepule LED's They will register 150-200 on a lux meter and be over 1,000 PPF on a quantum par sensor. factor in the convention to PPFD by your grow area and you can be upwards of 1500-2000 PPFD in smaller tents. D=Density and that needs an area of space to calculate.

1500ppm anything more and the plants will struggle This is totally wrong. The plants need CO2 and humans need oxygen. Keep below 1500 ppm , which is enough for any plant. Above 5000 ppmit will get dangerous for humans.

So you used table sugar?

Yeah...I'm not a fan of this article. Sounds like it came from someone who doesn't even smoke.

Nice and frosty! 😎
