I like that the tent holds its own with just lights on for room temp and the insulation keeps it from getting to cold temp set at 63 for heater. This is an un heated attic area
Wicked. Right now I just have a heater turn on every couple of hours. Maybe a controller would be a good investment next season. Hmm…
Nice haircuts, looking good brother! 
So my heater has its own Thermostat but its to much of a swing were the inkbird i think regulates on a different Thermostat and doesnt need to run as much. Set at 63 hardly ever comes on. I use one for cooling and then the heat lung room fhas its own to bring in fresh if needed. I use a device that tells me whats doing what on the electric draw. The most space heaters draws more than my lights. Found a small heater at walmart runs around 300-400 watts much more betterer .lol
Love my inkbirds.
Afternoon Cultivators,

Does not convert to DLI. 
I used to push 60 DLI in flower which I think was 1200-1400 ppfd… which confuses me. I will be doing some tests with numbers while I run off off ppfd.

I think my heater for the room is around 20-25 years old. Lol. I have small smart heaters but they aren’t so smart anymore inset it for 75 and they won’t stop til it’s 90.
DLI is simply a calculation based on the amount of hours per day of light times the PPFD, so it is a fairly easy calculation, and I just wondered if the meter did it directly.
A bit (too much?) about the subject:
Once you have a value for PPFD, the DLI is just the daily photon dose per unit area. The units of DLI are mol/m2-day.
A two-step process is recommended, first convert the PPFD to mol/m2-hour, then calculate the number of hours needed to achieve a desired DLI dose.
Continuing our example, the nominal PPFD from above is 150 μmol/s-m2 and the unit conversion factor (0.0036) gives 0.54 mol/m2-hr. This implies that 150 μmol/s-m2 has a maximum DLI of 12.96 mol/m2-day. Published data for optimum DLI for various types of plants tend to go up to 30 mol/m2-day so we may want to iterate the PPFD design calculation with a higher target.
A DLI of 30 with 20 hours on-time requires a PPFD of about 450 μmol/s-m2. It is an interesting coincidence that the lux level design goals for lighting an office space have similar numbers as optimal PPFD goals for horticulture lighting.
Thanks @Newt 
i was just planning to use this if I need to
I will be upping ppfd to about 600 today heading towards 750 over the next few days.
Great tool @Low ! 
And don’t forget… … 
Here’s the website for people following this discussion…
Edit…: Oups my bad…
But I’m pretty sure this link is good…
What do you say @Covertgrower?
My bad, I tought you posted this elsewhere… 
Hopefully it’s ok. Just makes things easier.
It might be okay. I posted often some THC calculators for edibles… We’ll find out soon I guess!
