...Here is the "Pulse" environmental chart for the germ. period. I started tweaking the environmental settings until i got to where i am right now. This is "ideal range for germ. " according to "Growing Elite Marijuana"
The Pulse (yes, the "thingy" advertised on the right).
If you don't know what it is; you should. read this thread ==> Pulse One Hygrometer & VPD Monitor
I love mine as i stated in my original comment on the product (Here) ... "I picked up two of them over the last couple of weeks as well, and will be buying a third on payday. One for each cabinet and one for the room itself. I love the info provided they seem to be well worth the $$. Now we see how long they last.
I have dialed in the grow closet and i'm working on the flower closet now. As someone else mentioned, i was close (in the yellow portion of the curve chart). However i can see what would have been the difference had i been in the green zone during more of the grow.
Will be using it more for this next grow, if i can get the damn seeds to pop.
Here are my current environmental settings. DDRE=Grow/Germ Cabinet; Biggie=Flower; Tupac=RO res/grow room. I still need a new humidifier for "biggie" but i have a few weeks before it is needed again.
I have kept "biggie" running and keep adding replacement RO to keep it going. I have not noticed and degradation of the res. I did take the time to turn everything off for an hour or so and pull all of the remaining root material and rocks out of the bottom. I also took a small pump with a piece of surgical tubing attached and "vacuumed" out the gunk that had settled to the bottom. Temps & PH have been maintained.
After my babies pop, i will be taking the VPD on DDRE to .8 or .7 still doing research on the proper setting for flower cabinet.
