I just did a montage of the setup and controls I have now - I think a lot of you are going to like my “Bath Tub Factory”.
Top left is a timer for my lights, I have a 1200W equivalent full par spectrum LED fixture, and a pair of LED Spotlights that will soon be replaced with 1520 lumen white LED “Bright Sticks” and I am looking over a couple of RED LED light “bulbs” to go in there also, timer is set to 18 hours now. I got tired of trying to be up at 6 to turn on the lights (and missing the timing on several occasions) and also staying up until midnight to turn them off.
Second from top on the left I have a three-way plant meter of the general kind for Light, PH, and Soil Moisture checking, and next to it is the Humidity Control for the Honeywell humidifier I have on a small shelf I made to go over the angled up end of the tub. Next to the humidifier is a small fan that is turned on by the controller at the same time so that the mist is well spread out in the enclosure.
I set humidity to 52.5%, and you can also see a thermometer at the opposite end in one of the buckets.
~ As you can see, except for watering, feeding, and measuring with the 3-way meter it’s completely automated now…
That last yellow bucket has the first and only sprout so far of Durban P. in it, the others are Jack Herer (FEM’d) so I think of them as Group-1 and Group-2
Now, this IS a first time grow. But I think I almost have it down at this point. The soil responsible for the deviations in the Group-1 plants has been identified and corrected.
Each of the Group-1 plants are in the middle of week six
ANYWAY, that being a standard meter - does it mean that it reads in umols?
