Attempting to tune 'automation', pinset not forming/aborting?
    #27064376 - 11/30/20 11:11 AM (3 years, 1 month ago)

So I've been working on trying to get some automation going in my grow area, I'm unable to provide FAE 3x+ a day at even intervals due to my work schedule, and I believe that's a main issue for me. My tubs are unmodified, and I've had great flushes with them in the past. As I've increased the amount I'm growing however, I've noticed that my flushes are becoming more sparse, and my pinsets are aborting much more. I'm not sure if that's from environmental factors, or possibly senescence. I've been working with a sporeless B+ isolate, and I've done 11 g2g transfers with it that I use for spawn (each time I make grains, I set aside one of my jars that I've transferred to for the next batch of jars, and now I've done this 11 times). As far as the environmental factors, I thought maybe it was due to CO2 build up, so I got a CO2 meter, and I'm finding that in my immediate grow area my CO2 gets up to ~3500ppm. I've got a large HEPA filter that runs to my grow area that I have turn on twice a day to push out the CO2, which drops the ambient CO2 to ~1000ppm. My humidity in the grow area is around 40-45%, and my temperatures hang around 78-80*F during the day, dipping to 74-76*F at night.

Any advice here? My ideas so far are to cycle the air in the grow area more often, either continuously throughout the day (short cycles repeatedly to achieve a lower CO2 level all day) or just more often so CO2 is low at different times of the day. My other idea is to deal with possible senescence, and to clone a fruit from one of the currently fruiting tubs and to restart the isolation (I've already started this).

Any advice on this would be appreciated, trying to get things working smoothly is always difficult when only working with one view point, and in this hobby it can be difficult to get more view points!

Bit of a bump here before I split this into other threads to ask about senescence and general FAE schedules :laugh:

So I did some more tuning with my automation, just posting here for anyone searching in the future.

I got a better timer hooked up to my blower that pushes air into my grow area, and now every 16 minutes the blower blows air for 4 minutes (3x an hour, 24 hours a day), which is enough to equalize the grow area's CO2 ppm with the CO2ppm outside of the grow area (~700ppm, not super healthy, but not in a bad range either). Since then, I've got a few tubs that are putting out much nicer, more even flushes. They're looking a bit long with small caps though, so I think I might need to increase the air exchanges a bit, maybe do 4 minutes of air exchange every 11 minutes (4x an hour, 24 hours a day). Anyway here's a picture since I got my premium account back :laugh:
