i’m already battling high rh and thats a concern for me. plus i’m guessing wood would release even more moisture. maybe. i have no possibility to set up blumats at this point so its gonna be hand watered and that may also prove hard when watering the back corners etc plus rh would spike most likely.The RH increase is likely if you top water. For example with my bed. I have 17" of soil depth with a 2-3" cypress mulch layer. When ever I top water a tea or the like, ambient RH spikes. It goes down faster as the mulches surface dries. But I also use blumats with the blusoak, and It was suggested to me in my grow thread, to bury the blusoak under the mulch. Since I did just that, I haven't had any spikes in RH from the blumats. Only when I top water. I think that even if your just using drip emitters instead of the blusoak, you'd have the same result with consistent RH. It's when you wet an area from the top you have all that surface area that's going to release moisture, not what's under the mulch.
Sorry for the delay in response, I stepped away to change litter box's.
since this is gonna be a custom made bed i can go deep as i want but i haven’t got enough cooked soil to fill evn 150 gals so i may just go with 20s for a couple of runs and cook some more soil on the side, prepare for a bed upgrade?
