Has anybody tried or seen Hydro Innovations (made by surna i think) new 450ppd commercial dehumidifier? Thinking about picking it up but thought id see if anybody has any experience with it. It is also one of the few I've seen that is 240V.

Grow stones since day one for me. Just make sure you rinse them before use. I also soak them for 24hrs in ph'd water.

Thanks TK, ill post again once I'm in the building. Metal beams are not exposed.

No pics yet, current tenant is moving out at the moment, should be in the unit in the next 2-3 weeks, just trying to prepare. Yes it will need to be inspected before our license is given.

Been awhile since I've been on here, ran into some delays in getting my rec. license in Washington. But looks like we are back on track and close to starting our build out in our new warehouse. So my question is, what's the best way to hang grow lights in a commercial warehouse with 18ft tall...

My tap comes out at 200ppm. I use a simple RV carbon water filter ($25 at home depot) with no problems.

Dont sweat your ph swing, whether it be UP or DOWN. if you have health roots and health leaves you have a health plant regardless of your ph swing. a page back i responded to your ph swing and still find that holds true. i to am on week 4 and experience the same exact thing. your downward...

great idea and looks like it works great! I kept it simple, added carpet padding to up sized ducting (6" fan to 8" ducting, 8" fan 10" ducting, etc. but can go bigger if needed but doubt you will need to) took carpet padding and rolled it around the inside of solid 5' ducting after the fan. Used...

I have found that in general, with the CS Booster the ph Drops, and with Bloom A/B the ph Raises.

In my (limited) experience i have found that as the plants use up the CS base nutes the ph raises. But as they use up the CS Booster the ph drops(Water consumption stays the same regardless of ph changing up or down). these results so far have been consistent over multiple res changes and many...

I've been adding 1/32 teaspoon of 99% iba to about 100 gallons UC (12 site 8 gal.)system once per week during veg. Not really sure if that's enough or even frequent enough. Anybody have any ideas, other rates of application or personal experience with this?

Amen lol

Good God!

Well put, Thanks for your input Q9

I am having the exact same problems right now and have yet to figure it out. contacted cch2o a few times and am getting contradicting suggestions (ppm to high, then ppm to low etc.) Curious if we can find a answer for this one. This problem doesn't seem to not follow the rules lol. I don't know...

i have bulkheads on mine and had a few leaks coming from the buckets. i re tightened them once water was in the system. i still had a few minor leaks but once the water warmed up, all the leaks went away (my tap comes out at 42 degrees). really cold water can make the rubber constrict and not...

Most likely that's just how they are made, as most fans are made pretty cheap (even high end fans), and not necessarily air tight. I have a few different brands of fans, but a couple of my fans had slight air leaks at the seams. I consider this normal now that i have seen it a few times with...

I put HVAC (foil) tape over the seems, worked for me. Shouldn't be enough air escaping to cause concern though.
