Whao! That shit looks fuckin pimp! The Metal halide "sure-on" feature looks like it will definitely do the trick. Gonna have to save up some cash and upgrade. Thx for the info!

Interesting. I have sun systems harvest pro 600 remote ballasts.

Thx desertrat. My digital timer does have a battery backup (it stays programmed when unplugged) but didn't turn the lights back on. sound like I'm going analog. Thx!

A little help for a fellow grower? Anyone?

It really depends on the amps of the mini split and the dehu. I have a 14K btu dual hose portable AC which runs around 12 amps, a 10" max fan, a sentinel CO2 regulator, and a 8" vortex fan plugged into my CHHC-1 and it handles all of those just fine. The CHHC has a light sensor so CO2 is only...

Any ideas?

Thanks for the input Mcgician. Actually the timers all work normally, as they did before the brown out. They are all turning on the lights, pumps, etc. at the set times and turning things off at the set times. I believe they would have turned on at the next set time on interval had i not done...

I'm using a hyrdofarm digital timer to control my lights http://www.hydrofarm.com/pb_detail.php?itemid=4168 There was a brown out (where the power goes off for just a second) in my area yesterday. When i checked my grow the lights were off and they didn't come back on afterwards. I immediately...

I would spray and turn the lights out for an hour maybe two (check the leaves to see if they are dry) and then back to 24/7.

I did calibrate mine before using it. 776 for a closed room does seem high. I would calibrate and test again.

Mine works great for my setup. Please keep in mind though that my room is not a "sealed room" in the strictest sense of the term. When the night temps started to drop in the fall I added and intake and exhaust for the room and put a temp sensor on the intake so that when the CHHC-1 kicks on...

Yes. My computer is always on anyway and my home office is right next to my grow room so i have a 25' cable that connects.

I haven't been checkin it but I will if you post something :)

The data is live only so it starts recording when you start the software. The autosave works only the first time and then craps out which also sucks. Hopefully we'll get a working version soon. No worries. Thx for thinkin of it!

The CTL tab on the upper right will allow you to set a parameter (though I haven't tried it to be honest.)

Along with the data dump you can also set parameters like temp and PPM. It's very rudimentary at this point and the autosave feature doesn't work but hopefully it'll get better. Attached is a screen shot of the software and the data output. Since we can get data on the computer hopefully we...

Thanks for the info and the support Bob. I've learned not to argue with anyone on RIU. If they are even remotely intelligent they will do the research and/or the testing to verify info for themselves. P.S. "He" would be the correct pronoun.

The required cable is an RS232 cable. You probably wouldn't have on lying around. The end of it looks like a VGA monitor cable but it is probably different. I bought mine at a local computer store. It looks like this: http://www.cablestogo.com/product.asp?cat_id=919&sku=25216 Both ends are...

Yes, you have to decompress it using a archive utility like WinRAR or WinZip. http://www.rarlab.com/download.htm

In case anyone is interested I found some software that will capture readings from the CHHC-1 and exports the data to an Excel spreadsheet. The software install is in Chinese or Japanese but just press the "next" button and it installs fine on Windows XP. The program itself is in English...
