I'd be interested in if the light raise helps. I am familiar with similar problems, but they are on the bottom leaves.
imgur: the simple image sharer Here are a few more with the HPS turned off. For some perspective they have all lost their biggest branches to a...
Another pic tomorrow. The Ph Meter is a calibrated Hannah Ph/EC/PPM meter. Not sure if you have to calibrate the EC, and it gives wild readings...
imgur: the simple image sharer Hey all. These plants are dying fast. All are light, light green to yellow and have lost all lower vegetation...
Great thread going guys. I bought a Hanna ph/ec/ppm meter and it works great. I don't yet know what that "u/s" in greek letters means but I'm...
If no one else is going to smell it, dont worry about it. But most likely you'll need it. It doesn't hurt.
Bump. I'm looking too!
I can't believe no one mentioned LST. You should really be bending stalks to get more light on the lower levels. This also brings the plant...
Close up pics of your options would be good. The crappy $6 Walmart ones have little to no chance of working correctly, just so you know.
A simple way to give weight to the differing opinions on here is to look at how many posts a person has. Fewer than a 1000 would be sketchy to...

Hope you didn't kill it. Spiders are good luck. I don't understand why people say do the "back of the hand" test when its a very rough estimate....
Yeah, your question is an old one. Put a reliable thermometer at the canopy level and adjust the height until the temp stays in the low-mid 70s....
Yeah, your buddy is right, just bend them...look up LBH's LST training sticky (main thread in the main page.)
I had the same thing happen...the mechs in Walmart didn't even TRY to work.... The $14 digi did, but then I still had to get a better one (15A...
Well, they're 240v first of all, so it sounds like you need a washer/dryer cord and outlet for it. I think the design wastes much of the light...
All of you talking about buying online, are you medical or legal geographically or in some other way?
