These lower leaves are dieing off. The lower large leaves apear to go brown at the edges and then rot away. The new (lower ) growth that doesn't get much light also has similar problems. Some of these shoots also may wilt. However the plant doesn't drop these leaves. Even if you pull them off...

As the title says, plants are perfectly healthy, until you touch them... Seriously like just gently inspect them for bugs or whatever, or simply rotate them ( for better light coverage ). They INSTANTLY (as in less than 10 seconds ) wilt right before your eyes ( only the stems ), the leaves are...

400W hps , Canna aqua , ph 5.7 - 5.9 ( checked daily ) temp 68-78f What would cause leaves to fall , in a aeroponic system? It only started a few weeks into 12/12. Mainly the lower leaves - but even higher ones that look perfectly healthy and green are falling. As much as a handful every...

Just curious, is there any way to recycle all the runoff water ? Scenario : A large hydroponic grow room in a desert/dry , remote location where bringing fresh water is just about impossible. A R.O. machine would work, but they are not efficient , they waste a few gallons to only get a...

Smoked some crazy bud the other day. Made me feel like i was in a dream. My friends also had the same experience !! Won;t be able to get any more of this now :( We have only experienced skunk before really.... Any ideas what it could be? Would a haze sorta plant do this to you?

Anyone know what could be up with these plants? It appears they have good moisture, perfect PH and nutrients at the right level. Out of a garden of 10 healthy seedlings, these are the only 2 that have the problem.

As the title says. My friends plants are 2 inches tall - 3 weeks old !!! The humidity is realy low, but i didnt think this would cause a problem , provided the plants receive enough water to their roots?

400w in an homebox xs (2 x 2 ft) grow tent. Heat is not an issue , homebox will be in a cold room , with a serious exhaust fan. 400w / 4 square ft ( 2x2 ) = 100w per sq-ft 250w would be 62.5w per sq-ft I like the sound of 100w per sq foot but is 100w going to be a bad idea ( too much...

Just as the title , Should a carbon flter get rid of 100% smell ? Or will it need to be supplemented by an ozone generator etc?

My question mainly comes to the point of electricity consumption. For example two seperate rooms: NON autoflowering strain 12/12 1000w hps Autoflowering strain on 24/0 500w hps Obviously both rooms will be using the same amount of electricity every month, but won't the NON autoflower strain...

Is there any ( growth / yield ) difference from using different shaped pots? Sure weed likes deep pots, but im talking the shape of the sides, ie : round or square. I'm sure that you could fit slightly more square pots into a smaller space, but other than that are there pro's / con's about...

It looks like these 3 plants are either mainly male hermie or totally male. Damn. Agreed?

Water has always been PH'd to 6.0 , and the runoff used to be 6.0. However didn't check the runoff for a while and now the runoff ph is between 4.3 and 4.5. The coco was flushed with many gallons of clean fresh ph'd water , and still the runoff ph stays at 4.5 !! Is there a serious nutrient...

Found about ten decomposing oak leaves in a bag of canna coco plus. Is this normal??! I thought coco was made from coconut near the coast, but thats an oak leaf? There were about 5 in scattered though the bag....
