just a quick question please, when your growing cannabis plants in hydroponics and the plant gets bigger........the roots get longer.........once the roots get so long and they hit the water at the bottom of the hydroponic, won't the plant drown bcoz of 2 much water intake?
thanks.
any1?
??????????
You place this in the Lounge part of the forum. It should be in the Hydroponics part of the Cultivation forum. I moved it for you now you should be able go get your answer.
thanks
now im a little confused, i read that plants like oxygen.........but sudnt b in water 4 2 long. so if i have a air-stone in my hydroponic set-up, can i leave the roots submerged as long as i want?
If you speak about DWC systems the answer is not at all, because the water is full of oxygen, because of the air stone. If you cut the air flow, they will drown, for sure. That's it. In one of my buckets, the air stone get out off the tube, and now it's giving big bubbles with a very funny noise. But it's still OK, the roots are very big now and will soon fill the bucket, drink 2 liters a day

sweet dude thanks alot much appriciated :). by the way i suppose u dont know a UK website which sells rockwool, i bought the wrong stuff :S
You supposed right, i don't know, i'm not from UK. You should find that in any big town, i think. Bubbler is a very good system, the only problem i have is to give enough air to these plants, air pomp are not so cheap...

..........is HPS light bulbs expensive to run in electricity?
You can even trim the lower roots tips back too if you need to.
