Hey guys just wanted to make another post on another method of growing cannabis, which can allow you to have bigger yields, and grow stronger weed. Hydroponic systems are usually quite expensive to set up, how ever a single plant system can be set up with just a bucket and a cheap pump.

So to make this you can first get a large container with a lid some thing like this one below would be perfect, although if your wanting to do a micro grow then you can allows just use something smaller like a coffee tin. In a coffee tin the roots would not be able to grow as big this would result in smaller plant.

Next you will need some type of air pump, an aquarium oxygen pump will probably work great for this. These can be bought on Ebay and Amazon for around £7. When buying one it would probably be best to get one with long tubing which is able to reach down to the bottom of the bucket.
Heres a link to a cheap oxygen pump I found which would work great for this:

Next attach the pump to the side of the bucket, then drill a hole in the top of the bucket to put the pipe into the water. An oxygen pump is needed in a hydroponic grow to give oxygen to the roots of the plant, without this the roots would rot away.
Next you will need to acquire some Rockwool and a mesh pot, this is what you will be planting the seed into.

Next using a sharp knife cut a circular hole in the bucket/ coffee cans lid and insert the Mesh pot and Rockwool into the top of the container. Next all is left to do is plant out the seedling, put your nutrience of choice into the water, and turn on the pump. I would also like to add that this method of growing is best suited to growing indoors doors.
