i put a seedling in a little pot and then stuck the roots out of the bottom and filled a vase up with water and put it the pot on top of the vase so the roots are in the water so is this considered hydro the plant is still growing like normal its bin like this for about 3 days
That's the most passive and ancient of all hydro techniques. The aztecs used to float rafts of plants on lake beds thousands of years ago. Now whether or not it will work to give you a good crop, who knows? Usually your water has to be at a pH around 5.6 for the roots to uptake nutes. there has to be s ufficient amount of nutes in the water, no alge that could kill the root system, etc......
