hey everyone!! im planning to grow a single plant in a 20 litre bucket, now my question is---> will my air pump that is good for up to 60 litres be overkill, ???? or am i good with that???
Roots end state grow medium is the water, once the roots reach the water, the other grow medium (hydroton, rockwool, etc...) becomes more or less useless. The air pump and airstones oxygenate the water culture allowing the plant to breath like it was in dirt, but only get the nutes you put in the water.
Unless you have a great deal of experience with miracle gro,which I'm assuming you don't from your question, It would'nt be wise to try to use it. Get some quality organic hydro nutes,they are alot more forgiving .I'ts very east to over fert with MG........hope this helps
