Hey all, I am new to the forum and new to growing. I have done allot of self research about growing and am also taking a botany class. In my botany class we have been experimenting with Ga3 and its aplication with bush bean plants. It works really well on the bush beans and so after allot of searching i found a water soluable GA3 powder containing 20% GA3. I have searched everywhere for sombody that has used GA3 on canibis plants and mostly come up with people using it to feminize seads and nobody that has used it for flowering, their where also allot of claims that it caused hermies. I have also found a spray that is made in the netherlands that says it is to be used 23 days into flowering (i think), or when the third node starts to flower. It is to be used again (I think) on the 43rd day of flowering. The company also makes a hydroponic version that is used in the res.

So my qeustion is, how, when, and what is the ppm, of the GA3 when I put it in my RES?????????
