I do not grow hydro so I shouldn't try and answer but some organics may decompose and cause problems in the hydro system. Wait for better answers though.
Shovelhandle Reviewed by Shovelhandle on . Is it ok to use organic fertiliser for hydro ? I have just transplanted 4 bushys from soil to perlite and wondering if its ok to use organic fertolisers such as seasol & powerfeed (liquid fert)- both Australian co's. these r the only nutrients I have worked with in the past and have had good results. But this will be my first grow indoors and am very new to everything. Cheers294268 Also I'm using a gravity feed tank/ aquapot Rating: 5
