I went to my local garden center and asked them if they had any soil suitable for my first grow i.e npk ratio 20-10-10 or 10-7-5 with no added fert or moisture controle and they told me i would have to have it specificaly made ? while i was looking around in there i come across this soil that is made for expecialy for seeds and young plants and it had a very low consentration of organic fert so it wouldent burn the young plants,would this be ok or not ?
