Noob Question On Soil i bought

Just went and bought a bag of sea soil which looked pretty good for growing since i cant get roots 707 or fox farm ocean soil in canada. do you think there enough nutrients for the first week or more? thanks very much.

Looks ok to me I would prolly give it a go and just pay attention to how the plants look and add fertilizer as needed, depending on pot size you should be ok for 1st month at least unless using really small container. Also prolly a good idea to become familiar with their FAQ page http://www.seasoil.com/faq.html looks like they have a clue on their product. Good luck I would think that your not gonna have issues with it from what they say on their site but you never know till you try^^
