Using Prefertilized (pre-nuted) Soil

Hi I am a newbie with a quick question to the advanced and moderate growers, even other newbies any input helps. When using a prefertilized or prenuted soil like Miracle gro or Schultz, that come with fertilizer already added.

Do you need to fertilize or add any other nutrients thoughtout the whole process. Because they claim they feed for 3-4 months which is pretty much the whole growth process for most strains.

Also since these feed so long, if you only grow for 2 months which means all the fert in the soil is not used up. Can these soils even be flused to prepare for harvest, or is it not possible.

Also at the time of harvest with all the residual Fertiziler that will be left in the soil if flusing is not possible will the affect the smoke and taste of the finished product. I have heard that too much Ferts in your finised products will lead to a harsh smoke and a metalic taste.

Any imput from anyone will help To anyone that have used these types of soil to harvest. What are your opinions on the burning quality of the finised product.

I have searched this site for days with my problem but no answer if there is a thread or post on the issue already sorry for the repost, and can you please provide me with a link to those threads.

Yes to every single question, except if you should use it. In that case I would say no

You will need to add more nutes, becuase cannabis needs different levels of nutrients throughout the grow process. More nitrogen in vegging, more phosphorus in flowering.

You will get chemicals in your bud, and it will taste harsh, and not good.

Get something with no added fertilizers. If you can only go to walmart, they have Miracle Grow Oragnic, that will do just fine.


I feel like I have already answered this question tho.... humm

goodluck <3

i would have to aggree that pre fert soil is harder to control the levels of the nutes. start from sratch and add what you want.

Ive been using Scotts soiless prefertilized soil. The nutes seem to last about 3 or 4 weeks before they need nitrogen. The problem with the prefertilized soil is it will burn clones and young seedlings.

Thank you all for the input any more will be more than welcome.
