Hi, can anyone recommend a good organic soil mix in the UK? I'm looking at alpha mix and that looks good but I have some questions. All advice will be appreciated. 1)Is this soil "hot"? I want to first grow my seeds to about 8/9inches in a small greenhouse before moving them into the ground but I'm worried they'll get nute burn. 2) What should I add to this soil to make it better? 3) I'm not planning on adding anything artificial to this soil, so from when I move my plants into the ground, will they be ok in this soil right through to harvest? If so how much soil will I need for one plants whole life cycle. If not, what can I add to change this. Again, any answers or advice is appreciated.
