Hi @karsten74! Well, any veg fertilizer of your choice with a decent amount of Nitrogen will do the job. Biobizz has a great products line, if you're looking for organic fertilizers. However they do have some downsides: you can't keep them more than a few months, they tend to smell (in the bottles+in your soil), and they're probably not as much efficient as some other non-organic fertilizers. I'm now using MegaCrop (it comes in powder), I have to say I think I'll never go back to liquid fertilizers again, powder is easier to use, balance, and store. If you don't want to think about feeding schedules and nutrient intakes, you can take an all-in-one solution such as BioTabs or GrowCaps, these products need to be mixed in your medium then you only add water. Hope this will help, keeps us up-to-date, and happy growing! 👊
