If you haven't grown before, I would recommend using peat first to get the feeds and pH down right. Peat is a soil-less and very forgiving for beginning growers. General Hydroponics nutrients are also good for learners. If you have a little experience then Grodan rockwool is another good media for new comers. After you've master these two then you are ready for the liquid hydro and can do:
- Wick Systems.
- Deep Water Culture (DWC)
- Nutrient Film Technique (NFT).
- Ebb and Flow (Flood and Drain)
- Aeroponics.
- Drip Systems.
Was it high N switcher? A few have commented there nova range carries too much. 4% by the bottle, but the feed chart indicates 8%. That's a 100% margin of error. I can't work like that.
Ionic is a decent single bottle solution. No feed is everybody's favourite, but I never see any haters. Which is worth a lot.
