Green house feeding

Hi mate, I use their bio line and have done since i started growing. I absolutely love it. Yes it is a bit more expensive than more popular nutrients but you can't put a price on quality. I've used it in all my grows, I don't add any other additives apart from whats in the bio line. Including the Bio Enhancer. Any issues I've had with my grows have been my fault due to inexperience. They do a starter kit now, I'll be honest and say I got mine free as part of a contest last year and still have loads left for many grows. Definitely goes a long way, Highly recommended 100%. Good luck

Not sure, but always take concentration into account. A highly concentrated nutrient may be cheaper in the long run even though it's pricier at face value.
