MrStinkyanswered grow question 3 years ago I'm currently using the RQS nutrients, veg / bloom boosters, fungus and root bacteria.
They seem SO much easier than the Green House range, I did look at those and bio tabs too but decided for RWS Easy Boost. If you didnt but greenhouse yet try RQS man.
I am not dissapointed, I am probably a lifetime customer (until I can make my own super soil). Check my current RQS diary if you want man - my germination week shows how I mixed it all together.
No regrets with RQS nutrients.
