A 3 part nutrient system, the Flora system advertises itself as suitable for all growing mediums. We've spent 6 months using the Flora Series so that we could review it for you, and here's what we found:

About GH Flora Series

GH Flora series isn't a new kid on the block, it's been tried and tested for over 40 years! First formulated in 1976, Flora Series is the original three-part hydroponic-based nutrient system.

Flora Series consists of three highly concentrated liquid nutrients - by using in different combinations, you can satisfy each plant's exact nutrient needs for every growth stage and environment.

  • FloraGro builds strong roots during a plant's vegetative stage.
  • FloraMicro is used during a plant's growth and bloom cycles.
  • FloraBloom is added while a plant is fruiting and/or flowering.

Easy to Use?

Over the past 40 years, they've managed to work most of the kinks out of this product. The bottles are basic and serve their function, but actually have a couple of plus-ups over some other brands:

  • Every bottle has the feeding schedule for all 3 parts clearly printed on the back, which is very convenient at feeding time.
  • The designs on the bottle are unique and so are the colors of the liquid. This make it easy to tell the three apart, which is helpful to keep your measurements straight.

The containers don't always pour out as cleanly as I would like and would benefit from a clean pouring spout - but this is a tiny issue overall.

For pH balance, I found the Flora series lowers the pH of my water more than I want it to. Starting with water pH measuring 6.8, I tended to measure closer to 5.2 after adding nutrients. Since I'm growing in coco, I prefer a pH over 5.5.

Good Value?

Overall, this is a good value. The purchase price is very low by market standard - the series with all three parts is under $25 USD for the pint sizes (~.5 liter) and under $30 for the full quart size!

Cheap doesn't alway map one-to-one with value though. In this case, there are two detractors from the overall value: 1) you use quiet a bit per feeding and 2) normal applications use more FloraBloom than the other two. In the first issue, this means that while you get a lot for a little, you use a lot each time compared to some other concentrated nutrients. On the second issue, this means that you will run out of FloraBloom earlier than the other two. If you plan to keep using this formula, this isn't a problem because you can buy FloraBloom by the single bottle.

Performance

My statement on the performance I've seen from the GH Flora series is that it's solid and commiserate with its cost. On the upside, it's a gentle and easy to use solution that doesn't seem to harm or burn plants easily. This makes it a great option for a beginners and casual growers. More advanced growers on the other hand, will see better performance and value from a more modern formula.
