General Hydroponics Flora Series Trial Pack | 3pc - 32oz FloraMicro, 32oz FloraGro, and 32oz FloraBloom

Three-Bottle Starter Set for the Flora 3-Part Feeding System

Committing to three separate full-size bottles is a lot to ask before confirming the Flora Series feeding schedule works for your setup. The General Hydroponics Flora Series Trial Pack bundles one 32oz bottle each of FloraMicro, FloraGro, and FloraBloom, letting growers run the complete 3-part system at a smaller scale first.

All three bottles follow the same GH Flora Series feeding chart as the full-size line, so growers who like the results can reorder any single component in a larger size once they scale up.

Key Features & Benefits

Who Should Use This Trial Pack

New growers starting with the GH Flora 3-part system, or experienced growers evaluating the Flora Series before committing to full-size bottles, will find the Trial Pack a lower-cost way in.

Frequently Asked Questions

What's included in the Flora Series Trial Pack?

It includes one 32oz bottle each of FloraMicro, FloraGro, and FloraBloom — the three components of the GH Flora Series feeding system. All three are the same formulas sold individually in larger sizes.

How do I mix the three Trial Pack bottles together?

Add FloraMicro to your reservoir water first, then FloraGro or FloraBloom depending on growth stage, following the ratios on the Flora Series feeding chart. Adding FloraMicro after the other two raises the risk of nutrient lockout in a concentrated mix.

Is the Trial Pack enough nutrient for a full grow cycle?

It depends on the number of plants and reservoir size, since 32oz bottles are sized for evaluation rather than a full commercial cycle. Many home growers can complete one full cycle on a smaller setup before needing to reorder.

Can I reorder just one component after finishing the Trial Pack?

Yes, FloraMicro, FloraGro, and FloraBloom are each sold individually in sizes from 16oz up to 275gal totes. You are not required to reorder the bundle as a set.

Does the Trial Pack work in soil as well as hydroponics?

Yes, all three Flora Series components are compatible with hydroponic, coco, and soil growing setups. The feeding chart notes any adjustments needed for soil versus hydroponic use.
