How to use Gaia Green dry amendments
Why growers switch
Liquid PK boosters vs. Gaia Green Power Bloom 2-8-4
Liquid PK Boosters
  • Another bottle to buy on top of your base nutrients
  • Measure and mix at every watering during flower
  • Easy to overshoot and lock out other nutrients
  • Salt-based P and K build up and require flushing
  • No secondary nutrients or trace minerals included
  • Feeds the plant directly, bypasses soil biology
Gaia Green Power Bloom
  • One product replaces PK booster, bloom base, and supplements
  • Top-dress once a month, water normally in between
  • Slow-release formula is forgiving, hard to burn at recommended rates
  • Organic inputs, no salt buildup, no flush required
  • 4.5% calcium, 2.3% sulfur, plus trace minerals from rock dust and greensand
  • Microbes break down ingredients on demand, nutrients stay in the root zone
What makes it work
High P, moderate K, low N: built for the demands of flower

8% phosphorus from four different sources 2% N, 8% P, 4% K

Bone meal, mineralized phosphate, fishbone meal, and rock phosphate each release at different speeds. That spread ensures phosphorus availability from the first week of flower through the final weeks of fruit set.

Low nitrogen, mostly slow-release, to avoid excess foliage in bloom

Only 2% total nitrogen, and 75% of that is water-insoluble (the opposite of All Purpose). This means a slow, steady background feed of nitrogen without the vegetative push that flowering plants don't need.

4.5% calcium and 2.3% sulfur already included

Calcium demand spikes during flower, especially around weeks 3 to 5. Bone meal, fishbone meal, and gypsum provide it here without adding a separate cal-mag supplement.

Glacial rock dust and basalt for trace minerals during heavy production

Flowering and fruiting plants pull hard on iron, manganese, and magnesium. Both rock dusts supply these trace elements along with dozens of micronutrients that single-ingredient bloom boosters miss.

Insect frass and humic acid keep the soil food web active through harvest

Late in flower, soil biology can slow down as organic matter gets consumed. Insect frass and humic acid act as food for beneficial microbes so nutrient cycling doesn't stall when plants need it most.

Pairs with All Purpose 4-4-4 for a complete veg-to-harvest system

Use All Purpose 4-4-4 during veg, then transition to Power Bloom at the flip. The two products share the same application rates, so switching is just swapping which tub you reach for.

Amendment calculator

What the math looks like

Monthly top-dressing in bloom

At 1 tbsp per gallon, a 5-gallon pot uses 5 tbsp per month. A 2 kg tub gives you roughly 7 months of monthly top-dresses for a single 5-gallon pot.

Pre-mixing flower soil

At 3 tbsp per gallon, one 2 kg tub pre-mixes about 60 gallons. That fills twelve 5-gallon pots at under $1.10 per pot.

Full cycle cost (veg + bloom)

One tub of All Purpose ($10.95) plus one tub of Power Bloom ($12.95) covers a full veg-to-harvest cycle for multiple containers. The bundle saves even more.

Compared to liquid bloom boosters

A bottle of Botanicare Hydroplex runs about $20 for 1 quart and still requires a separate base nutrient. One tub of Power Bloom at $12.95 handles the entire flowering stage on its own.

How to use it: transition, bloom, and re-amend

1

Transition at the flip with a 50/50 blend

When plants begin showing flowers, top-dress with a 50/50 mix of All Purpose and Power Bloom at 1 tablespoon per gallon of soil. This provides the phosphorus boost flowering needs while keeping some nitrogen available for the stretch.

2

Switch to 100% Power Bloom for peak flower

After the first top-dress, go full Power Bloom for the remaining bloom applications. Top-dress 1 tablespoon per gallon every 3 to 4 weeks. Scratch lightly into the surface and water in.

3

Stop top-dressing 2 to 3 weeks before harvest

Because dry amendments take about a week to break down, stopping 2 to 3 weeks before harvest lets the plant use what's already in the soil without adding more. No flush protocol needed with organic inputs.

4

Re-amend with All Purpose for the next cycle

After harvest, pull the root ball and re-amend with All Purpose 4-4-4 plus worm castings to reset the soil for veg. Let it cook 2 to 4 weeks, then plant again.

Questions
Frequently asked questions
Power Bloom is designed for the flowering stage. It has only 2% nitrogen, which isn't enough to carry most plants through vegetative growth. For a complete veg-to-harvest system, start with All Purpose 4-4-4 during veg and switch to Power Bloom when flowering begins. Some growers pre-mix a small amount of Power Bloom into their starting soil alongside All Purpose so phosphorus is available early for root development, but the majority of Power Bloom usage happens during flower.
Most growers start with a 50/50 blend at the first sign of flowering, then move to 100% Power Bloom for subsequent top-dresses. For autoflowers, some growers start with 70/30 All Purpose to Power Bloom during early veg, then shift to 50/50, then to 70/30 Power Bloom to All Purpose in late bloom. The exact ratio depends on your genetics and how heavy a feeder the plant is. If you're unsure, 50/50 at the transition and 100% Power Bloom after that is the simplest approach.
Yes. Any plant that flowers and fruits benefits from the higher phosphorus and potassium in this blend. Tomatoes, peppers, squash, cucumbers, strawberries, fruit trees, and flowering ornamentals all respond well. The application rate is the same: 1 tablespoon per gallon of soil as a monthly top-dress once the plant begins to flower or set fruit.
Power Bloom has a noticeable fishy, earthy smell when you open the tub and when you first work it into soil. That comes from the bone meal and fishbone meal. The smell fades within a day or two once it's watered in. It won't make your grow room smell long-term, but you'll notice it during application. If you're in a small apartment, apply near an open window.
The non-granulated version is a fine powder blend and is approved for organic agriculture. The granulated version compresses the same ingredients into pellets for easier broadcasting on lawns and large beds, but the granulation process means it is not certified organic. For containers and indoor growing, the non-granulated (powder) version is what most growers use. Happy Hydro carries the non-granulated, organic-approved blend.
Stop top-dressing about 2 to 3 weeks before you plan to harvest. Since dry amendments take roughly a week to break down and become plant-available, stopping early lets the plant finish using what's already in the soil. Unlike salt-based nutrients, organic amendments don't require a flush. The plant will naturally use up the remaining available nutrients during those final weeks.

Pleasant Scent, Effective Cleaner
Scent: Lemon Verbena Concentrate, Size: 32 Fl Oz (Pack of 2)
I love the delicate verbena scent in Mrs. Meyers Clean Day Multi-Surface Cleaner. It’s very mild compared to other common household cleaner’s like Mr. Clean (Mr. Clean is one that knocks me over and I can’t stand the smell). Many years ago it was fine, but the scent has changed and become stronger, and NOT for the better. Manufacturers on the whole, use way too much scent in their products, whether it’s laundry detergent, fabric softener, hygiene products and anything else that scent is added to. Just take a walk down the detergent isle of your grocery store and if you aren’t immune to scent, you will find it overwhelming. This cleaner is not overpowering and smells just like verbena, a fresh, clean, green smell. I also love the way it cleans my wood floors, sinks, countertops, stainless steel fridge, stove & dishwasher, & everything else I clean with it. It leaves the surfaces “squeaky clean” without any streaks. Is it a good deep cleaning cleaner? I don’t know for sure since I’ve never used it to clean up muddy, greasy, grimy, dirty areas in my home. It does remove dark marks on painted walls but I haven’t tried it on heavy dirt and grime. I imagine it’s comparable to Murphy's Oil Soap, which is another brand I love and have used for years. If the scent of cleaners is an issue for you, and you like verbena, you should love this cleaner. A little bit goes a long way in a bucket of water (for washing floors, etc.). I usually use allot less than is recommended (in everything from laundry detergent to household cleaners). Especially my laundry detergent. I used to use the recommended amount and found with concentrated products, the amount recommended is way too much. I could feel the soap in my clothing after the wash cycle finished. I had to re-rinse all my loads. Then I got smart and cut way down on detergent and included vinegar in the final rinse cycle. Manufacturers love to sell more product, so don’t go by what they state on the container. Use your own wise judgement. On a side note, I love Costco’s Industrial Strength powdered laundry detergent but I cut way back to 1/4 cup per med to large loads. The white dress shirts and tee shirts are much brighter & whiter compared with many other detergents I’ve used in the past. I highly recommend this product for all of the above reasons. Give it a try at least once. You may love it too!

Excellent cleaning product, but lavender is a bit too strong for me.
Scent: Lavender Spray, Size: 16 Fl Oz (Pack of 3)
I bought 3 bottles of the lavender cleaner, and have used it to clean a number of different surfaces. In one of the bathrooms, I used it to clean dust from 6-panel doors, the cabinets, the counter and sink, the inside and outside of the tub area, and the outside of the toilet. When I was done, everything in the bathroom looked so clean. Even the dust that collects in the corners of the 6-panel doors was gone. Next, I tried to clean stainless steel refrigerator in the kitchen. The refrigerator wasn't dirty, but it had streaks from water dripped from the ice maker and fingerprints. This cleaner didn't work as well on the refrigerator. Although it did remove the fingerprints and water streaks, it left streaks that I had to clean using another method. Actually, a clean washcloth and warm water worked very well to remove the streaks. This cleaner also left streaks on my built in stove that has a glass front. So, I don't believe this cleaner works well on reflective surfaces such as mirrors, glass, or stainless steel. Although it does clean these surfaces well, it leaves a residue that causes streaks. The last surface I tried cleaning today was some of my kitchen cabinets. These cabinets collect not only anything in the air from cooking, but, since I am a smoker, they also collect some nicotine. On the cabinets that I cleaned, this cleaner did remove stains from both as was evidenced by the washrags I was using. To-date, the only cleaner I have found that would effectively clean these stains was Windex. So, I was impressed at how well this cleaner worked. It was working so well, I wanted to keep going, but, unfortunately, ran out of time. Overall, I would recommend this cleaner for anything but mirrors, glass, and stainless steel. The lavender scent of the bottles I got was a nice scent, but a bit overwhelming in my opinion. Once I use up the bottles that I have, I will be trying one of the other scents, possibly the honeysuckle or lemon scents. UPDATE 05/21/25: We don't use our dining room which is furnished with a 40 year old solid wood dining room set. All too often the table is used for keeping appliances or other items that I plant to get rid of or need to find a permanent storage place. I finally got the table clear off and saw a decent layer of dust on it. So, I decided to try this cleaner on it. This cleaner not only removed all dust and spots on the table top but also the layers of old furniture polish. I was so pleased that the table was clean with a natural shine that did not feel oily. Now all I have to do is clean the rest of dining room furniture. I will definitely be using this cleaner. I hope this review was helpful for you.

Smells amazing while cleaning, light lasting fragrance
Scent: Peppermint, Size: 16 Fl Oz (Pack of 1), Scent: Peppermint, Size: 16 Fl Oz (Pack of 1)
I really enjoyed using this Mrs. Meyer’s Clean Day Multi-Surface Cleaner, especially because of the peppermint scent. It smells incredibly fresh and pleasant while you’re cleaning, not overpowering, just very clean and uplifting. I tested it on multiple surfaces including countertops, tables, and other everyday areas, and it performed well across the board. It cleans effectively without leaving residue or streaks, and it feels gentle enough for regular use. The only reason I’m giving it four stars instead of five is because the scent fades fairly quickly after cleaning. While it smells amazing at first, the fragrance doesn’t linger for very long. That may be a plus for people sensitive to strong smells, but if you’re looking for a long-lasting scent, this might fall a bit short. Overall, it’s a solid multi-surface cleaner with a beautiful scent and reliable cleaning performance. I’d definitely repurchase, especially during seasonal releases.

Bang for your buck
Scent: Lemon Verbena Concentrate, Size: 32 Fl Oz (Pack of 2), Scent: Lemon Verbena Concentrate, Size: 32 Fl Oz (Pack of 2)
The amount of spray bottles you get from this concentrate is actually insane. I won’t have to buy surface cleaner until next year. No but seriously, this is a great price point and you get so much from it. All of the Mrs Meyers products have awesome conscious ingredients that I feel comfortable having around my kids and pets (and they’re insanely gross creatures too) The scent is just a cherry on top!!

a miracle in a jar
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
This item did exactly what it was expected to do, and I couldn’t be happier with my purchase. It works as described, is easy to use, and the overall quality exceeded my expectations. The price was great for what you get, making it an excellent value. Everything about it—from performance to convenience—has been spot on. My sister has noticed an extreme growth in her hair since using this product. I’m very satisfied and would definitely recommend this to anyone looking for something reliable and well worth the money!
