Question and Answers

Organic and synthetic fertilizer

Is Reefertilizer Grow Organic?
Grow is a synthetic fertilizer while our Start soil conditioner is organic.
The advantage of synthetic fertilizer like Grow is that nutrients are immediate available to plants.
The Reefertilizer organic and synthetic combo fertilizer provide the benefits of both.

Reefertilizer grow vegetables

Can I Use Reefertilizer For Other Plants in My Garden?
Reefertilizer is safe for all consumable plants like cannabis, vegetables, and edible flowers. Our nutrients are vegan and have low heavy metal counts compared to other brands, take a look at our COAs.

When to feed cannabis plants

When do I start feeding my plants Reefertilizer Grow?
You can start feeding your plants when they have their first 3 to 4 sets of leaves. One plant that size might not need a whole 4L of nutrient solution. In that case you can split the dose in half. So instead of 1 scoop in 4L, you would do 1/2 scoop in 2L. The ratio is what’s important. You can use any volume of nutrient solution you want if you maintain the recommended nutrient-to-water ratio.

Measure cannabis nutrients

How much do I feed my plants?
Start with 1 scoop (5ml) for every 4L (1 gallon) of water. Feed each plant weekly with enough of this solution to fully saturate the soil and have a bit of runoff. You can water your plants as needed in between feedings. Some folks split the dose and feed twice a week. Both work fine, pick whichever method is easier for you.

Mixing Cannabis Nutrients

Can I pre-mix these nutrients?
Because these are chelated nutrients they don’t do well being mixed into water and stored for long periods of time. The elements within the solution can react with each other and lower the effectiveness of the fertilizer. A few days is okay, but anything longer than a week might not be a good idea.

The Reefertilizer difference

What makes Reefertilizer Grow different from other veg fertilizer?
Other veg fertilizers usually need to be used with additional inputs. Reefertilizer Grow has a NPK ratio perfect for cannabis in flower as well as all the other micronutrients beneficial for the veg period.
Enhanced with magnesium, Reefertilizer Grow reduces the number of additional inputs you might need.
Our goal at Reefertilizer is to get more folks growing their own cannabis. Reefertilizer provides easy-to-use and affordable nutrients along with straightforward guidance and support.
We designed our products to be lighter and have less packaging than our competitors and we’re happy to offer a 30-day return policy if you’re not happy with our products.
We’re not “big fertilizer”, we’re just three guys who love growing and using cannabis.

First time user and had great results for the "Grow" phase! It was easy to measure with scoop included with Grow Reefertilizer. Would have loved to try the Bloom Reefertilizer, but they've been sold out for a while... Couldn't wait.l, sorry ;(...

I have another Bakerstreet Indica plant under way and it’s now 57 days old. It’s in a 1.75 Gallon pot and is under a FLUVAL 6500K Plant Spectrum LED System. I administer 1 litre of water with one teaspoon of the Grow Compound once a week. The leaves on the plant actually start to stand up at around 07:00 PM every night and stay that way until 06:00 AM the next morning. I read an article that said that this means the plant likes what is being done. I did see “Clawing” on the Fan Leaves so last week I flushed the plant with straight water (Ph level 6) and it’s been doing well. I resumed the watering once again this morning after 7 days with one litre of water mixed with one teaspoon of Grow Compound and the plant looks good. I have provided two photos for your assessment.
