Increasing Flower Density using a Bud Hardener?

Pouring your heart and soul into your grow and ending up with popcorn light and fragile bud? Many growers have the same complaint. Below we discuss how you can grow a fat bigger & denser bud Before we do that, let us talk about why this is important. The apparent reason is that no one wants light airy weak bud.

The solution is pretty simple: A Bud hardener. If you have all your other grow factors dialed in and are using the best seeds but still cannot seem to get the results you want, a bud hardener might be what you are missing.

Before we get into the Whys and Whats of Bud Hsupplement with CO2ardeners, let us first understand the factors that affect the flower density.

Factors that affect Flower Density?

Growing a healthy and dense flower involves many factors that you need to keep in mind. These include:


The key to growing a high-quality plant is pushing the specific seed's limits to maximize its genetic potential. If youre working with a sub-par strain then there isn’t much you can do. With old weak clones or seeds, the results will always be disappointing. You can use the best grow lights, the best nutrients, dial-in VPD, and supplement with CO2 you still won't get anywhere when the seed lacks the genetic potential.

Plant Nutrition and Bud Density

Low-quality fertilizers, or those in the incorrect ratios, can affect your flowers' bud density, resulting in lackluster buds.

Many people understand and acknowledge the effects of under-feeding the plant with fertilizer. However, some people seem to miss how overfeeding the plant can be just as detrimental.

Did you know, overfeeding plants with Nitrogen results in lean and thin buds? We suggest checking out our article on the ideal nutrient ratios across different growth stages to avoid this ordeal.

Grow Lights and Bud Density

Choosing the right to grow lights is vital if you want dense buds. Weak grow lights cannot give you the same result as they cannot adequately penetrate through the canopy, only reaching the plant's top-most parts. Similarly, not following a light schedule according to your plant's needs can also inhibit growth.

An easy fix for this is plant training, using LED, CMH, or HPS grow lights. If you want to learn more about grow lights, we recommend reading our yearly review on the best LED grow lights.

A bud hardener is an additive you can use at the end of the flowering cycle to dense up your flowers and also add weight.

They are generally used in the last 3 weeks of the grow cycle, ad contain a mix of macronutrients, micronutrients, minerals, necessary oils, and so on.

They help reduce stress on your plants, while not making them denser, but help with increasing terpene as well as flavonoid creation too!

Should I Use A Hardener?

A big percentage of new growers are dissatisfied with their yields and quality, and the knee jerk reaction is to begin feeding your plants all kinds of additives.

The fact is, no amount of bud hardener can rectify the issue of substandard genetics, illumination, environmental protections, nutrients, etc.
