Professors Nutrients Organic Flower Boost (1L / 5L - Certified Organic)

What is Professor’s Nutrients Organic Flower Boost used for?

It’s a certified organic PK enhancer designed to support flower and fruit development. It promotes bigger, heavier blooms, better bud structure, and improved flavour potential in both edible and ornamental plants.

When should I start using Organic Flower Boost and how often?

Begin at the first signs of flowering or bud set. Apply weekly or with each feed through the bloom phase. Many growers taper off in late flower to keep the finish clean. Adjust based on your base nutrient and plant response.

What types of growing media is Organic Flower Boost compatible with?

It works in soil, coco, hydroponics, and inert media like rockwool or perlite. It’s suitable for both indoor and outdoor gardens, and integrates well into most organic or blended nutrient programs.

How do I mix and dose Organic Flower Boost?

Start with 2 mL per litre of water and increase to 4 mL only if plants are thriving. Mix well before applying. For most growers, it’s added into their base bloom feed once flowering begins.

What nutrients are in Organic Flower Boost?

It’s low in nitrogen and rich in phosphorus and potassium, with added calcium, magnesium, sulphur, trace elements, amino acids, and humic and fulvic acids for improved nutrient delivery.

Is Organic Flower Boost safe for edible crops and certified organic?

Yes—it's certified organic and safe for fruits, herbs, and vegetables when used as directed. It’s suitable for flowering ornamentals and fruiting crops like tomatoes, chillies, and berries.

What happens if I overuse Organic Flower Boost?

Too much can cause calcium/magnesium issues, burnt tips, or slowed growth. If that happens, pause feeding, maintain stable pH, and let the plant recover. In pots, a gentle flush may help.

Do I need to adjust pH after mixing Organic Flower Boost?

Possibly. Organic inputs can lower pH slightly. Aim for your media’s ideal range and adjust with organic-friendly pH solutions if needed. PK uptake is sensitive to pH drift.

Can I mix Organic Flower Boost with other nutrients or supplements?

Yes—but layer thoughtfully. It’s commonly used with base bloom feeds. If adding silica, cal-mag, or microbe products, follow correct mix order and monitor plant response. Avoid tank mixing with pesticides or oils.

Can I use Organic Flower Boost in drip or auto-irrigation systems?

Yes, but like all organics, it can build up over time. Always agitate mixes well, filter water if needed, and flush lines regularly to prevent clogs.

Can I use Organic Flower Boost as a foliar spray?

It's primarily a root-zone feed. Foliar use is possible but not common—if you try it, go light to avoid residue or stress on leaves, and never foliar spray under strong light.

How should I store Organic Flower Boost?

Keep it sealed, out of direct sunlight, and in a cool, stable location. Shake well before use, as organic components can settle during storage.

How quickly will I see results from Organic Flower Boost?

Expect visible improvement in flower set and development within 1–2 weeks of consistent use, especially when paired with a strong base nutrient and stable conditions.

What’s the difference between Organic Flower Boost and synthetic PK boosters?

Organic boosters feed more gradually and support soil biology. Mineral PKs act faster but can cause lockouts or burn if overdone. Organic is safer for long-term plant health and microbial balance.
