Flower Universal Liquid Fertilizer is the ultimate all-rounder for your grow op and garden, designed to simplify your life while maximizing the vitality of your plants. This balanced nutrient solution acts as a powerful energy shot, providing a perfect NPK ratio (7-5-6) enriched with algae extract and a Vitamin B complex to ensure your green pets—whether they are decorative, aromatic, or productive—grow strong, stress-free, and with a color that will make your neighbors jealous.

Are you tired of playing chemist with a dozen different bottles just to keep your terrace or grow room alive? Many growers fall into the trap of buying a specific product for every single plant, turning their shelf into a chaotic and expensive mess.

This not only drains your wallet but also increases the risk of mistakes. Mixing the wrong nutrients or overcomplicating the schedule often leads to nutrient lockout, burnt tips, or sad, yellowing leaves. You end up with more stress than results, and your plants pay the price for that confusion.

The solution is simpler than you think: Flower Universal Liquid Fertilizer offers a versatile and scientifically balanced formula that works across the board. By combining essential macronutrients with the bio-stimulating power of algae, you get a single product that covers the nutritional needs of almost everything you grow, saving you time, money, and headaches.

Your Domestic Jungle: Indoor and Balcony Plants

If you are the type of person who loves having a green corner at home, this fertilizer is your best ally. Indoor plants often suffer from lack of light or poor soil aeration in Indoor and Outdoor Planters. The Vitamin B complex in this formula acts as a "stress shield," helping them cope with indoor conditions while the algae extract boosts photosynthesis.

The result? Ficus, Pothos, and Monsteras with intense, shiny green leaves. It’s as easy as adding a capful to your watering can; you don't need to be an expert to see professional results in your living room.

The Smart Grower's Backup: Maintenance and Veg

For the serious cultivator focused on high-performance crops, this bottle is the perfect "Swiss Army Knife" to have on hand. While you might use specific cannabis fertilizers for your main flowering run, Flower Universal is unbeatable for maintaining mother plants or giving a nitrogen boost during the vegetative stage of your outdoor guerrilla grow.

Its high nitrogen content (7%) ensures explosive vegetative growth, making it ideal for recovering plants that look a bit pale or for prepping your soil mix before the season starts. It’s the reliable, low-cost option that never fails.

How to choose the best use for you

Not sure if this is the right bottle for your setup? Here is a quick guide to help you decide:

  • If you want simplicity: Ideal if you have a mix of ornamental and aromatic plants and want one product for all of them.
  • If you are on a budget: Perfect for keeping your garden lush without spending a fortune on specialized lines.
  • If you are a pro grower: Excellent for mother plants, cuttings that have rooted, and vegetative growth in soil.

Advantages and benefits of the Algae & Vitamin Formula

  • Bio-stimulation: The algae extract acts as a natural booster, accelerating metabolism and nutrient uptake.
  • Stress Resistance: Vitamin B helps plants recover from transplant shock, drought, or temperature changes.
  • Versatility: Works perfectly in any Universal Substrate, both for root watering and foliar feeding.
  • Balanced NPK: The 7-5-6 ratio prevents deficiencies without the risk of salt buildup when used correctly.
  • Economy: High concentration means one bottle lasts a long time (1 cap per 4-5 liters of water).

Frequently Asked Questions

How do I dose Flower Universal Liquid Fertilizer?

It is very concentrated. For root irrigation, dissolve 1 cap (approx. 20ml) in 4 to 5 liters of water. If you want to do a foliar spray to correct deficiencies quickly, use half a cap in 4 liters of water and spray the leaves (always with lights off or at sunset).

How often should I use it?

During the active growing season (Spring and Summer), apply it once a week. In Autumn and Winter, when plant metabolism slows down, reduce the frequency to once or twice a month.

Can I use it on autoflowering plants?

Yes, it is great for the vegetative phase of autoflowers due to its nitrogen content. Once they start flowering heavily, you might want to supplement it with a specific PK booster.

Personal Experience of Pevgrow’s CEO (Alan)

"I've always said that you don't need a PhD in chemistry to have a nice garden. I keep a bottle of Flower Universal in the office for all our decorative plants, and honestly, they look radioactive green. But my personal trick? I use it on my mother plants kept in soil. The Vitamin B keeps them super healthy despite the constant pruning for cuttings. It's cheap, it works, and it smells like victory."
