£84.00

A highly concentrated flowering additive designed to stabilise pH during bloom and support fuller flower development.

Rambridge Blossom Blood is a specialist flowering additive developed for use once flowers are established. Rather than acting as another conventional plant food, Blossom Blood uses a specific type of pH buffer salt to help maintain the acidic conditions required during flowering.

This makes it easy to incorporate alongside an existing quality nutrient programme without replacing your normal base feed. It was developed for hydroponic applications and can also be used with soil and soilless growing media.

Blossom Blood is extremely concentrated. Just 1g treats 10 litres of hydroponic nutrient solution, giving a 300g tub enough product to prepare up to 3,000 litres at the full published application rate.

Why choose Blossom Blood?

  • Specialist flowering additive – developed specifically for use during the flowering stage.
  • Selective pH control – uses a specialised pH buffer salt to help maintain acidic conditions during flowering.
  • Supports fuller flower development – designed to promote floral production once flowers are established.
  • Highly concentrated – only 1g is required per 10L of hydroponic nutrient solution at full strength.
  • Treats up to 3,000 litres – one 300g tub provides a substantial volume of working solution.
  • Works alongside your base nutrients – compatible with quality nutrient programmes rather than replacing them.
  • Suitable for different growing methods – established directions cover hydroponic and soil applications.

What is Blossom Blood used for?

Blossom Blood is intended for the flowering stage, once flower buds are well established. Its role is different from a conventional bloom fertiliser. The formulation is based around pH buffering, helping maintain suitable acidic conditions during this important stage of plant development.

It is particularly well suited to hydroponic growers, where it can be mixed directly into the nutrient reservoir. Blossom Blood can also be used with soil-grown plants at the appropriate lower concentration.

Because Blossom Blood is an additive rather than a complete plant food, continue using your normal base nutrient programme alongside it.

How to use Blossom Blood

Begin using Blossom Blood when flower buds are well established. Mix thoroughly into the nutrient solution and always measure the small quantity required carefully.

Hydroponics: Mix 1g of Blossom Blood into every 10 litres of nutrient solution. The published directions recommend beginning at half this amount and assessing the plant response before progressing to full strength.

Soil: Dissolve 1g into 20 litres of water. Apply approximately 500ml of the prepared solution per plant once flower buds are established.

Published directions recommend repeating the application after approximately two weeks or at the next nutrient change. Mix thoroughly before use. Blossom Blood is intended for root-zone application and should not be used as a foliar spray.

When should I start using Blossom Blood?

Start using Blossom Blood once flower buds are well established. It is specifically intended for the flowering stage rather than vegetative growth.

How much Blossom Blood should I use in hydroponics?

The full published rate is 1g per 10 litres of nutrient solution. The directions recommend starting at half strength because plant response can vary.

How much solution will a 300g tub of Blossom Blood make?

At the full hydroponic application rate of 1g per 10 litres, a 300g tub can treat up to 3,000 litres of nutrient solution.

Can Blossom Blood be used in soil?

Yes. For soil applications, dissolve 1g of Blossom Blood into 20 litres of water and apply approximately 500ml of the prepared solution per plant once flower buds are established.

Can Blossom Blood be used with other nutrients?

Yes. Blossom Blood is designed as an additive and is compatible with quality nutrient programmes. Continue using an appropriate base nutrient alongside it.

Can Blossom Blood be used as a foliar spray?

No. Blossom Blood should not be used as a foliar spray. Apply it through the nutrient solution or root zone according to the appropriate growing method.

Is Blossom Blood a PK booster?

No. Blossom Blood should not be confused with a conventional high-phosphorus and high-potassium bloom fertiliser. Its principal function is as a specialist pH-buffer additive for the flowering stage.
