Veg+Bloom RO/SOFT Base — One-Part Powdered Nutrient for Soft Water & RO Systems
Best for: Growers using RO water or soft water (under 0.3 EC) in hydroponic systems, coco, or rockwool who want simplicity and professional-grade results without the multi-part complexity
Our thoughts
If you're running RO water or soft water and sick of juggling three-part nutrient systems, this is a proper game-changer. One-part powder, professionally formulated, pH-stable out of the box, and shipping costs you a fraction of what liquid nutrients would. We rate it highly for growers who want to scale without overcomplicating the feed.
Veg+Bloom RO/SOFT is a one-part powdered base nutrient specifically formulated for growers working with soft water (below 0.3 EC) or reverse osmosis water. Unlike three-part liquid systems, you get everything you need in a single powder — macronutrients, micronutrients, amino acids, fulvic acids, bioactive growth stimulants, and silica — all blended to work together from vegetative growth through to the end of your cycle.
It's built for hydroponic systems (NFT, drip, aeroponics) but works just as well in coco, rockwool, and other inert media. The real kicker: it's pharmaceutical-grade, powdered format means lower shipping weight, longer shelf life, and a fraction of the cost-per-use compared to liquid alternatives. This is the nutrient professional growers scale with.
How it compares
Most hydroponic nutrient systems fall into three camps: three-part liquid (General Hydroponics Flora), two-part powder (Athena Pro Line), or one-part powder (this, or General Hydroponics Maxi Series).
-
vs. three-part liquid systems: You lose mixing complexity and pay for shipping water weight. GH Flora is solid but you're juggling three bottles and paying liquid shipping costs.
-
vs. two-part powder systems: Athena is professional-grade but costs more. Veg+Bloom does the same job in one bottle at a lower price point.
-
vs. one-part powder competitors: General Hydroponics Maxi is trusted and established. Veg+Bloom is formulated specifically for soft/RO water — if that's what you're running, this is the smarter choice. If you're on hard tap water, Maxi might edge it.
Bottom line: if you're on soft water or RO and want one bottle instead of three, this removes a layer of guesswork.
Usage guidance
Veg+Bloom RO/SOFT is dead simple to use, but water quality matters.
For RO or soft water users (under 0.3 EC)
Dissolve the powder into your final water volume and check pH. That's it. It's formulated to drop your pH into the working range of 5.6–6.5 automatically, so you're not chasing pH swings like you would with other powders.
Mixing ratio
Use only what you need per watering. A teaspoon or two per gallon is typical, depending on your system and growth stage. Start conservative and adjust based on plant response.
For hydroponic systems (drip, NFT, aeroponics)
Dissolve into your reservoir and run normally. Works in drain-to-waste or recirculating systems. Keep your EC stable by topping up with RO water, not fresh nutrient mix.
In coco or rockwool
Hand water or automated, same principle. Let your medium drain properly and feed to roughly 10–20% runoff per watering to avoid salt buildup.
Adding boosters and additives
Veg+Bloom plays well with others. You can layer in PK boosters (like Shine) from week three of flowering, or probiotics like +LIFE for healthier plants. Just reduce the base nutrient slightly if your additive contains NPK, otherwise you'll overfeed.

Who this is for
- Growers on soft water or running RO systems (especially in Scotland, Wales, and South West UK where water is naturally soft)
- Anyone who's tired of juggling three-part or two-part systems and wants one bottle that works
- Growers scaling up operations where per-use nutrient cost matters
- Hydroponic specialists running drip, NFT, or aeroponics on tight margins
- Coco and rockwool growers who want professional-grade nutrition without the premium price tag
- Growers who value transparency and pharmaceutical-grade purity over brand recognition
Our take
This is proper professional-grade nutrition in powder form. One bottle instead of three, formulated specifically for soft or RO water so you're not fighting your water chemistry, and priced sharply enough that scaling doesn't become a budget killer.
If you're on soft water or RO and currently mixing a three-part system, switching to this will free up time and money. Does exactly what it should, and the grower feedback speaks for itself. Worth picking up while clearance stock lasts.
