Great question — and it's one a lot of experienced growers ask once they’ve nailed down the basics.
Using only TA (Terra Aquatica) TriPart in DWC can absolutely give excellent results. It's a complete 3-part system that, when used correctly, provides all the essential macro and micronutrients. Many successful growers stick to base nutrients alone and still get potent, high-yielding harvests.
So, do boosters make a difference in flower quality?
Yes — but it depends.
When Boosters Can Help:
Optimized genetics + environment: If you're already maximizing your plant’s potential (great light, environment, and training), bloom boosters can fine-tune yields, resin production, and terpene profiles.
Specialized boosters like:
PK boosters (like TA FinalPart or similar) can bulk up flowers.
Carbohydrate additives may support microbial life in soil/coco (less relevant in sterile DWC).
Silica, amino acids, or enzymes can improve stress resistance, root health, or nutrient uptake.
When Boosters Might Not Be Worth It:
If your base nutrient regimen (like TA TriPart) is dialed in and your plants look happy and healthy, boosters might not bring a huge improvement.
In sterile hydro setups like DWC, many boosters meant for soil/coco (like organic teas or microbe-based products) don’t add much value.
Bottom line: Boosters can add a few percentage points of quality or weight if everything else is optimized. But they’re not magic — and many skilled growers get excellent results without them
