Hydroponics Supplies & Indoor Growing Equipment
Hydroponics is the practice of growing plants in a soilless environment — delivering water, nutrients, and oxygen directly to plant roots. Without the variability of soil, hydroponic growers control every input precisely, producing faster growth, higher yields, and year-round harvests independent of outdoor growing seasons. From a single DWC bucket on a shelf to a full commercial CEA facility, every supply category is here.
25,000+ Products Across Every Growing Category
Hydrobuilder stocks complete hydroponic systems (DWC, drip, NFT, ebb and flow, aeroponics), grow lights (LED and HID), nutrients and pH management, growing media (coco coir, rockwool, perlite, soil), grow tents, fans and ventilation, dehumidifiers, irrigation components, environmental controllers, meters and testing supplies, pest control, and harvesting equipment. Qualified brands include Athena, General Hydroponics, HGV, Grodan, Netafim, FloraFlex, Active Aqua, Growers Choice, Botanicare, Quest, TrolMaster, and more — all verified for real-world performance by growers who use them.
Hydroponic Growing Methods
The most common soilless methods available here: deep water culture (DWC) suspends roots in oxygenated nutrient solution; ebb and flow periodically floods and drains a grow tray; drip systems deliver programmed nutrient feeds to individual plants; nutrient film technique (NFT) runs a continuous thin solution film over root mats; aeroponics mists roots suspended in air for maximum oxygen exposure. Grow media options — rockwool, clay pebbles, coco coir, and perlite — support root systems in media-based setups. Use our Nutrient Mixing & Dilution Calculator to plan feeding programs, or the Pump & Irrigation Flow Calculator to size your system correctly.
What Can You Grow Hydroponically?
Almost anything you can grow outdoors can be grown hydroponically indoors. Leafy greens (lettuce, spinach, kale), herbs (basil, cilantro, mint), fruiting crops (tomatoes, peppers, cucumbers, strawberries), root vegetables, and specialty crops all thrive in well-managed hydroponic systems. CEA production of vegetables and herbs now accounts for billions in commercial food production globally — the same systems and inputs are available to home growers here at any scale.
Beginner to Commercial — Expert Support Available
Hydrobuilder serves home hobbyists growing vegetables and herbs indoors alongside commercial greenhouse and indoor farm operators. Our expert cultivation support team — growers themselves — is available to help size systems, troubleshoot nutrient deficiencies, and configure fertigation setups. Commercial accounts with volume pricing are available for large-scale operations, and our CEA ROI Calculator can help model production economics before you build.

Hydroponics FAQ
What is hydroponics and how does it work?
Hydroponics is a method of growing plants without soil — delivering water, nutrients, and oxygen directly to plant roots in a soilless medium or directly in nutrient solution. Because plants receive exactly what they need directly at the root zone, they typically grow 20–50% faster and produce higher yields per square foot than equivalent soil-grown plants. The most common hydroponic methods are deep water culture (DWC), drip irrigation, ebb and flow, NFT (nutrient film technique), and aeroponics — each delivering nutrients differently but all operating on the same principle of soilless root zone feeding.
What can you grow hydroponically?
Almost any plant that grows in soil can be grown hydroponically. Leafy greens (lettuce, spinach, kale, arugula), culinary herbs (basil, cilantro, mint, parsley), fruiting vegetables (tomatoes, peppers, cucumbers, strawberries), and root vegetables all thrive in well-managed hydroponic systems. Commercially, hydroponic production of tomatoes, cucumbers, leafy greens, and herbs now accounts for a significant share of indoor produce supply in North America. CEA (controlled environment agriculture) professionals use the same systems and inputs available here at any scale.
Is hydroponics better than soil growing?
For indoor controlled environments, hydroponics typically produces faster growth, higher yields per square foot, and more precise nutrition management than soil growing. Soil growing has lower upfront complexity, more microbial buffering against mistakes, and lower per-cycle input costs. The right choice depends on your goals: hobby growers who want simplicity often start with soil and transition to hydro after gaining experience; commercial operators almost universally use soilless or hydroponic methods for productivity and space efficiency. Both approaches are well-supported by Hydrobuilder's product catalog.
How much does it cost to set up a hydroponic system?
Entry-level: a single-plant DWC bucket, small LED, clip-on fan, and basic nutrients can be set up for $150–$300. Mid-range: a 4x4 tent with a 600W LED, 4-plant DWC or drip system, ventilation, and nutrients runs $600–$1,200. Commercial: a complete 10x10 production setup with quality LED fixtures, automated fertigation, and climate control starts at $5,000–$15,000+. The biggest cost variables are lighting quality and automation level — both can be scaled incrementally as your operation grows.
