How Do I Choose the Right Propagation Equipment?
Propagation is where every grow cycle begins, whether you are rooting cuttings from a mother plant or germinating seeds for a new crop. EZ-CLONE and Psycloner build dedicated cloning machines that use aeroponics or deep water culture to root cuttings in 7 to 14 days. AC Infinity and VIVOSUN focus on heat mats, humidity domes, and germination kits designed for seed starting and early seedling growth. The right setup depends on whether you are cloning established genetics or starting from seed, and how many plants you need to propagate per cycle.
What Size Cloner or Propagation Setup Do I Need?
Match your propagation equipment to the number of plants you run per cycle:
For growers who want to move rooted clones or seedlings directly into a recirculating system,
hydroponic growing systems pair naturally with propagation equipment as the next step in the growth cycle.
What Should I Look for in Propagation Equipment?
-
Cloning method: Aeroponic cloners like the
Psycloner 140 mist exposed root zones continuously, which typically roots cuttings faster than deep water culture. Deep water cloners like the
Psycloner 24 submerge stems in oxygenated water and require less monitoring.
-
Heat mat sizing: Match the mat to your tray count. A 10" x 20.75" mat fits a single standard 1020 tray. A 48" x 20.75" mat covers four trays side by side, which is more efficient for larger seed-starting operations.
-
Temperature control: Seedling heat mats with a built-in thermostat, like the
VIVOSUN 10" x 20.75" with dual digital thermostat, maintain a consistent root zone temperature between 68-86°F. Mats without thermostats can overheat and damage seedlings.
-
Humidity dome features: Look for adjustable vents and LED light bar integration. The
AC Infinity 6" x 12" propagation kit includes height-adjustable domes that accommodate taller seedlings as they grow.
-
Integrated lighting: Seedling light gardens from SunBlaster combine T5 or LED fixtures with a growing tray, which simplifies setup for small-batch seed starts and herb propagation.

Frequently Asked Questions
How many clone sites do I need for a home grow?
For a typical home grow running 4 to 8 plants per cycle, a 16 to 24 site cloner provides enough capacity. Taking extra cuttings accounts for the 10-20% of clones that may not root successfully, so a 16-site machine for a 4-plant grow or a 24-site unit for an 8-plant grow gives you a comfortable margin.
What is the difference between an aeroponic cloner and a deep water cloner?
Aeroponic cloners spray a fine mist onto the cut stems at timed intervals, exposing roots to both water and air simultaneously. This method typically produces visible roots in 5 to 10 days. Deep water cloners keep the stems submerged in aerated, oxygenated water, which is simpler to maintain but may take a few extra days. Both methods outperform traditional rooting in soil or rockwool for speed and success rate.
Do I need a seedling heat mat for germination?
A heat mat is not strictly required, but it significantly improves germination rates and speed. Most seeds germinate best when the root zone stays between 70-80°F. Without a heat mat, ambient room temperatures in cooler climates can slow germination by days or cause uneven sprouting. A thermostat-controlled mat keeps temperatures consistent and prevents overheating.
What size heat mat fits a standard 1020 propagation tray?
A 10" x 20.75" heat mat is designed to fit directly under a single standard 1020 tray (10" x 20"). For two trays side by side, use a 20" x 20.75" mat. The 48" x 20.75" size accommodates four 1020 trays in a row, which is the most efficient option for larger seed-starting setups.
Can I use a cloning machine inside a grow tent?
Yes, many growers run cloning machines inside small 2x2 or 2x4 tents to control humidity and temperature independently from the main flowering area. The tent keeps humidity around 70-80% RH, which is ideal for clone rooting. Proper ventilation is still important to prevent mold, so a small inline fan with light air exchange works well.
How often should I change the water in a cloning machine?
Change the reservoir water every 5 to 7 days to prevent bacterial buildup. Keep the water temperature between 68-72°F, as warmer water promotes pathogen growth while cooler water slows root development. Using a rooting solution and maintaining clean collars between batches also reduces the risk of contamination.
What is the advantage of a humidity dome with built-in LED lights?
Integrated LED bars provide gentle light directly above seedlings without needing a separate fixture or hang kit. This keeps the setup compact and reduces heat buildup compared to overhead grow lights. The low-intensity output (typically 10-20W) is tuned for seedling growth rather than flowering, which prevents stretching and promotes stocky, healthy starts.
