Germination Tutorial

This week we take look at some basics; germinating.

Below you will find the A-Grade germination guide we offer to customers who are in need of guidance with new seeds.

This germination tutorial will guide you, step by step through germinating seeds with extremely high rates of success.


When germinating seeds there are a few basic steps that must be followed, here they are; 

  • Pre-soak your grow cubes in a mix of Ryzofuel (0.75ml>1L) & water.


  • Prepare propagation tray kit (base, insert tray and lid)


  • Remove cubes from solution and give a gentle squeeze so the cubes are not saturated but are still holding a substantial amount of solution.


  • Place seeds “pointy” end facing down and push in so the husk of the seed is about 1-2mm under the hole surface level.


  • Place dome on tray and close all the vents – 100% humidity until it germinates


  • If the seed has not germinated within 7 days add some of the Ryzofuel solution (same dosage) and pour approx. 100-200ml into the tray 


  • Most of the time if the conditions are flawless the seed will say hello around day 2-5


  • If you have a T5 propagation light place this on top of the dome or mounted closely above (Note: light is not required to germinate the seed, so the reason we do this is because once the seed does emerge, rather than letting it elongate, so by having the light in place the seed will immediately be lit instead of looking for it causing the growth to stay strong and stout) 


  • Once the seed has germinated the first 2 sets of leaves will be round these are called cotyledons, the set of serrated leaves that emerge after this will be your first “true set “of leaves.


  • Once we have the first true set, the vents can be opened to reduce humidity to around 75-80% - this is called the hardening phase, if the seed is inferior it will fall over, the tough ones stand tall (most seeds will be good these days)


  • Some gardeners do prefer to to leave the seedling in the dome until the 3rd or 4th set of true leaves, from here we can transplant into our pot system.


  • For the first few days in the system top feed your nutrient mix to ensure the collar of the stem does not dry out, after 3-5 days of doing this your root system should have made it to the reservoir (If using a DWC system), from here its all maintaining the nutrient mix and the plant will do the rest.
