it ain’t the plug , it is something else…could be the seed genetics , temps , water , humidity , etc etc or a combination of circumstances
we have used grow plugs to start a lot of seeds and have only lost a few
nothing is going to be 100% successful in this hobby
been using Rapid Rooters but switching over to these new ones , Flora Flex 40/40
Process
Pre-Soak the 40/40 plugs by pouring them into your B1:B2 Nutrient solution and allow them to soak for a minimum of 2 minutes.
Place the 40/40 cubes in the Incubator 50 Cell Inner Tray.
Start seeds by placing them into the center hole of the 40/40 cube, push half way down. (Can use a toothpick or similar object to push the seedling down).
Tip: Enusre that seedlings are labeled in the propogation tray using plant tags.
Place the Incubator Dome on the Incubator tray. Ensure that all vents are fully closed to allow moisture to build up inside the dome.
Place the Incubator Kit under your light. Do Not turn the light on for the first 12-36 hours.
Within 2-7 days you should begin to see all of your seedlings begin to sprout out of the 40/40 cubes.
Once the seeds sprout open the top vents of the Incubator, then slide it to the side to allow air flow through our patented convection design.
Remove the domes completely once the seedlings started growing and have established a nice root system and have at least 2-3 sets of fan leaves and/or are the size of a clone. Typically 10-14 Days after seedlings were planted.
Environment
Light Cycle - 18-24 Hours
Light Intensity - 80-160 umol
Inside Dome Temp - 75-80 Degrees
Inside Dome Humidity Germination - 75-80%
Inside Dome Humidity Sprouted - 65-70%
Tips:
- Turning the lights on before the seedling have germinated encourages them to grow in the upwards direction towards the light.
- Lights should typically be hung 8-16" above the clone dome
- You can measure the temps and humidity inside the with a Hygrometer. One with an extendable probe is ideal.
- If temps are low raise the temps in the room. If that is not an option, add a heating mat under the Incubator Tray.
- If the temps are high try raising your lights or lowering the temperate in your room.
- Once seedlings have sprouted ensure that the humidity levels in the dome are lowered to prevent them from dampering off. If humidity is not lowering in the dome with the vents opened and dome slid to the side increase air movement in the room and/or take the dome off daily to wipe down condensation inside the dome and place it back on.
- Too much light early on can cause the seedlings to droop and stress.
Watering
Replace the nutrient rich water at the bottom of the tray every 2-3 days.
Tips:
- Do not top feed the 40/40 plugs until you squeeze them and do not moisture rise out the top. Wet growing medium leads reduces oxygen levels in the medium and lead to rotting stems.
- If the cubes are not drying out remove water from the bottom of the tray and take the dome off daily for 30-60 minutes.
