I am using a heat mat inside a tent to germinate seeds. Seeds are inside a small container boxes inside some wet , folded paper.
Even though I have low power leds the temp tends to rise to 28-30celsius /86fahrenheit.
The boxes tend to get steamy. Is this too warm for the seeds?
Just wondering about a 50/50 failrate in germinating seeds. Are they “boilin”? What is a good temperature for a heating mat?
Does presoaking the seeds inside a water really help?
Does a product like rhizotonic help to germinate seeds? It reads about it in the bottle but how much is enough of that inside a litre spray bottle?
Any other tips how to improve germination/seedlings?
Thanks, great forum!
Welcome ! I will say this with the heat mat make sure and keep the paper towels or paper damp it will dry out quick. It should work fine for you. Good luck
26-28c is a good temp.
Good call on the damp paper towel inside a Ziplock bag and then in a light proof container.
Ensure the light proof container cna transfer heat to the seeds though, I personally use a foil bag, mylar bags or one from the taco/burrito kit works well lol
My set up was a little different. Not sure about the folded paper method. I used root riot plugs in a tray with humidity dome. Heating mat under that hooked up to a timer for 15min on/ 15 min off in darkness. In 3.5 days they sprouted.
I’ve been 100% with germination.
I never checked the temp during germination
Ok so you give consecutive boosts / cooldowns with the mat?
You don’t want it to get to hot. Warmth is key. You could also put some between the heating mat and your seeds i suppose.
No don’t give bursts, use a controller it will minimize that effect and keep it much more constant.
Get a good tail on the seeds first then toss them in your rapid rooter or nursery pots or whatever you choose solo cups etc.
