finding the right place to put germing dish is tricky usually what i want to use takes no more than 3 days to germ..longer than that its probally not gonna happen
I agree, but when you google it you get a huge variation in answers and people divided right down the middle between using light from the get go and not using light until the seeds sprouts. Just surprising to me that there is such disagreement..........
Yep. Although I don't use a heat mat so its partially helping with warmth in addition to giving light once they break the surface. Plugging the hole definitely does a good enough job blocking light for the seed to get going.
OK, a final question. Once the seed sprouts but is not ready to be transplanted yet, do you guys use a small fan to start the air circulation going? I have a very small fan that can blow some air just above the top of the sprouts, should I use it? I know air circulation is super important once the plants get into the grow room, but how about right before that?
The initial tap root is probably why you want to at least plug the hole, no? Kinda wondered if the open hole into the 3rd rockwool cube is why that one germinated then failed.
I like gentle air circ early. So long as you aren't completely drying out your rooters, it's probably beneficial. Getting breezed around will help strengthen the stems (and later the branches).
For indoor growing, I wouldn’t blow on them until you have 5-6 nodes established. But, especially not before they hit the res. Blowin them only risks damaging them, by drying them out or stressing them, absolutely no benefit. Let them have a couple weeks as the newborns they are.
Right but you said yourself roots don't like light. On the off-chance the seed cracks in such a way that the tap root is initially exposed to light before it orients itself properly, I feel like plugging the hole is good insurance.
If the rr hole is so big that light can get in, the plug won’t hurt. I usually turn my rr’s flatside (top) down, slit the top 1/4-1/2 inch deep, push in my seed, slap on the dome and wait for cotyledon/tap root. If the slit doesn't close tightly, i plug it, mainly to preserve humidity. Roots have evolved without light, so they don’t use it. So why expose them, when the light will dramatically increase bad microbe populations in nute soup? But the little received by new seedlings does nada,

I have read about others using this method, the RR sits more stable with the large portion at the bottom and apparently does it's job just as well. I think next time I will try that. My cabinet has 8 pots and I will only be using 2 or 3 of them for plants. Will the 200 watt CFL shine through the 5 empty pots and negatively affect the roots of the plants in the other 3 pots, since roots do not like light? If so, what would I need to do to effectively block light in the 5 unused pots?
