Do you poke holes in ur seedling dome cups?
Tubington9started grow question 3 years ago
When using plastic cups to dome seedlings (never have so just curious) do you poke holes in the cup for ventilation? I’m aware the point is to help increase humidity during early stages which I’d like, but do they need vent holes?

They don't need humidity domes, they are not rainforest plants!
They need good air exchange to grow properly and a bit of air movement to strengthen the stem.
Humidity domes is an outdated notion from the 1960s when no one knew anything much about cannabis and thought it came out of jungles.
Unfortunately this idea has persisted, needlessly, until the present day.
I have never in close to 40 years, ever grown seedlings in humidity domes and firmly believe they are absolutely not needed.
Only cuttings/clones need humidity domes.

I’ve wondered this also it seems to be very popular , i get that seedlings need humidity but I heaps prefer to use a heat mat with a well draining pot rather than stewing baby root systems in its own juices , I like to draw the roots down looking for that heat and food .

Growing autos in coir potsI am germinating two more Fast Buds seeds. About to finish soaking them. Someone said that it's not recommended to transplant autos. How about those small coir pots? Roots are supposed to grow right through them.
Has anyone had any success growing in them?Setup. Seedling

What should my VPD be for a grand daddy Purple seedling that hasn't developed its cotyledons yet? Currently am hovering around 0.8 to 0.95. Temp around 75/76 F and RH around 68/69%. As far as I understand it, GDP seedlings need the RH to be between 60 and 70 %.Plant. Other

Curling Cotyledons? 2 day old seedlings.I have seedlings in jiffy pellets and am concerned as the cotyledons are curling downwards. I suspect the pellets are too wet right now and am letting them dry out a bit before watering again. I am following AC Infinity's lighting schedule with 100% light 18/6 @ 36 inches.Setup. Seedling

Hi all, first time grower. I've just put my seeds into jiffy pellets. How's everything looking?
I have some of my wife's plants in the tent as well right now. I'm thinking of going 60% at around 24 inches for the first few weeks with this mixed bag. Thoughts?Setup. Seedling
