But to ignore vpd completely will lead to new growers who start question why their plant isn't as vigorous or doesnt veg as fast. This kind of leads us back to the whys over the howsHere's an example of how/why we can simplify things for NGs.
These seeds were under 100% humidity for 5 days. I put them in the rockwool yesterday and left uncovered at 35% humidity. Earlier today it was 39% and a few hours later it crept up into the 40s. Not ideal but do you see a problem?
Now if I was to tell a NG to keep the humidity high, cover them with a dome, the seedling will grow and neglect the roots causing leggy seedlings. Now the NG may have problems with floppy plants, problem with keeping the humidity just right, and now they gotta harden them off. I don't know about you but I hate hardening plants off. It's not hard but if you get caught slipping hardening off isn't so easy, there's a delicate balance there, why put NGs through that? I know what I'm doing and I don't want to mess with any of that stuff ya know? Why burden them?
We can eliminate humidity talk for 90% of NGs and let them know they won't have to worry about humidity till a month into flowering. Nice and easy, set your dehumidifier to 55 on day one (because it's usually close enough to 60 when it kicks on) and forget about it till a month into flowering.
That's how I roll, I don't put effort into humidity till a month into flowering. I know I sound crazy but the proof is in the puddin. How much more extreme can I get with abusing seedlings to get people to understand that humidity isn't that important?
Everywhere I look I see humidity abuse, even humidifiers in tents with fully veggies plants. So much effort and money is spent on humidity cluttering up grow tents with humidity equipment. It's really determental a lot of the times.
I get it tho, humidity, as simple as it is, gets a lot of attention. It's relatively easy, NGs feel accomplished and proud when they get their humidity just right. Kinda like a badge of honor.
It can be very disheartening to watch other growers plants flourish while their's looks "weak"
