I run my exhaust 24/7. I may adjust the power level manually depending on the temps. I’m veg I usually keep a screened vent open to bring in fresh air. With the power on low, not much air is coming in with no vents open. More negative pressure than anything if you as me.
I have a heat mat in there now covering the floor to keep the root zone from getting too cool/cold. I don’t worry about humidity. I’m as low as 20% in one tent, and 40% in another. “Swings” are what I’ve noticed will mess with a plant more than being out of ideal vpd range. Some may have different results. I tend to get lucky. Seriously lol
Dr. Bugbee has a wealth of knowledge on plant science & lighting. He is the creator of the apogee light meter/par sensor/ppfd reader that most of the light testers use to create PAR maps.
In veg with new soil. I start in a solo cup, and feed only tap water. 2 weeks later I transplant into new soil, and continue with water only for about 2 weeks before I introduce nutrients. I start with what’s recommended because the plants are already established by this time. Some strains may not like it, so I would recommend starting nutrients half strength if using bottles. Go with what’s recommended on any organics. Most of that needs time to break down so you don’t want to skimp out. Reading the plants is key when it comes to watering.
It’s hard to schedule watering, it’s best to wait til the pots are 80-90% dry using soil. Lifting the pot will help gauge when to water.
Bottled nutes I would go every other watering with a feed. Calmag/epsom/silica supplements on the off days.
I feed heavily with veg nutes during the stretch, and full strength bloom once I see flowers. Plants will eat up the most it seems during that stretch, and if you can’t keep up with them it seems to be a never ending chase to get them back to health.
Thanks got those words man. Means a lot. I have walked face first into many problems, and found out the hard way. I don’t think I’d have it any other way tho. It’s helped me get in tune with a lot.
