Would anyone be interested in participating in an auto grow thread?

So...I have always heard negative pressure in a grow tent is a good thing. Then I was doing some reading and found this site called "Indica Institute". The guy writing the article said something pretty distressing.

"Possibly the worst case scenario from this situation is that an inline fan that is too powerful for the size tent you have will create ‘negative air’ in the tent, meaning that air is being pumped out faster than it is coming in, creating a vacuum where the plants are basically being suffocated from lack of air and oxygen."

According to this "expert", everyone on RUI that has set up a ventilation system that pulls negative pressure in their tent is killing their plants from "suffocation"? Does this sound like hooker spit to anyone else? Or have we all be murdering our plants without knowing it?

Negative air pressure in a tent isn't the same as a vacuum. I wouldn't be too concerned with a little negative pressure... There is still lots of air in that tent.

That's the idea we've all been operating off of. A vacuum would be ZERO air. Haha

I'm just shocked that someone writing articles for a website like that could be so lost. Poor fella

"Its negative pressure, so the plant cant breath!!!"

Haha. Insane.

I did enjoy most of his videos though. I have watched several of them

Due to the recent education I received when being beaten into the dirt by oppressive humidity, I have decided to take a few precautions for when the real "Double Grape" grow starts...

There is no room in my 2x4 tent for a dehumidifier or a wall mounted oscillating fan (although I have thought about hanging one upside down from a corner and that might be possible...) and the tent is in a garage. So here is my plan.
1. I added a gun safe dehumidifier above the light, and am getting 2 or 3 of those basement silica canisters to put around the plants.
2. I got 2 of those plant caddy things. Wheel bases that collect the runoff in a container under the plant. This way I can eliminate the maximum amount of water that the plant isnt using without feeding the plants outside the tent (which wont be an option soon into their life due to the SCROG plan)
3. I got one of those "turbo" air circulation fans to put under the plants facing up and at an angle. Like the Vornado 533. That plus a few 6inch clip fans, and the 351cfm inline that is running, will hopefully be enough to keep things moving in there.

Sweet baby James, humidity is brutal to try and manage in a garage tent in the summer.

Update... 4 of 5 BD's germinated and above ground. The 1 that didn't germ I put in a solo just in case

As for the GSC, FastBuds should change their name to FastDuds. Only 1 germ out of 5, 4 are dead, dead, dead. Four dead in ohio...

Worse thing is the GSC was for my wife, at least I got one right...?? After the BD's broke ground, still no sign of the GSC. Next day I dug it out and the seed was unchanged in size, but there looked like "bad spots" on the root. Now I'm bugging, this bitch is goin teats up on me. I put some rooting powder on it and put it in a 1/4" compost and we'll see what happens.

The seeds I got on the FastBuds promo 2 for 1. The 2 packs came lashed together with FastBuds Tape, which ruins the breeder pack when you remove it. Now I'm wondering if the "10 Year Anniv Promo" included 10 year old seeds. What just cleaning out inventory?

I would never pay FastBuds $10 seed full price for 50% germination. Granted I probably got a bad pack, but they lashed it together with the other pack and shipped it out. Hopefully the remaining pack is better. I'm pissed for the wasted time.

Of course I have 9 pots filled, I was anticipating 90% germ rate, lol. Now there's a vacancy, maybe do some transitional or clone stuff in the empty space.

Mephisto Grapey Walter at 6 or so weeks.

May be the best smelling pot plant ever for me. I just want to eat that grape luscious yum.

Grapey Walter, when its finished really well, is one of the best looking plants of any kind I've ever seen.

I have already started a Double Grape grow. 2 of them in a 2x4 tent under a HLG 260 R-spec. Cant wait to see them flower. Double Grape is supposed to be something pretty special according to the boys over on AFN.

Mephisto is king-shit for Auto genetics right now. They are killing it.

Update on the Northern Light Blue, day 18 from sprout. Currently still under a Mars hydro 300 and a 40 led screw in bulb. I'm about to order a HLG 100. She's starting to branch out and pistils started showing today. Does she seem small?

Are you in soil? They grow slower. In coco i have 4 full and either just starting 5th node or full 5th node by 21 days when healthy. If in coco she should be a bit bigger. Still looks good though.

Yeah I'm using soil. I've had heat problems so I'm hoping the new light will help that. I'm getting a cool mist humidifier to hopefully help out until then

Well soil is a slow grower so you're fine. Shes not behind in a bad way is what im saying. What size pots are they in? For soil(which i don't grow in) I'd use 5 or 7 gal pots. Coco, 2-3 is plenty good enough.

Well that is it for me. I am done growing outside. I am sure the constant rain has something to do with this but this is the first time I have ever had snails and slugs eating my plants... But they have just about completely destroyed my northern lights autos... IMG_20190619_171845.jpg IMG_20190619_171903.jpg IMG_20190619_171852.jpg

From now on, I'm only growing indoors. I can't deal with watching these slimy little bastards destroy all my hard work...
That sucks. I would grow outside if legal here but still in coco and keep them on concrete/pourch/deck or whatever. I would hate seeing pests and creatures devouring them.

You try sear hing for anything to combat them as well as other pests? Maybe sand on top of soil could help. Helps with other pests from laying eggs and shit since they can't live off it like the soil underneath.

Man...that's a f'ing bummer. Sorry bro. I had some massacres like in my first season. Took me 2 or 3 seasons to get dialed in. And even then, nature throws crazy curve balls at you. Some of which you cant avoid or prevent or repair. It can be brutal for sure.

I think, like Matty said, location might be a consideration. It looks like where your plants are now have a lot of other vegetation around them and touching the pot. If I was forced to resurrect my love for growing outdoors (like after last year when I almost lost everything) I'd probably focus on growing photos, and in a more secure location. Maybe a raised bed, or on a sand patch, or a patio or concrete pad.

Either way, sorry for what happened. That sucks. We've all been there, so I feel your pain man. On the bright side, if you ever do decide to brave the outdoors again, you'll be armed with some serious knowledge. Location, preemptive pest precautions, and anything else you learned this time around. And if not, you can kill it indoors!

I live in the PNW and slugs grow to the size of cars..lol..
Slug go pellets work well. Copper wire also works.

Bet those plants are fine once the weather pattern changes.

(Sorry I despise indoor growing, and love sun grown..)
What do you do with the copper wire?

I have grown outdoors before and never had slug or snails. I have managed to avoid the other problems I have encountered before. I thought I was going to be good this year... And now half of my autos look like this. My 4 photos look fine. But I have grown them before. My autos were going to be my variety and now idk if I'll get to finish any of them.
