The 4x4 Grow Tent Club

Is anyone running 1000 watts and keeping their canopy in the high 70's- very low 80's? My tent is in a basement, so an A/C would be too expensive and a pain, but my peak intake temp. is around 72 degrees- most of the time 68-ish. I'm using a 400 cfm intake and a 400 cfm exhaust; my exhaust goes carbon filter through air-cooled reflector and out, so my intake is running at about 25% power to keep negative pressure, but the air is getting turned over in the tent multiple times a minute. The temp above my light is in the mid-high 70s, but I can't get a 1000 watt to keep the canopy under 86 from 2+ feet away, and I'm at 82 at 2+, which I still don't love, when I dim to 75% power. I have a 12" oscillating fan that stays just under the light as I raise it with the plant and two, 6" oscillating fans moving air around below the canopy. Anybody getting it done without A/C?

I wouldn't worry much until you start hitting the 90s regularly. I run a 1000w hps and an led and stay under 86ish. Negative pressure just like you. Two oscillating fans at ground level and one fan pointed at the space between the light and top of plants. I found this was the best to lower temp with lights on. One of my "intake" ducts is pulling fresh air from the window. My setup is charcoal--fan--duct--light--duct---outside tent to window to dump hot air out. Then I have theee seperate passive intakes. I've played with having a fan on one of the intakes to force air in but didn't notice any benefit

Also, keep the oscillating fan directly level with the space Between lamp and plant and take it off oscillating. Keep the ones on the ground spinning but just have this fan pointed at the gap in between light and plant. Also, are you using a thermometer without a lead that you place or an all in one that sits whenever you put it?
 
Still having an issue with only one of my Astrodawgs. Yellowing and slightly mutated new growth. Any ideas ?

As you can see, it's only affecting certain tops while others are perfectly normal. Please stop my journal for a full debrief.

What is wrong is a side issue at this point. I have the same plants reacting differently to the same feeding. It looks like a deficiency, which means your roots are blocked for that particular mineral. If it is getting worse, you need to flush the soil. Do you know how to do that? If it's not bad, just stick to water for that plant until it visibly improves. Half of my sativas have a manganese deficiency (I think), which seem to be ok enough that they have recovered when there weekly feeding comes around. Don't need to panic, but it won't hurt to flush it either.

Flushing consists of roughly 3 gals of water per gal of soil right ? I did about a month ago and fixed what was happening at the time. Everything has been beautiful until this. Ever since I upped the feed to half strength tho it's been improving. New growth isn't as bad... continue what I'm doing or just plain water til it changes ? I don't think it's serious enough for a flush.... yet !
 
You are probably right. As an inexperienced grower when I see something wrong with a leaf I freak out. I can generally figure out what I did to cause it, but I'm not 100% sure what is wrong. I look at my plants every day, so I think I can catch anything before it's terminal. I'm putting 4 different types of neuts into the water at this stage. I think I'll leave one out and see what happens. Where I live it's turned hot and instead of watering every two or three days, it's down to every one or two. I wasn't really thinking when I started flowering. I should have had the lights on at night when it is cooler.

:420:This is my first grow and I have no friends or anyone to ask for help. This is my first indoor setup. I would like to get some advice on what i am buying. I have grown outdoor but not indoor. Any advice and help is greatly appreciated.

Hi. I'm new to this as well. I have LED lights which I'm very happy with. I'd recommend no more than 4 plants. If it's not legal where you are you need a charcoal filter for the extractor that you will need to buy in any case. I have a 5" for that size tent. You need a PH pen and PHup and PHdown to adjust your water correctly. Soil medium is easiest to grow in. I use Canna Terra pro plus. There are a series of neutrients developed specifically for this grow medium. Whichever medium you choose get the neutrients for it. Get feminized seeds. Autos are probably the easiest to grow. Whatever you get either all autos or not.

Those are the type of things that only take us once to learn from huh ?! I do the same thing lol, I check a few times a day to see any new growth or signs of upcoming danger, isn't that how it's supposed to be lol ? Do u have a journal ? I was thinking of scrogging... looks like I have no choice

Yes. I've kept a journal. I started it when I started flowering and backtracked to germination, so my records are pretty good. I had a bunch of photos to remind me of dates, which I pasted into a word document. I've also got a spreadsheet which I update a couple of times a week. Basically, I note neuts, water, and anything bad. I was going to put it on here, but I thought I'd do the next one over winter instead. I've made SO MANY MISTAKES that it's a bit embarrassing. It really is a miracle that anything is alive.

I'm down to six plants which is noticeable better in the grow room. The last Indica is about a week or two away from harvest, which will allow the sativas proper room for the final couple of weeks. I chopped the first Indica 4 days ago and hung it up to dry in a spare shower room. The smell got stronger the longer it hung. Even with Ona to mask the smell it was noticeable. Possibly a bit paranoid, but peace of mind is important. This morning I took a box and fixed a bamboo pole through it and rehung the branches. It's fairly narrow. I propped it up next to a vent in the grow tent, so it is dark, ventilated, and most importantly for me filtered. The charcoal filter for the extractor is really very good. Hopefully, it will work as well with the drying plant.

This is the indica about a week before I chopped it. I might have done it a bit early, but

a) there are more where that came from
b) I need the space
c) I'm about out of weed
d) see (c)
e) Most of the trichones were cloudy and the flowers were no longer white. They were yellow and covered in THC.

I give clones away when I have excess, just me, i don't sell anything.
Last I was in a rec dispensary I saw clones for $15 to $25.
i have 14 G13 Haze and 5 Critical Kush clones that are being picked up this week. They are four weeks from the cuts, 12 inches tall and doing fine.
I give them to a group of ex-GI's who suffer from PTSD, I also make Cannabis Oil with any excess cannabis I have and they get that also. Being a Nam vet I know what they are going through, I talk with them, try and give some comfort and the cannabis and CO help them a lot.

Got them crossed!! I'm right there too...Thanks for the example of plants ready to go!

Mine are not all sexed (been staring at pre-flowers for days because one of the larger plants decided to show female sex loud and clear at about 40 days from seed, I've been waiting to flip hoping they would tell me something good! If too many men I will have to fatten up the ladies...I just said that).

Maybe i'm dragging my feet but based on your canopy I should start thinking about flipping soon...
