The 4x4 Grow Tent Club

Hello everyone. Im on my first grow almost to the second week of flower cycle. Im in a 4x4 tent with the virgin v3 led light. My question is should i be cropping this late and is there anything i can do to increase yeilds? If I knew how to upload pics from my phone I would lol

Do I need to compensate for negative pressure? I will be running an air cooled 1000 wt running through a charcoal filter. Couple oscillating fans inside but nothing to bring air back in. Wondering if it will be fine with just a single exhaust
 
I think you will have some heat problems unless your room is 70 degrees or below. Also with that long a veg you may run into height issues if you aren't training. A dimmable ballast will let you try 1000 watts and if it is too much you can simply dial it down.
 
Hi,

I am thinking of adding a 4x4 or a 5x5 tent to my room. I will be planning on using it for flowering 4 plants, but at a staggered start. I will put 2 plants in, and then add 2 more after 4 weeks. When the first 2 are harvested, 2 more will go in. I am thinking of using either 2x600 watt bulbs or a single 1000 watt bulb. I will have a portable ac unit in the main room that the tent is in. Air will be vented out of the room. There will also be a cabinet running a 400 watt mh bulb.

What do y'all think about this setup? I originally thought two bulbs is better since I could have one closer to the shorter plants. But I fear that this won't work as it will be too close to the taller plants. I envision the plants starting off at about 9-12" of vertical growth using a flux technique before putting them in 12-12. I figure they will end up at 18-24" of vertical growth when the stretch is done. The hoods would be air cooled for what it's worth.
 
I use a 1000w hps in my 4x4 an find it perfect other then the heat, n even in a 5x5 ur Gona need a good extraction fan. Vent it outside if at all possible to reduce a/c use. I vented mine into the room an was hitting 90+ even with the a/c unit inside the tent. Other then that it works great. U could even go 3-4 plants at a time if u wanted

Oh an build a lil bench for the newer plants so they r raised up closer to the light

I tried with 1000w setting and was hitting 90 very quick. I then tried 600 watt setting and didn't do too much better. I installed an oscillating fan in the tent and now I can sit at 86 degrees with 600 watts no problem. I think I will be able to run the 4x4 tent at 600 watts and then the 2x3 cabinet at 300 watts. This allows me to be safe on one circuit and be ok. The AC was a bust and is too big a draw for my breaker. Now I suppose I have a delema. should I keep the 1000 watt ballast and just use it at 600 watts for now, or should I return it for a 600 watt ballast?
 
Welcome my friends and fellow growers to the show!

After an accidental, decent last grow, two plants,15+ zips, and decent quality, am back with my original plan for last fall. Will be doing a 5 plant vertical grow with coco, screens, and stacked 315 W CMH (3100 K) and drip irrigation.

Grow area - 4x4x6'7" Gorilla tent
Lights — 2 x Nanolux 315W CMH NA
Screens - 21"x 40" Overall working height is 54" (137 cm)
Pots— Two gallon Smart Pots
Medium - Straight Coco
Nutes — Canna Coco A&B, Rhizotonic, Cannazym, Boost and KoolBloom.
Number of plants — 5
Strain — Barneys Farm G13 Haze (4), and Critical Kush (1)

The grow:

Seedlings should be replanted into the two gallon smart pots within a week, one of the G13's is behind by about 6 day or so.

The drip irrigation is a 1/2" setup fed by a 3/4" line that originates in a separate room, from a 10 gal primary rez and a secondary 14 gal rez that recirculates the rez's and keep the primary filled. The manifold is 8 stations, but will plug 3 stations. It will have equal length 1/4" feed lines that I am considering attaching a 1/4" cross that will allow three lines to feed each plant. Each main feed line will have a quick disconnect so I can move the plants in and out of the tent as needed to work on them. Will post pics soon of this setup.

I used one of the 315W last grow along with a 400W LED, both hung slightly tilted toward the two plants.
Now this run will be the first time I have run 2 - 315's in a vert grow. I am truly impressed with the 315W for how it responded last grow. Both ballast are outside the tent, have plenty of air movement so I am not that concerned with heat issues, do have extra AC in the small room I am extracting air from, if needed.
Here's a picture of the two fixtures w/o the bulbs.

Will change the height of the lower light stand by removing pvc pipe and replacing with with longer pieces.

l accept comments, both positive and negative, and suggestion from all you very smart people, with more experience than I.

Ok today the Ladies were transplanted from their Solo's to the Smart Pots and have the irrigation setup, tested and ready, less a few tweeks.

Two gallon pots, coco to given level with Solo imbedded to height using 2 cups, one inside the other. This way I can fill the pots, then remove the second cup to have in place a sliced cup for watering in the coco.

The 1st cup with the slits and holes sets in the coco at level, then a solid 2nd cup is place inside the first and the remainder of the coco is put in. Then remove the 2nd solid cup and begin filling the 1st cup with solution, which slowly saturates the coco.

Once saturated, the cup is removed and now they are ready for the transplants. The seedlings growing in Solo's fits directly into the hole shaped like a Solo.

They are in the tent under and SS400 LED and the drip system is in place but needs more dialing in and straightening up the mess of hoses.

Will grow under the under the LED for a week or two then remove the LED and add one of the 315's. When the plants get to the right height the second 315 will be added.

Later,

Complete noob to posting in forums ( been extracting info from them for yrs) and growing. Long time lurker in the shadows and 420 makes me feel right at home, especially when I find out that I qualify for this here club soooo here i go..... Hopefully I'm posting this right

4x4 Apollo Horticulture tent
600w dimmable Apollo air cooled hood
5 gal Root pouches
FFOF soil w/ 35% Perlite
Fox Farm Nutrients Trio
Dolomite Lime (not even sure if i need this, advice?)
 
open the flaps on the bottom of your tent, passive intakes are enough. if you are in flower, you just got to remember to turn fan down, and close flaps during lights off. I have a 2x4 for veg, and run 2 6" lines from it to my 4x4. painted the inside of tubes black, so no light leak between tents. open the flaps on the 2x4, and let all air flow through it to the 4x4 and out.
