Grow tent 600w hps hydro under construction

Hey there I think your setup is tight. In my opinion you drawing air in through the flaps at the bottom via negative pressure for your fan will only work if you have alot of fresh, cool air in that room perhaps from a window. Otherwise just bringing in that house-warm slightly stale air won't quite cut it for proper ventilation. You may need to draw fresh air directly into your room from an outside source, whatever that may take. Try your plan and if it works and the plants are healthy and thriving...stick to it my friend, no need for further measures. I also think that you should sell your hydro system , buy some 3 gallon pots, fillem' with wicked soil medium and grow some nice 5 footers I just like soil growing better

10 oz 22 gr dried. now for curing.

Hey good job on the grow. Hope I make it ....Im 2 weeks in to 12/12

I got pretty much the same setup as you....Growing some gods gift. 4x4 tent 600w with carbon filter. DWC 5 gal x2 I have the hortilux eye and am going with botanicare nutes. With Kool Bloom.

My foliar canopy is 3x4.....lighter size pistol balls on em.

Funny thing is I am using DWC in 5 gal buckets with central res......and I had some similar problems to you. I think I got some root rot starting. THe leaves are turning yellow and the ppm in one bucket keeps going up. EC x500. 1100 base going up to about 1300 within 3-4 days.
Any advice you could give?

Im going with the tray next grow and "hope" its a good one.

I was thinking i might get like 6 oz off these two.....

great post. I am building a similar set up.
I see a lot of people have said that they are building simial set ups too.
i got a next gen 400w/600w mh /hps ballist.
i got a xtrasun 6 air cooled reflector.
I built a bubble ponics system.
I am worried about the smell. i live in a 1 bedroom apt.
let me know how the filter is working. I was going to build one but i might buy the same one you got if you give it a good review.
I am trying to decide on seeds now.
where to get them and wht type. I hear that the auto flowering plants do well for indoor grows where odor is an issue. However, i wanted to grow some jack the ripper
letme know what you decide.
also what are you doing for humidity? have you had to make any adjustments etc.

Humidity was ok, the only problem was the carbon filter was too heavy for my tent, so go with a lighter filter, or an ozone generator.

Hey how you looking on those pics???

incase you havent figured it out or someone hasnt said it yet you should make sure that your tent is completely light proof.. like no light shining thru the zippers!

Yeah, light shines through my zippers too, and at first I guess I was a little concerned, but I hopped in the tent and turned the lights on outside and it was still dark as shit in there.

Light doesn't really SHINE through the zippers it just kind of illuminates the zipper cloth and the ambient light in my space doesn't penetrate it nearly as well as the HPS penetrates it coming out.

The sun huts are pretty tight, but I am still partial to grolabs if u have the $.

My only complaint about the GrowLAB is height. The Sun Hut (I think) is 6" taller. That 6" could be a big difference right now in my garden.
