First HPS Grow - 600w - Multiple Strains - Closest

Hello RIU members. I am finally starting my first HPS grow, moving from CFLs, and I'm stoked. I just put four seeds I had in the soil today, I haven't ordered anything yet so I don't know "for sure" strains but two are completely unknown and two are suppose to be True Blueberry. I am kind of jumping the gun so the setup isn't the cleanest and I am going doing what I can when I can. I have one 6in fan with ducting to my cooltube light taking air out. I currently dont have an intake duct due to the fact that I don't know where I can put it in my closest, and I obviously can't put it on the same wall where my exhaust is. The room temp is 75f day and 68f night. I just measure the temperature near the pots and it was up to 86, I also had the light about 13in away. I moved it up to around 16-17in and added a small floor fan to hopefully lower the temperature. I'll be using small 4in pots then moving up to 2 gallon smart pots and possibly finishing in 5 gallon pots depending on size and amount of plants. Don't have veg nutes so I'm depending on natural nutrients during veg. I do got Advanced Nutes for flowering. I think that's pretty much it, I'll be posting pictures of the setup soon. Please let me know your thoughts and if I'm doing this right or wrong, because all I can do is learn. Peace n Love, Ben

Will be watching your journey! good luck=)

Thanks man, really excited to see the results compared to CFLs.

Here are a few pictures of my setup, real simple to me. Space I'm working with is 25" deep x 95" long x 84" tall.

you will be blown away by the difference. its night and day. nice to see youve made the switch. youll never go back

just a thought id dim them lights 600watts on brand new sprouts is a lil much id let them grow a few sets of true leaves brfore putting them in full 600 watt hps id maybe go window sill for a week or maybe some cfl's to get her going you know. just my .02 bro take it for what its worth

Alright bud I'll see what I can do about dimming the lights. Look into it.

I cant tell for sure, but is that your digital ballest INSIDE the grow room? If so, I highly recomend moving it OUTSIDE of your tent/cab. You dont want to risk it getting wet/humid and more importantly, it will give out quite a bit if heat.

Other then that, looks to be a great setup. Good luck with your journy

Yeah I didn't even really think about it since I just put the seeds in today. I can easily get it out of there into another room. I did notice how hot they got so I have it on a metal sheet as of right now. Thanks though I can't wait for the results in 3-4 months haha.

I would take it ASAP! Idk that sitting it on a metal sheet is also a great idea either. I have mine on a wooden shelf, and i cut a rubber mud flap to fit the shelf and I have it sitting on that. Can never be to carfull you know.

Im not trying to be a dick, i am just lookin out, u know?!

I gotcha gotta move the ballast haha. I'll be right on it no doubt.

Well this thread might be over before it ever got a good start. Without being able to put an intake in the closest and not being able to afford an a/c unit I cannot get it cooler then 86f. I am going to try one more thing but if it doesn't work then I am just going to have to wait.

Why don't you veg them with your CFL's and by the time you get to flowering switch to your HPS? By then maybe you'll have proper intake??
Check out my grow in my sig, I vegged that baby with CFLs and just now switched while flowering.

The thing was my CFL cab I made didn't have intake or exhaust so they were also in around the same heat and didn't seem to do great, but I was running 68w cfls which seem a lot hotter then 42w cfls. My plan in the long run is to veg with cfls in a small cab with clones and flower with the hps but I'm trying to get one running well and my HPS light has been sitting for a long time so I want to use it. Blah blah blah, most of these excuses are just because of money pretty much.

DONT quit now! Everything is lookin great! There is always away to "farm job" your setup! Lol... Why is it you think tgat you can not put an intake/exhaust in?

I have an 6in exhaust fan on my cooltube it's the fact that it wouldn't lower my temperatures from 86f, and how my closest is setup the other three walls or the ceiling that you would go to for intake cannot be used. Obviously didn't think about this problem before hand. A buddy of mine said that as long as it doesn't rise from that I should still be fine and still possibly pull off my set goal, but that's also with a veg came running. So I am going to keep truckin' with what I got and see what happens.

Why cant you put an intake in the closet door? Ant y couldnt u use the 3 walls (just curious)?

Btw, 86 is doable if you have good circulation, problem is that you are already tipping the high end.

Yeah I was told people go higher with success so I'm not too worried and getting another floor fan won't be an issue. The reason why I can't use the ceiling is because the space above it leads into the room I exhaust into. The reason I can't use the one of the three walls is because its concrete, the other two walls and closest door would lead into my room which would be obvious what I got going on to others. It's not completely stealth but I needs to be stealth enough so you would have to open a few doors to find you know.

I say keep on truckin brotha.. I'm fighting 88-91f temps right now till I get a better hood but my girls are doing great.
