Dam heat already messing things up...T-5 grow as plan B

Hear ya, i bought an intake fan and it spun like it was on even when it wasn't and I removed it. I use both a 4x4 T5 and a 600 during much of flower.
Yeah the T-5 120 cm long with 4 tubes are the best..I have 2 of them and 2 of the 8 tube ones,,but the 8 tube ones are not fitting above 4 plants nicely so the best option if I would be going full T-5 for the summer would be to buy 6 more of the 4 tube versions and have
8 of them in total above my 16 plants, I have a smaller tent also with 3 plants and there is a 8 tube T-5 perfect...but even I love to spend serious amount of cash to trying to perfect my grow project,,I have forsed my self to hold my horses until there is a must..so even my grow room would suffer from a visual disbalance it still might be better to keep as many of the 600 hps on as possible and just partially use the T-5's if it gets too hot..

Just my 2cents...in a tent set up where your yield/quality is already low, spend the extra cash on new/used LED's. Less power, no heat, still a touch better than T5's in my experience. If you cant just do a 600-1000w that's plan B.

Btw, 75-80 should be Ok as long as that's a peak not average measure. But no more, like not even 81ish. Cool it down. If it's constant 80 try and use low/high pressure zones to make sure your fans are grabbing cold, and moving out hot more effiecently.

Just spoke with someone about leds..and they do produce heat and can be noisy with their cooling fans rattling...
it would be sweet if they would be the holy grale of growing pot, no heat ,no sound and huge yields..I am all in...

"None" is a relative measure, your right. Relative to my experience with 1000w's. I haven't use LED's with an integrated fan, but when you swap out a 1000w HPS for an LED in a veg room, especially next to a flower room, it sure feels a lot like nothing! But your right, some ain't none. And if "some" is enough, your chapped. I'd take LEDs over T5s personally, if not just for the cool factor and pretty colors.... For veg they are a lot nicer, easier on the eyes, and don't EVER haft to be changed. Eliminating the possibility of dropping and breaking toxic bulbs in your nice clean room, and showering shards of glass and lots of blood all over your veggers...I mean, not that I've done that...more than once.....(sigh)

Well..hmmm.. I am not saying no to LED's ...I am really interested if they would work in flower nicely...and not create heat or noise
Have they made them better recently ? I admit that all I know is hear say haven't really met anybody using them and praise them...
Even I am big spender in buying all kind of things without thinking twice...I really have to take a look in to them carefully...
because they can be higher up than T-5's so they wouldn't be blocking any plants crossfire light from HPS ,,,so meaning there could be both up in the sealing like couple leds couple hps and everybody would get the best of the both worlds,,,

Fuck I just can't get it...I turned 2 HPS off and the temps are still 85.1 degrees with 4 lights they where 86.9...
and I never have had more stronger exhausts than now...maybe the one big space is harder to cool than 2 smaller ones...
and outside its only 42.8 degrees...if the tent door is a bit open then the temps are not changin so bigger intake air hole is not the answer ...mine are the 2 x 160 mm. and yep, they are bended to a swan figure to avoid the light leaking they where straighter earlier....I just cant understand WHY,WHY...WHY !

Hi, I upgraded my grow tent to one big 7.9 x 7.9 x 7.2, before I had 2 half that size (so together same m2) but this new has more height .
Before I was using one in each TD-350 Silent exhausts and fans, it worked ok but not perfect, so i thought if I get one big space and more height and upgrade my exhausts to 2 TD-800 Silents , I would get everything much more in the sweet spot...I am using the same reflectors Sun Systems Irradiator with 600w HPS , so 4 x 600w in my set up with 2 x TD-800 exhausts ,I was pretty sure it would be a whole new ballgame ,,,but DAM not so, the temps outside is only 41 F. and inside my tent its like 86 F. ...shitt fuck..and the grow is just in its first 4 weeks so it finishes around end of july when its really warm outside....and NO there is no change of using aircon unit...I live in an apartment building where there can not be any installed equipment/noise/more electricity usage..
So the only thing comes to my mind is to use T-5 in stead for summer period...
Any ideas ...do I get lame as yield with T-5's ,,,,anyway heat is not going to give any yields either..
Hey bud!!!! I just had a major heat prob with a lot different circumstances, but a friend of mine bought a camping tent portable ac and got his temps dowm

HPS with LED supplementation works alright. The LED spectrum specific stuff is getting way better, but the good stuff is incomparable to the price of t5's. (T5's are cheap) I like the LED for veg. I've seen larger scale LED supplemented light depth and it looked killer.

I do good with t5. It will not be hard like hid grown but it will still be good.

Heat is still an issue for t5. I would say equivalent to hid.

I run 432 watts in a 2x4x6.

I would think you would be better off with hid and air cooled hoods with those fans you got.

If you don't have an AC, that's your ticket. Did not even think About that, I assumed you had one? Do you already have AC? Go bigger if you already got one...

More than 80F = no bueno.

Hahhaa..Ladies an Gentlemen problem solved...temps in check...Numero uno : active air intake (the first in my life)..installed a TD-350 silent intake inlet fan to suck cool air in....now its a whole new ball game...Numero doze : New ballasts dimmable..now I use 2 x 600 HPS on full force ,one adjusted to 400 and one adjusted to 250 (that one can easily be adjusted to 400 or even 600 now)...also filled my water tanks, I do have chillers but to help the chillers I loaded like 8 big bottles half a gallon size in the freezer and use one freezed bottle in each tank to help keeping the temps low even without chillers ,especially night times when my lights are on and people are sleeping..the tanks have also helped to keep the temps down.... my grow tent temps are now 77 degrees !!!

Yeah, air cooled hoods I have of course , and like I mentioned I removed the T-5's and got 1 new ballast adjustable , 1 like that I had already ,,,,so now 2 x non adjustable and 2 x adjustable and that have also helped with the temps ,but the main fix was to make my intake active, before I always have had only passive intakes...

I had good results with HO t5, was pulli g 2 oz per 18-20inch plant. Heat is still juat as much as an issue though sorry to say. My t5 lights now sit in the closet and a 600w hid feds my garden now.

Heat (BTU) per lumen is higher with t-5 as compared to HPS. I'd assume PAR light would be around the same ratio but I'm not sure.

The active intake works like a charm...2 x full power 2x 450 w temps inside 75.2 degrees !...they are still in vegetative state ..
so for flowering I might be able to do 4 x 600 w at least before the sun really comes up in end july, end of my flowering period..
