600 watt too hot but good for sunbathing

[ADIV 3]

.Hello, Ivor the newbie here. I have got a very small grow space (20"*20" *5ft) and not having any disposable income, I am trying to grow 1 plant on the cheap. My problem is that I bought a 600w hps light but it puts my little grow room at 95d great for sunbathing under but not great for my little gorilla cookies plant (free seed with other purchase) so I was wondering if I used a 250w bulb instead, would it make much difference in temperature or should I bite the bullet and buy a Mars Hydro TS1000. As I said I have to do cheap, so in my little cupboard I have covered the walls and door with 2 thermal blankets, a small fan thermostat heater, an extension socket, the plant in the middle in a 1-gallon pot, a cheap led grow light that gives out the dreaded blurple (ebay £20 2 years ago) and 3 small led fish tank lights. The little seedling looks very strong and healthy.

Today arrived an £11 humidifier, the sort that squirts puffs of steam, and it has made humidity go from 40 now on 75 and my temperature with those crap lights is on 25.3. So will a 250 watt bulb still be to hot for my little space?

Thank you

ivor

What do you have for extraction?

opening the door for 10 minutes now and then it is a cupboard with no outside walls and the ceiling is the flat upstairs's concrete floor. we are in a council flat so cutting big holes anywhere is a no-no. it's making me panic a bit because the gorilla cookie plant I am growing is supposed to be very very stinky. I am not worried about the extraction (never had it on 2 previous grows without problems) apart from it helps to cool. because the cupboard is in the bedroom and my missus hates the smell of weed, I may have to buy a £30 fan duct kit from ebay along with carbon filter and sneak it through a slightly open door and put a black out curtain around the door. sorry i've had a couple of spliffs and am now talking silly lol.

i would certainly sort the filter.

 

led is much cooler

I'd stick with the HPS and use the budget on an extraction system.

 

Doesn't matter what light u put in there, without air flow it will just get hotter and hotter. So even if u got an LED, you will still need extraction 100%, getting an LED wont mean you can get away without a fan and filter setup.

 

Even if u buy a cheap 5" setup, as long as air going in comes from outside or a cool area you should be able to keep it "Growable".

 

But 600w in that area is pushing the limits of what a budget extraction system can do, especially given summer is imminent. If this had been December I'd have said your golden for a cheap 4" setup, but I think a 5" will be minimum this time of year.

 

Have some real thoughts before going LED. They are great not a doubt, but will you run into the opposite issue in winter with a light unit that generates no heat? IMO its easier and cheaper to cool a warm area compared to heating a cold one.

+1 on the extraction being your budget filler. Did the same as u wanna, grow came out dog shit

Definitely don't by a Mars Hydro light

 

 

E2a, heating a proper indoor grow ain't a problem with LED in the winter especially in a flat.

@Military Grade what's the beef with mars hydro? 

 

I've got a ts2000 n I'm sure there's better out there but it's done me really well so far

Is the ballast an adjustable one?

 

If not I wouldn’t advise putting a 250W bulb in a 600W fixture.

 

In rented accommodation?

I go through the cupboard door with my ducting,

a replacement door will be easy enough for me to get hold of if I decide I don’t want to just fill the hole before I move out

600w hps in a less than two foot square space is not going to work out well. That's 25000 lumens per foot. iirc 70% of those photons are longwave warm ones that's good for heat but expensive if you have to get rid of it.

 

I concur generally  with Greenvision, but 600w is far too much to deal with in that space.

You say that you want to grow on the cheap but your 600w light is expensive to run and especially for just 1 plant I'm paying 36p and if you run it for 18 hours a day then electric alone is costing you £3.67 and that's nearly £26 a week for veg only and if you get any problems its all just wasted electric good luck growing but it's nit a cheap hobby I'm afraid

Can get better build quality and better par coverage for the same price that's all mate

[catweazle1 4,890]

To add to Grow lady's post: with a 600w light, your on-going light energy cost will be about 400% higher than it needs to be. The trouble with most HIDs is that you can't dim them, so you have to use them on full all of the time. You can raise the light to dim, but it still costs the same.
