bulb

So while I have some growing experience, it's been a while and I've never grown from seed. I had a few laying around and was bored, so I decided to see what i can or can't do. I literally have no budget for this, just a couple of bucks here and there. So the challenge is to use whatever I can...

Hi guys, can anyone tell me if I need a special type of light socket to run a 400v bulb and ballast or can I use my usual reflector?

Yo yo, I was told that measuring the temperature of your grow directly in the light doesn't give a true reading so now I always measure on the edge of a shadey spot. However I have no real ideas if this is even true and if it is does anyone know why? As the leaves and buds are directly in...

Hi guys. I am relatively new to growing. Have about 5 Indoor and 2 outdoor grows under my belt. My question is about my lights. When I upgraded to a huge air cooled hood. Barely fits in my 3.5x3.5 tent. I modified it to run dual bulbs with two separate ballistis. It's works great...

Evening guys. I'm looking for a bulb that would let me add some light to the lowest parts of my growbox, so the lower tops may yield better. And I found this bulb. My tent is 40cm x 40cm x 120cm (or 1.31 feet x 1.31 feet x 3.93 feet). Here is one of the recent pics And now that I...

I have an extra 600W ballast and hood sitting around that I want to add into my grow room. I need to buy a bulb for it as I only have a spare 400w hps. I am curious is my ballast able to operate a cmh bulb, and if so what kind would I need? I was at my hydro store today and I was told that there...

My previous grow was quite poor. This time I nailed my temp 78F, humidity 55-70%, and ph 5.8-6 in coco and perlite. I'm using a 4 bulb T5 with 3 bulbs 3000K and 1 bulb 6000K. I stuck another 6000K portable bulb a week ago to help out a little. Using around 500ppm on the florabloom nutrient...

I have a 400-watt HPS bulb around here somewhere. It was only used for a relatively short time (I'd estimate less than 200 hours - but certainly less than 400). At that point, I shut down and packed it away. That was several years ago. Can I reasonably expect this bulb to perform as well as it...

But if you had a 600w dimmable ballast (660/600/400/250) and had a 600w hps bulb installed but dimmed to 400w would this bulb run hotter than a 400w if installed and on the same setting ?

Hi guys, stupid question but I've just noticed one of the bulbs in my T5 Lightwave has stopped working. Is it safe for the faulty bulb to remain in situ or is that a fire hazard? It's 2am and I won't be able to sleep not knowing if I need to remove it or not! Any help would be much...

I just purchased a used Lumatek 1000LK ballast on an auction website. This is the non-air cooled kind. However, every bulb I've tried to fire up has only flashed for about 1/2 a second, then no light emitting from the bulb, till around 1-3 minutes later, and another flash, repeatedly. The...
