cmh

High all. First post. About 15 years ago me and my roommate tried to grow some Super Lemon Haze in our small apartment's sauna. I had a small veg CFL cabinet in my bedroom and the flowering was done in the sauna with a 400w HPS with no ventilation or carbon scrubber, just a table fan. We had...

I just (hopefully) upgraded my room with 6 Gavita Pro 600se cmh fixtures each one has two 315w Philips cmh bulbs the literature that came with the fixtures calls for a 100 hour burn in time. This seems excessive to have to run the lights for 100 hours straight for them to burn in correctly...

Well I finally have some pics to share so here are my ongoing grows. I doubt I'll be consistent at posting or very good at producing wild great crops but I will share what I can I guess. I'll start with some pics from my last crop which did not turn out very good. Full on seeded out crop where...

Hi, I want to switch from an HSP 400W to CMH 315W for my 0.8m x 0.8m x 1.6m tent. There for I was planned to use a Philips Greenpower 930 Agro bulb. Now I came across the following nice set, for a nice price: DimLux Expert Series 315W Full Spectrum According to the description, this set comes...

Currently I am using 400W HSP in a 0.80 x 0.80 x 1.60 m (approx. 2.6 x 2.6 x 5 ft) tent. But I want to switch to CMH/CDM/LEC. After a lot of reading, I decided to start with a Philips 315W 930 Agro for veg. and flower. But I need help to find the right one. Suppliers simply use the same terms...

Hey 420, how's it going? Well, after a long and successful grow (I say this before it's fully cured), I'm going to get things going again for the next crop. I learned a lot from my last grow, mainly that I didn't utilize my scrog properly. There were also suggestions for super cropping but I'm...

Hey there, long time creeper first time growing indoors. It's finally legal here in Canada and the wife okay'd the tent so I ran with it. I started from seed, germinating on November 19th, 2018. I'm fortunate to have a good friend who works in a hydroponics shop, so they've been pointing me in...

How can one tell if a CMH bulb is burnt out? During a storm our power slipped on and off a few times and when it came back on my ceramic light wouldn't work. Now question is, is it the bulb or the ballast?
