My 300w CFL no longer works. When first switched on, I get clicking and the bulb flickers from one or two of the filaments. After 5 seconds or so, the flickering ceases and the clicking stops. I need to know whether to order a new bulb or a new reflector/ballast combo. Any ideas which is...

I am currently running a 300w dual spectrum envirolight and would like to upgrade to a 400w HPS. I am a little concerned however as I have heard that the HPS lights kick out a lot more heat than the CFLs. My grow space is around 1.5ft x 3ft x 4.5ft but the ventilation is a little lacking at...

I've been growing for a year or so using autos under a 300w (true wattage) dual spectrum CFL. Recently I was sent a few freebie seeds but after planting realised these were true cannabis strains, not automatics. Anyway, all is going well, I changed to 12/12 about three weeks in and the plant...

This is my fourth CFL closet grow and as ever i'm using autos. The larger plant is an Automatic Haze (around 5 - 6 weeks old) and the smaller a Blue Mystic (about 4 - 5). The plants are kept in a large cupboard under a 300watt CFL and reflector with two medium fans for ventilation. I am...

I'm currently using a 300 watt CFL (the big envirolight type) and have just finished growing a 60 day wonder in my closet. The results were not as good as we were hoping for as the lower buds were very underdeveloped, probably due to lack of light penetration from the CFL. I am thinking of...

I'm currently running a huge 300w dual spectrum CFL and reflector but for my second grow I want to invest in a couple of small side lights, something in the region of 20w cfls. Can anyone recommend me a good UK retailer where I can purchase the lights and power cables/sockets? My last plant...

Im currently running a huge 300w (true wattage) dual spectrum CFL in a reflector but it's quite apparent that my lower buds are not getting enough light. I'm considering adding some small CFLs as side lighting so would like to know the best place to buy the holders. Can anyone give me a rough...

I have a large closet space with a footprint of around 2.5 square feet and a height of around 3 feet. The walls are painted bright white for reflectivity. I have a single dual spectrum 300W CFL under a reflector that can be raised and lowered as necessary. My question is, how many...

Can I use a standard cheap mechanical timer with a 300w CFL? I know that special equipment is needed for HPS timers but not sure about CFLs. I know to look for a mechanical one rather than electronic or digital but would this be safe to use?

Just bought one of these and a little concerned that it is getting quite warm and also makes a faint hum. Is this normal? Anyone got any photos of grows completed with these lights so I can get an idea of what it is capable of?

My plant is now 3 weeks old so I think it's time to invest in some nutrients. Can anyone recommend a readily available product that I can collect from B&Q or Tesco etc. This is just an experimental window sill grow so I'm not looking at splashing out on specialist products until I get my grow...

Just got my 60 day wonder and have placed it about quarter of an inch under the surface of some light potting soil with the pointed part of the seed facing up. I have moistened the soil and will leave for a few days, regularly remoistening the soil. My question is, is it wrong to germinate in...

Finding it increasingly difficult to score weed so the time has come to try an experimental first time grow. An 8th will last me a month so I'm only looking to grow a very small amount for purely personal consumption (3g would be fine). I understand that window growing is possible here in the...
