Do you think it had anything to do with the crowded cab, or a humidity issue? Great thread! 12/12 all day! peace...bongwaterlost my cheese to bud rot.......some pics......of 1 of my old bubblebombs........cant load any new pics cause loader aint working at mo..
I use HPS from the startIm wondering for those who use Mh and Hps, when do you switch to
the Hps? As soon as sex shows or a week or two after?
i would like to know the same thing.Quick question, has anyone gone from CFL to HPS and stayed in the same grow space? If so, could you tell me what the temperature increase was? I am looking into getting a 250w HPS but have a limit on what I can do in terms of temperature control.

I ran a 250 for a year or so. How many CFL watts are you running? from how many bulbs? What is the room temp now?
As I'm currently an led gardener I can say you'll still be fighting a heat battle but in keeping it warm,On the subject of lighting, I just ordered a 18 watt 660nm red led unit, they are DIY and made up of 6 x 3w leds mounted to alu board and have a power driver, you need to change the lenses to suit your grow area, fix a heatsink and apply 12v power and its complete for about £30, I am going to take out 2 x 35 watt 2700k cfl with each of these kits added and of course replace the 6500k cfl's with 460nm led units. This should save 52 watts of power for the same appx yield per watt (cfl 5w per g/led 1w per g?)
The reason for this is the heat that my 12 cfl bulbs make is just right at the moment (26C) but as the summer comes it will definitely be too hot for growing anything...also the mess of cables will not be missed.
I'm in a cab in my bedroom, fully stealthy until the Ona block runs out lol, perhaps a mix of CFL/LED would help heat for me, it's always 21 degC in the room until summer then it can be 28!!As I'm currently an led gardener I can say you'll still be fighting a heat battle but in keeping it warm,
I previously used 125w cfls and can see a change in yields and power consumption but during the winter months I have to run a small oil filled rad to keep them toasty, I'm also in the uk and the tents in an insulated loft with a duvet thrown over the top,
LEDs for ME are perfect and I wouldn't change, yields are better and the nugs are more compact.
Good luck mate and welcome to farming on Pluto
I currently have a 200w 2700k CFL hanging above the plants and three 30w(117w equivalent) 2700k around the lower part of the 3 plants. My temperatures are in the mid 80's during lights on, low-mid 70's during lights off.
I also have a 16 inch fan for circulation on speed 1 but it can go up 2 more speeds if that would help with temperatures.
Edit: What it is that I intend to do, is use a 250w HPS and 4-5 low wattage 6400k dotted around the plants. The 200w CFL I am using doesn't give enough penetration for my liking, I guess I could just use more smaller CFL's but it's just hassle having to move so many around for adjustments etc.
Maybe I could try scrogging with my next lot of plants, but given I much prefer to go 12/12 from seed, I'm not sure if it's possible to do.
