Sorry 8. Good to hear from you. Hope its all sorted with your comp. My laptop is my saviour. It goes where i go. Yes it was a very sad day but i think it will be for my long term benefit as i just want a decent smoke and the way it was looking it could be 2049 before i get it right. Anyway its nice to watch others revel while i learn.hey man, i am sorry for your loss. the white rhino will treat you better. ive been mia for a couple of days. broken puter. got a mates now so im back.
Whilst HPS are very good for grow's from start to finish, they give off an insane amount of heat even the 150w HPS give's off big heat, unless a very effective cooling system is used! in a confined space with no venting, fans or cooling of any kind the plants will fry and more importantly a 250w HPS without cooling would be a serious fire hazzard! - STELTHYDitch the cfls, if power consumption or heat is a problem, get a small HPS 250w, use it for both veggin & flowering, Lucragrow have the best bulbs.
Also Use coco & perlite 50/50 mix as a medium.
You will find that if you grow in soil the root mass 9 times out of 10, will end up being bigger than the actual plant, reason being exspecialy if the soil is fairly dry, the roots will grow bigger in search of more water and food, starting in big pots is a good idea, you don't have to change them use perlite, this holds in water, a good idea if you forget to water for a day, or so. As far as lighting goes CFL's do work and if used correctly work very well, avoid purple spec as the intensity is neither here nor there, blue spec for veg (6500k) or there abouts, and red spec for flower/budding, (2600k) or there abouts, if money is not a big issue go for "ENVIROGROW" Lights, you can use 1 blue for veg and 1 red for budding, but for optimal performance for vegging use 2 blue 125w/150w ENVIROGROW lights and 1 red 125w/150w ENVIROGROW light, and then after a 48hr period of darkness (when you want to start flowering) swap the lighting to 2 red 125w/150w ENVIROGROW lights and 1 blue 125w/150w ENVIROGROW light, this will allow your ladies to grow under a superb spectrum, 250w & 300w variations are available but you will most definatley need air in/out-takes, I would advise you do this in your cupboard anyway , because drawing in fresh air and pushing out used air is very good to assist plant growth, as well as cooling the grow room temps! you should keep the room at around 26oC give or take a degree, and at around the same maybe a few degrees less for night (lights off), if you hold a thermometer at the canopy level of your plants and the lower you lighting so the downward temps from you light/s is reaching your plants at no more than 25/26 oC, this will be a good distance to keep your lights throughout your grow , for air vents I would use 2x 120mm cpu (computer fan's) install 1 at grow level pull air in, and 1 at the top either on the side or on the actual top sucking air out! if you grow cupboard is air tight, upon turning on the fans will create a negative pressure and force the heat, & (smell once in late veg) out the top, you can use draft excluder sticky foam strips to help you achieve an air tight seal, excluding you newly installed fans, you can wire the 2 fans together once they are in place and use 1 anolog power transformer plug to alternate voltage (speed) of the fans less voltage for slow movement (if you need the room temps to be warmer) and more voltage (speed) if you need the room to be cooler! I ll continue to read your thread and interject more help soon - STELTHYOk agreed that i am off to Bunnings tomorrow. Getting some perlite and coco. I just checked on em and the roots are starting to stick out the bottom of the pot. Time to change? I cant believe it as they are puny plants and the pots are quite big compared to the plants. BBloomer i live pretty close to the city centre so blocks of land are small. I guess i dont want some junkie jumping my fence and destroying a lot of work too. Otherwise would le to have em in my yard. I have bought some CFLs now so i will try and my first smoke before i buy any HID lights. I am sure it will be better buds but lets see what CFLs can do. Thanks for taking the time to reply.
Cfl's are meant for vegging (blue), and side lighting, but that tells you they will bud the sides of your plant! so there is no reason if you re doing a small grow that they wont see you through to a good harvest if used correctly, eith a few good nuitrients , QUOTE:- Also dont transplant too earlier, Its better to be full of roots then transplant rather than transplant too early and the root base fall apart, which does shock your plants for a while, for example u can grow a 1 foot plant in a plastic party cup, I know this from experience, only problem is they drink more often in smaller pots. This is very true, how ever its a good idea to just start in a bigger pot (like the size you want her to stay in till harvest) - STELTHYHonestly I dont know how anybody is even able to grow using cfls, I only use them for lighting clones.

Yep 250w HPS with in and out take fans are a good way to go keep your lights as close as possible, if you do end up with 250w HPS or a 250w CFL ENVIROGROW light a cool-tube, or air cooled reflector is a brilliant idea, they are easy to make too, they keep the temps low in you grow space and allow the plants to actually touch the glass tube/ reflector for maximum light intake! - STELTHYHey rocky try n sack them cfls if you can your growth will explode with a 250w hps, also if u got some spare cash and you are able to cut up your cupboard why dont you put an inlet and exhaust fan in it heat problem semi solved?
If you can keep the fans running as long as you can, and keep them going full time when the lights are on that helps...
Also In my own short experience I have grown fine 35c heat, but I have had temps reach 39c which is too hot.
I can see how they are about to get stretchy for the cfl light, you may wanna start doing some lst otherwise you will end up constantly losing your lower leaves, and you will end up with a tall stalky plant like this pic.
Lst is low stress training, start pulling the branches with string to encourage side growth, instead of vertical growth.
