Hey i was wondering how the temprature in your grow room effects the plant, i have read that it should be between 60-75 degrees but i think this might be a bit hard to maintain as i cant afford the heating. Ive got both the red and blue specrum CFL lights fertaliers ect but its a little impractical having to buy and wire up a heater with a thermostat how badly will the quality of my bud be compramised if is a bit colder? bare in mind im in the UK and its pretty grim over here

I got some pretty expensive seeds like £100 a pack seeds ( Super Silver Haze, White Widow X Big Bud, Medijuana, Strawberry Ice, Purple Power and some others) your help would be much appreciated.:bigjoint: Also whats the deal with humidaty.

I would add more cfls or higher output clfs (more light equals more bud and more heat) Hope this helps

Lumens is the brightness of a light source. This is why people use MH bulbs and HPS bulbs because they can have a greater source of Lumens per bulb then yours and mine CFL bulbs but the down size it high heat production and cost in electricity and cost per bulb.

I see, thats on eof the reaons i bought the CFL's and the fact tha you can plug them into a normal light socket which i can wire up myself no problem.


Back tot he original Question how much does a low temprature (in a cupboard with 2 CFL) compramise the quality of the bud combined with a low humidaty?

Humidity first is a easy fix just put a glass of water in the cupboard as for heat that was fore mentioned (more CFLs). Most botanists say that low temp 60 degrees stunt plants stem elongation and fruiting mass, cannabis plants are tolerant to low temps but 70-88 are completely fine. if u want more lights for heat and dencer bigger buds and you only have the 2 socket outlets get those y light fixtures then u can double the light outlets. http://base1.googlehosted.com/base_media?q=http://ecx.images-amazon.com/images/I/41b5waTHo2L._SL500_AA280_.jpg&size=18&dhm=4ad387fc&hl=en

Its really hard to say, it grows best between about 70 and 80 degrees F, or 21 to 27 degrees C. Some strains are hardier, and will do better than others in the cold. As Love1Fear suggested, you should add more lights instead of a heater if that will do the trick. Your yeild will be miniscule if you only use 2 to 4 CFL's for 4 to 5 plants. They're going to need a ton more light than that when flowering.

How big is the cupboard or u can add lights till desired temp. You can buy a Hygrometer (measures moisture in air) if you are willing to buy one of these devices I would get a combo unit that has a thermometer/Hygrometer around 20 bucks total at a hardware store or even try a Walmart.

The answer to your question will low temps in the 60's affect my buds

YES, that temp is to low needs to be no more than 75 and no less than 70

however a 10 degree drop at night (lights out) is acceptable

talking in F not C

you MUST know the humidity as a good grow is the sum of all of the parts and humidity is a part as is light and temp

all of you should read my NooB Advice thread

5 degree difference is way too over dramatic if that was true, which is is not the cannabis plant that occurs in nature would be absent.

giving you the optimum temp for flowering

MJ is temp tolerant from 50F to 90F

it's all in my class

unfortunatly not as i havnt set it up yet as im still waiting on the £416 worth of seeds to come through but when i set it up il post some pics up and we dont ahve a walmart over here and unfortunatly anything like that is rediculously expensive but i suppose its worth it. But realy is it 100% nessicary as the first lot im growing is purple power that was desinged to be grown outdoors in holland. Also ive read that you shouldnt line it with tin foil i was thinking would it be ok to put mirrors all around the plants or would it crisp em up do ya think?

Tinfoil is fine to use my first 2 grows used tinfoil i just used the dull side facing the plants because the shinny side can create hot spots and potentially burn plants.

As for the hygrometer being a critical part of your grow the answers no, if its too humid in the grow area the plants will get willty and you would b able to feel the moisture when u put your hand in the grow room, if that happens remove your glass of water in room and replace with a fizzy drink bottle cap of water.
