haha... i was going to say EXACTLY what jakezking and justanotherbozo just said...

- if the roots aren;t tangled already, if you wait until the plants are appearing to be root bound or that they are fighting... it will be far far far too late to seperate them - more than likely you will cause some severe root damage trying to untangle them... many of the roots can very very thin like the hair on your head - but not nearly as strong as your hair and can be damaged quite easily.


- the halogen is probably doing absolutly nothing for you.. i;m not sure about the specs on the bulb you are using, but everything i've read seems to point to halogens being useless for growing

also the floro you are using 10k colour temp? i;m not certain thats doing anything either, i;m not sure cannabis can make use of anything in that colour spectrum, may want to consider swapping the bulb out for a T5 bulb if you can find it... though i;m not sure if T5s come in 18".. if i recall... T5s tend to come in non-standard sizes.


I think you'll find the CFLs you've added though should make a fairly dramatic difference... its still not very much light with just 2 of them, but it is MILES ahead of what you had before.

make sure you keep the CFL bulbs roughly 2 inchs away from the top of the plant - probably no more than say 4" and no less than 1" once you go past 4" you are going to have alot of wasted light due to the way CFLs emit their light, and once you are closer than 1" you start running the risk of scorching the leafs.

you can also make some home-made reflectors for your CFLs that you might find will help alot - checkout this article, it has some great info in it - Text

good luck!
