hi guys, just recently finish my second grow and was slightly disappointed on yield, just under 35g a plant (dried cured)

first grow ended up with 5 girls finishing (after 4 hermied) and was left with same amount around 35g a plant, i understand the plants had same amount of light 600w shared between them so this probably works out kind of right having the same total yield from 1 600w.

so i was thinking..............................:idea:

ive been running a 1.2 x1.2 x2m tent with a 600watt hps with 4inch extractor temps have been averaging 23-26 with light on.

im getting prepared for my next grow and was wanting to put in another light eg. 2 x 600watt hps and upgrading to a 6inch ruck extractor fant and using my current 4inch fan as an intake to control temps.

obviously i know by doubling the watts/lumens etc from 600w to 1200w and keeping the same number of plants 9 will increase yield. i was just looking for any advice on keeping the temps in range will upgrading to a 6inch ruck fan fit the bill?

p.s. im in uk so normally dont have a problem with temps

How much is your elect.bill with this type of lighting ?

my last electricity bill was £130 a quarter that was excluding the rest of the households usage tho so i guess around £30-35 a month to run the one 600watt hps a 4inch extractor fan and two 6inch oscillating desk type fans inside the tent for air circulation, im guna estimate by adding another 600watt and upgrading the fans itll be sumthing like £65 a month?

take into account tho the cost above are an average over the growing period obviously during the veg period you will use more electricity because of the lights etc being on for 18 and off for 6... whilst in the flowering period they will only be using juice during the 12hours they are on .

if you think of 7 days or a week of 18 on and 6 off (veg period) will give you 126 hours (7 x 18) of pulling juice
whilst in the flowering period you could run the lights for 10.5 days for the same cost :)

I would definitely do 2 600's. It can't hurt... the elctric bill could go up a lot though, if the company has a baseline limit. The more lumens the better!

You have no chance if you dont use cooltubes mate trust me i run a 240x120x200 with two 600w cooltubes and have problems with heat a 6inch rhino filter and rvk fan out and 4inch intake. better trying two 400w
