co2 isn't that important, if you don't have an actual co2 system I wouldn't worry too much unless your grow area is completely sealed.

does everything sound ok with what im gonna be doing will the plaster board keep smell in if i attach a carbon filter also whats best to grow blueberry or sky walker ? chers

what is your growing medium? You need to decide on a soil mix and a nutrient schedule. You could also use a fluorescent shop light to germinate the seedlings as 600w is a bit much for the first 3 weeks of the plants life. the boards will probably keep the smell out but you're still going to have to exhaust somewhere or during flower your humidity is gonna go sky high. Plants transpire moisture and if there's nowhere for the stale air to go, your humidity will get to 100% and you'll get budrot. So you definitely need an exhaust fan. A circulating fan is necessary too but that's a cheap fix.

All in all sounds pretty good. any other questions?

yes i have from tesco the floresent light energy bulbs 100 w i think they only use 25 w . If i say put 6 of these bulbs on a bord with fittings will this be good Enough just to grow them when they have seeded ? 1 bulb each plant in a small place ,, whats best to grow is it the blueberry or sky walker as i got 50 blueberry seeds and 25 skywalker im just wanting to do say 10 plants ? thank you for the help star ..
