Hi guys I know someone can help, I am in new territory here, I have bought a coolray air cooled reflecter with a 600w Son T tube, cooled by a canna fan.fed with, I think its a growlush electronic ballast with 60,80 and 110% taps, in the very basic instruction book it said it will also drive HID. My question is; Does the HID bulb have to be 600w or can it be 400w? Also I know it might seem dumb but do I need 600w for vedging? I just want to buy the right bulb. I have given the led the arse after useing HPS on the last grow and now want to kill this next grow, not literaly of course. I have a 1.2x1.2x2.0 mtr tent and 2 extractor fans and filters. Thanks Tangwena

I found this comparison interesting, it could have been more accurate in that they could have used multiple bulbs from each manufacturer and compared how the bulbs perform in different ballasts. However that would have blown up the cost of the comparison astronomically so i can sorta see why they wouldn't. Summed up, out of 9 bulbs the hortilux 1000w won, followed by Ushio and Digilux - badass, solis tek, lumatek and maxlume were mysteriously close, perhaps even coming out of the same factory ? The difference between the hortilux and the 4th position was quite a large margin of 18%, that is a pretty big difference! Detailed results can be found here: http://growe…

Gents.... I'm looking for some advice on throwing a filter on the intake to prevent sucking pests into the grow tent from outside (pulling in from outside as it will be cooler).

Hi guys, I got a greenhouse that is 3.1m x 1.85m x 2.5m Id say it has roughly 14 cubic meters of air, the idea is to vent the air in this greenhouse though insulated ducting out of the roof of this greenhouse, then into the roof of my house. The air will also be filtered. The location of the greenhouse is wedged in between my house with approximately 1m of awnings and a about a 2.4m fence, the top of this fence has white laser lite which will reflect some light and also let a little though. The sun passes over the house then over the fence, so the location does not get full sun all the day, but will get a few hours every day and a bit of shade - so the greenhouse wi…

In todays age of digital technology,we have a wide range of gizmo's that leaves us spoilt for choice.From fans,timers,ballasts,to the complete enviroment controllers,depending on how much coin you want to spend. Making our grow area's easier to maintain a healthy and consistant enviroment, the biggest and most recent change being in the step towards digital ballats,First just digital,then mh/hps compatable with a dimmer feature. Now Matrix (Solis-Tek) have the 600/1000w digiballas,now most digital ballasts on the market are "regular digital" solis-tek are "true or full digital" ballast,and are bringing out the new model shortly. Big deal you say ,and i did too. What …
