I know I won't be able to go 600w, but could get away with 400w ONLY IF I am on 12/12 as that will be the same as running my 200w for 24 hours, but as I mainly grow autos a 400w will be rarely used.kbag wrote: ↑Sat May 12, 2018 7:41 pmWell i think the best option's would be either to upgrade your led or buy a digital dimmable ballast. You can buy a omega digital ballast ,shade, and bulb for £80. This then gives you option of running either a 250w bulb 400w or even 600w .The omega has 5 year guarantee and i have never heard of issues of interference with modern day digital ballast's.
As for led lighting i know my prakasa 300w would out perform a 250w hps hands down, i would but it on a par with a 400w yield wise with better quality bud imo. Oh and a lot cooler to run making it cheaper as the fans do not need to work so hard as often to cool.
Food thought Aspie but summer is virtually here.
I have a Spider COB, but that's a little more louder than the Mars II 400w and didn't find any extra in yield.
I do like LEDs, but the fans annoy me. I can hear the noise of the LED fans more than I can hear the extractor fan.
I just don't want to fork out on something that I won't be able to use. Money is tight as it is, so I have to get it right first time.
CFLs are silent, and music to the ears. I would have thought that HPS are also silent as there are no fans built in them.
I don't use a timer as such. I have it plugged in, but turn it on and off manually as it's quieter than flicking the switch.
I don't use air pumps either - soil grow.
I think I'll stick with what I have for now.
Thanks for all your help guys, much appreciated.
