2x55W PL vs 70W with 2x18W Actinic PL

[Jameshong]

Hi,

Think of modifying my RSM stock lighting of 2x55w PL to 1x70w MH with 2x18w actinic PL light if there is no much inprovement then I might drop off the idea.

Any comments or advice are most welcome

Go for 150w MH if you want to mode it, more option for the bulb range and brand.

It also depend what are you intend to keep, for sps go for MH.

The original canopy can't withstand the heat from 150w as adviced by DE. However, the nanocustom in US is able to do that with their kit set but is very Ex to import and also the concern of different AC voltage.

My sps grow quite a lot under stock lighting but colour loss out abit so thinkin of fixing MH.

might need alot of cooling (Fan) to reduce the heat in order to suceed using the 150watts. the last time i mod, it was using the existing fans which i think its not sufficient.

Can incorporate heat sensor incase of over heated ?
