I am currently using 175 watt 4200K metal halides bulbs at a cost of about
$25 Cdn each. I finally found 5200K bulbs but they are $77 Cdn each.
For people that have switched to a 5200K (or comparable daylight) bulb - have
you noticed a minor or major impact on plant growth (keeping all other plant
requirements the same)?
