Full service ballast and full service bulbs. Change bulbs out 3-4 month. Cost a wopping 2 bucks each. Now the full service mag ballast $38 bucks. but only last 20-40 years so plan ahead:dance:
Cool white shop bulbs for grow and warm white for bloom.
O god I see the light , but no snow job.
cpl and ecolight are a snow job for the rich.
Bulb surface area that hits the plants , is what counts.
This couple of shots kinda prove it. imp: imp: :thumbsup:
