REversing the cycle helps us a lot tooo... if we kept our 4 600w on during the day at the moment it would be 40celcius with all the fans on and extactors because its soo warm outside.. reversing means nice dark period and similar temperature day cycle.. stable is the word
SpiritLevel Reviewed by SpiritLevel on . Ballast question Hi all I got a 400W MH lamp with a ballast. Also have a 600W HPS for flowering, also with a ballast. Problem is, I'm vegging with the 400W but the weather is just too hot. I can manage temps with difficulty. If the weather doesnt change soon, I will have major problems with flowering once I switch to 600HPS. What I want to do is to get a 400W HPS bulb for flowering, I'll use the 600W exclusively in winter. Question is, can a 400W HPS bulb be safely connected to the ballast of a 400W Rating: 5
