I'll try that some day. I'm not sure why the light turns purple. I run two 15 watt lights to extend day light and evening hours for 80 seedlings, I'll do this for a month.Last year I used a different light during veg and my plant stretched. So hopefully I wont have a problem this year.
The weather here in Canada can be harsh so I bring in baby plants in for the night tell they can handle the weather, plus my plant will be big enough when its timefor the outdoors(Early May). Thanx for the advice
