Greetings from South Africa. I recently started experimenting with indoor growing. I am used to growing outdoors, here in South Africa we have great sun, but it is quite a long time to wait for the plants to mature growing outdoors. I would like to try 4 harvests per year. I have HPS, but learned that HPS is not efficient in the veg stage. Could I perhaps mix the light with natural sun, say my HPS (on timer) goes on at 1 in the morning and off at 7....then I'll take them out until 7. I don't want to mess things up, because I've spent quite a lot of money on the room and equipment. Can this work?
