question about autos

I use MH until about week 1-2 of flowering, then switch to HPS

Okay, thanks dude. That's what I was thinking.

if you only have access to one type of light for the whole grow then use a flowering one otherwise a veg light for the first 4-6 weeks is best

Well, just my reading around seems to point to HPS start to finish. And since we don't have to worry about creating a photo period, and massive growth can happen with 24 hr light, most folks just do that. And HPS is better than MH because it is cooler to run it.

I've used HSP or MH bulbs to grow autos. Important thing is to keep the lights at 20/4 or 24/0 for the duration of the grow. Remember - autos do not veg. They go straight from seedling to flowering. That's why you can run without changing the lights. Some swear that you need MH light to increase greenery during veg stage. I've done a ton of tests and there is not much difference in outcome with autos. HINT - I've had good results by putting 2 auto seedlings in the same pot and growing them that way. I seem to get more growth from both when they have a partner. BigSteve.

If you have only 1 light to grow with I would go with HPS. Im not sure how large your grow space is but there are all sorts of sizes of HPS lights from a 150watt with enclosed ballast all the way up to the big 1000watt lights. Just keep in mind the bigger the light the more heat build up you will have to deal with. If you are growing in a confined space like a tent or box then you should look into getting a vented hood for your lights. I tried to do things the cheap way first and ended up buying everything twice. Make a clear diagram of your room before set up to know what all you will need. Good Luck Dude

I am currently vegging 2 regular fems. But when I put them in the flower room, I am going to start an auto. Thats why I'm asking.
