400w Metal Halide for first month of flowering?

I just found a mushroom growing out of the soil in one of my plants pots.. Is this a bad thing?

Naw, probably not. There's a couple threads in the plant problems section specifically about unwanted fungi in pots.

Flowering with a MH will promote denser buds, because of node spacing, it also helps control stretch. so you are right on track Earthly.

There are people who do entire grows under MH and have excellent results.

What would be better, an entire grow with HPS or MH?

HPS... Because it promote flowering and thats the main idea...

Are you asking the question, "If I were to purchase only one HID light should I get a MH or HPS?" or is it purely hypothetical?

If it's the former, get the HPS and veg under flouros.

If it's the latter, I'm torn between saying it's important to minimize stretch (pro-MH) and it's best to optimize flower (pro-HPS). Being more concerned with clone production, to me it's a no-brainer to go with pure MH, but a bud grower would have to weigh options differently.

What is better?...an entire grow with both MH and HPS at the same time is better.

Thanks alot, I was just curious because I didnt know since the MH was such high wattage and K, if it was necessary to get the seedling/clone as close

An HPS with a blue spectrum such as the Hortilux HPS with blue spectrum would be the best way to go IMO. Test has shown that just a small amount of blue/MH light in the bulb will help to stop stretching. Also, hands down the most lumun will give you the best outcome time and time again. Also, I would only use Hortilux bulbs on a 600 ballast, they seem to have a longer bulb life than other brands when it comes to the 600. A 600 MH and 600 HPS is over kill IMO for a 3x3 area and you will have allot of heat issues as well. Done right you should be able to produce a Lb with a fair strain and a handle on your feeding schedule.
I haven't read the second page of this thread so, some may have said the same thing already, or completely contradicted my info, but you can easily confirm or dis confirm my input.

i was thinking about starting flowering under the flouros for the 1st 4weeks then under the hps , want 2 try and get a crop off every 4 weeks with out buying another hps.

Smokenss, then find a shorter strain, one that comes down in 6 weeks.
Flowering under flouros is not optimal but if you're going to do it that way I would not suggest going past the 2-week mark under flouros.
