Orite mate. Same boat as u. I started off with led 150watt which was a flop. Anyway got a 400w hps + ballast. Plan on using them both at the same time from seed to harvest, freedom seedspurple xpress autoflower. Would i be best to use the led til atleast 3or4 sets of leavs an then add the hps?is it a gd setup? Closet grow. Flora ghe 3part nutes. Ordinsry soil with perlite.

Hi everyone, as all you who followed my last grow using only LEDs will know, it turned out to be a right effing disaster. Started out well enough in the veg stage but was woefully disappointing when it came to flowering. Now comparing my new grow with that last one and with seeing how the buds came out that last grow I have come to the conclusion that the LEDs didn't perform as well as they could have because I was growing during the winter and my grow box temps were way too low resulting in the plants metabolism slowing to the point were they were just not growing at all.
I have searched for threads were growers were using a combination of LEDs and HPS for flowering and there doesn't seem to be too many so I thought I might as well post mine up for like minded growers.

This time Im only growing 3 plants not 4 like I did previously, I am using my vipar 300w LEDs (actual draw of 180w) together with my 250w HPS for flowering and I can say that the plants are already looking better in just 20 days of flowering than my last grow using just LEDs did at eight weeks, I put this down mainly to the radiant heat emitted by the HPS and the extra lighting.

I think using a combination of LEDs and HPS lighting really rocks. Hopefully this will make up for the disappointing last grow. The plants are a BLZ Bud, one NL#5 x Haze and one sugar punch. Can anyone here tell me if 400w of mixed LED and HPS lighting will be the same as 400w of pure HPS lighting or it wont be as effective ?

Will be updating as they come along.

Sounds like a good one, will be putting it on my list to check out, I keep a list going from recommendations, but definitely down the road. Right now I'm over-strained if that's a term. Got on a buying spree for the last few months so will be growing those out, as well as doing some of my own crosses/seeds for the rest of this year.

So far on my grow list for this year, currently vegging, seeding, and/or breeding:
Jack The Ripper (just finished and a keeper so will keep this one going)
Platinum Bubba Kush (just finished, have a couple more outdoor but supports PM so no more indoor)
Blueberry
Acapulco Gold
Blue Dream
Critical Kush
PPP (Pure Power Plant)
LSD
Pineapple Chunk

+ Breeding projects
Jack The Ripper (want my own stash of seeds)
Jack The Ripper male + Platinum Bubba Kush female (hoping JTR passes on PM resistance to PBK)
Jack The Ripper female + Ace of Spades male (should be a good producer)
Jack The Ripper male + PPP female (good producer + fire, both trains are mid-20's THC)
Ace of Spades female + Ace of Spades male (apparently this strain is being discontinued)

That should keep me busy for the rest of the year - lol
