any advice how to get the biggest plants with the strongest buds, and biggest yeilds? im just learning, so anything helps! thanks!
Nice plant!!!150 watts on a flowering plant won't yield much, especially if its fluorescent light.
but yes, that plant has pythium and is never going to amount to much.
People should understand that if you are doing things correctly with good genetics, you should be able to turn this
and 10 days later have this:
How many side by side comparison grows have you done?Yeah I only veg with mh it's a lot better for veg man try it tighter nodes faster veg growth hps 100% for flower
600 watts of T5 lamps put out more heat than 600 watts of HPS.Also, is your environment able to handle a HPS light? Those suckers will pump out some heat if you dont have a way to vent it out. That heat in a small room or closet can be a death sentence for your plants if you dont handle it well. CFL and T5 lamps also put out heat, but nowhere near as much as a 600-1000W HPS lamp..
My last grow nlLink did not work
You need a ballast, a base, the correct wiring for the base and ballast you are using, a reflector or hood/cooltube and of course the same wattage bulb as the ballast is rated for and that will fit in the base you got. Most digital ballasts will handle both MH and HPS bulbs.

I dont have a lot of experience to pull from, being a new grower. I'll preface what im about to post by saying that.600 watts of T5 lamps put out more heat than 600 watts of HPS.
600 watts of MH puts out more heat than 600 watts of HPS
600 watts of LED lights puts out more heat than a 600 watt HPS
Im not sure what you're trying to point out. The sun will put out more heat, regardless of the temperature on earth. It has a really big room to shine in.What puts out more heat? a 400 watt HPS in a small room, or the sun on a sunny day that is 10f outside?
In the first sentence you admit you have no experience, then later you rely on that non existent experience to help bolster your argument that HPS puts off more heat than t5 and LED.I dont have a lot of experience to pull from, being a new grower. I'll preface what im about to post by saying that.
I would have to disagree with your previous post, at least mostly. Im sure that equal wattage most light types would produce similar heat, barring LED. That being said, the way the heat is dispersed will greatly affect the grow room.
For example, I have an 8 bulb T5 sunblaze light that pulls a bit over 400 watts. The panel is roughly 4ft long by 2ft wide, and has the eight bulbs equipped with spacing between to allow for dispersion. Your typical 400W HPS (http://www.htgsupply.com/Product-HTGSupply-400-watt-High-Pressure-Sodium-Grow-Light) has all that light contained in one bulb in a 9" long x 4" wide x 5.5" tall housing.
If a new grower decided to use a light light that in a small room, and didnt allot for temperature control and venting, I would assume the light would do more harm than good. It may even cause a fire, if the person wasnt aware of the possible heat buildup.
I still stand by my post. OP, do whatever you think is best. Just know that the stronger the light, the more heat you are going to have to deal with.
Also, in my personal experience, a good lower watt LED panel with heatsinks/fans produces practically no heat no matter how long you use it. Im sure that would change as you increase the wattage, but im willing to bet that the temperature range would be significantly different if you side by side compared equal wattage fixtures.
So what you are saying is that a 400 watt HPS will heat the room more than a 400 watt LED?Heat in a small space can cause trouble if you're not ready for it. If you can handle it, go for it. You will probably get better results. Peace.
But hps makes plants stretch mh keeps those nodes tight .. IMO because of that u will get bigger longer tighter nuggs using both hps and mh ....instead of unconnected nuggs or smaller nuggs everywhere using just hps...Not true on a watt for watt basis. HPS is way more efficient, in some cases up to 50% more lumens from HPS than MH. MH may have a bit better spectrum for veg, but HPS blows it away in actual useable light given off. HPS will give you bigger yields comparing same wattages.

It is also of interest to note that MH bulbs typically last only half as long as HPS bulbs.
Lol are you saying an led puts out more heat then hps..lol u should stop comparing hps to Chinese LEDs..So what you are saying is that a 400 watt HPS will heat the room more than a 400 watt LED?
Already proven as false, why do you continue to perpetuate false information? Do you want the person to fail?
Concentration of heat is nothing, a 10 watt LASER puts out much more concentrated heat than a 1000 watt HPS, but that doesn't mean its going to heat a room up more. Efficiency is what its all about.
HPS doesn't cause plants to stretch, old wives tale. Internodal spacing might be a bit tighter with the MH bulb, but the overall yield would be less. If less is more in your book, then have at it.But hps makes plants stretch mh keeps those nodes tight .. IMO because of that u will get bigger longer tighter nuggs using both hps and mh ....instead of unconnected nuggs or smaller nuggs everywhere using just hps...
Watt for watt HPS puts out less heat than LED, CFL, MH. Fact, incontrovertible fact, scientific fact backed up by tons of evidence and measurements.Lol are you saying an led puts out more heat then hps..lol u should stop comparing hps to Chinese LEDs..
