How much gram per hps 600 - Growroom Lighting - International Cannagraphic Magazine Forums

scarafino · 12-31-2017, 12:20 AM

Hi, I am in HPS 600w and I can not get out more than 0.5 g/0.6 per watt in soil I would like to get out 0.75 see 0.8 gram per watt!

I work in 3 gallon pot with 9 plant per lamp and 1 month growth starting from seed (critical + 2.0 Dinafem Seed)

Do you have any solutions to get me closer to the watt gram?

You think that with lamps Gavita 750 It would be easier for me to miss the gram watt rather than with a 600w HPS

Maybe your lamp is old, maybe your ballast is magnetic...these two factors drop the light intensity, for a start.
As Drop said, SCROG is the way to go for yields. Train your plants to get as many tops as you can, then switch to flowering.
Gavita 750W would be a big improvement over the 600W hps but it's very likely that a 600W led would get you over 1g/W.

Cheers

IMO your pots are to big and you are not vegging long enough.

If it was me I would have 9 plants potted up in stages with 6 litre final pots. Make sure they are fully rooted before flipping the lights, which should take 6 weeks at the very least.
I would top them all to create a nice even canopy with plenty of bud sites and then you should yield at least 2 oz per plant which will give you around 1 gram per watt

I used to pull an lb all day with 600w

You are almost at 1 gram per watt. Which would be roughly 2 lbs under a 1000w.

At .5gm per .6watts, your formula not mine (kinda weird) you are getting .83 grams per watt.

600w x .83 = 498 grams which is 1.09 pounds.

Is this post a humblebrag?

You are getting over a pound under a 600w. WTF? Read up on stuff. You only needs some tweaks to get more but you are doing fine as is.

He is nowhere near a gram per watt and hes growing under a 600 not 1000 and he said he cant get more than 0.5 to 0.6 gram per watt which would be between 300 and 360 grams which is really poor under a 600!
so maybe rather than telling him to read up you should read his post properly.

It looks like he said he is getting .5 grams per .6w I know he isn't under a 1000w. I did the conversion for easy math.

If someone is getting .5 grams per .6watts they are getting .83 grams per watt. DO THE MATH!!!!!!!

If he meant he is getting .5g -.6g per watt he should have written it that way. Not .5g/.6g watt. .5g-.6g is .5g to .6g The / is per.

And he still should look at the freakin 1 million threads on how to improve his yield instead of wanting someone to spell it out for him.

I am under a 600w and my yield is low. What should I do? If you can't get the proper yield from a 600w even if you go up to a 750 watt you still will be low yield for that lamp. He needs to read other posts and learn to maximize his grow.

There's nothing wrong with my maths!!!

it's your READING that's the problem

and i have already given him advice on how to improve his yield, its quite obvious he is not fully rooting out his pots in 4 weeks of veg and his pots are to big,6 litre final pots are more than enough.

I do agree that changing the light is not the answer
