Dimable ballast and full spectrum?

[JonnyJonny]

Does running your HPS globes at 50 or %75 hit the full spectrum capacity of the globes? Consequently are you reducing potential yeild by doing this?

For sure if they're in flower ,,,running the light at lower strength is better for different stages of veg .

 

Full power for flower , or turn it down if it's a stinking hot day.

This is what i thought and hsve been doing the same in veg, its really great for that-run at 50% for first week and 75 for second week. But problem is when i put up to 100% (for flower) seem to get few male flowers, mostly infertile though. Is 2x400w too intense for 1x1x2 metres?? Cheers jb

Not sure I get what your saying. Do you think the lights are giving you male plants? Not giving you enough males?

I've got a 400w dimmable ballast. Just bought a 250w hps for it. There's different opinions but for small coin go out and buy a globe suitable for for setting you've got your ballast set too.

If the ballast has the dimming by percentages then use the one globe .eg a 600w ballast use the 600 globe for 50 or 75 percent setting .

 

If the ballast setting are 250 ,40O and 600w .Then use the appropriate globe

Maybe you have the light too close causing them to stress and hermi

[JonnyJonny]

That was my guess, they are getting stressed and herming a bit. But it hasnt caused any major probs i guess because at the most im only finding a couple of viable seeds. Side note are they suppsed to be fem seeds when that hsppens?

 

Oodog they are girls only-was a bit confusing i know.

Midlife that is not a bad idea maybe i could get a couple of 250w globes or one and then i can peak them out.

 

Cheers serated, they are dimmable by % i will put them up to 100% shortly, just switched to 12/12 cant wait to see how this jack herer goes!! Hipefully no bananas this time

Also my tent is 1.8m high mot 2 meter. Bad memory so yeh maybe too close serrated when in last weeks of flower?

How far do you have the globe from the plants ?
