12 posts in this topic

I have PHILLIPS SON-T PIA bulb. It came with 400w hps cooltube set.

Hi mate,

tokage is right; it is an improved son-T

I was using son-t bulbs almost 20 years ago.

Besure to replace your bulb after 9 to 12 months use at 12/12.

I replaced mine every 2 crops.

I now prefer the Sunpulse bulbs.

also if you can give you plants when they are flowering extra blue light.

a CFL is ideal for adding extra blue light. Choose one with a spectrim around 6k.

take care

john

Hi john,

whats the point of giving blue light at flowering stage?

Do they grow more compact or what?

I suppose that plants need blue light only vege stage.

ok mate,

no worrys.

In my experience to increase your yeild, by the buds being denser and heavier, you need more blue light.

in flower, i suggest, you use your halide as your main light, but suppliment it with red light from a CFL.

The plants need more blue light than red through out their life cycle,

but in flowering they need more red than they did in veg on 18 hours.

They need still need blue light to continue making energy through photosynthesis,

this is the case especially during flowering.

A HPS used on its own lengthens inter node length;

the buds, therefore, are not as dense or compact

as when a halideis used supplimented by red light either from a HPS light or a red CFL.

I know this from experience;

there isn't much difference in using HPS full cycle and MH full cycle, with the MH pumping out less lumens and WAY more blue light.. getting a nearly identical crop if not better, that should say something to someone... can't really find hps vs mh side by side can you? :P its negligible

yes i agree flail, difference between 2 methods are not big enough to say one is better than another ^^

I think it has to be used in case you know you'll have a more stretchy plant for example maybe. now what i do is start flowering with mh until stretch ends and buds forms nicely and then i put hps back when flowers starts to get bigger.

Using a MH during Veg and during the transition stage decreases stretching for sure..... And adding it back in the last 2 or 3 week of flower seems to increase crystal production. Not convienent or cost effective for bigger crops obviously.

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
