Wait which ones are glass? The clw? That was a bit confusing. 90 degree penetrates more than 120 right? And 60 even more right? Im not doin sog flood table anymore. Gon back to big plants. So I would want more intensity. Im just covering all my bases. I do not want to regret my purchase. I hate it when that happens .....

Yes, the smaller the lens angle the deeper it penetrates. HOWEVER, keep in mind if you have a dense canopy, deeper penetration will have little effect. Side lighting is the solution

Here's some 411 on 630 & 660 from one who seems to know "Couple that with strong white light (green-response chlorophyll extending throughout and deep into leaf structures, with a net effect at or near that of the (mostly) surface-level blue and reds), which also takes care of most of the ~660nm+ you actually need for photomorphogenesis - and you can get by with 630nm reds just fine.

(i.e. 630nm red is ~95% of the PSR of 660nm, AND they currently still have ~20-30% greater radiometric efficiency - as well as being cheaper than the deep reds - so there's more 'bang for the buck')"

Ok cool thanks.

The veg master seems to have the best spectrum for flower. The bloom master doesnt have enough blue for chlorophyll a, b, and, c.. Plus the blue photons increase oil resin production.

If more blue is what you like for flowering spectrum, then I would say the spectrum for you would be the full cycle, more blue than the bloom master but more red than the veg master, which you would need to supplement with extra red for desirable flowering results. What might be an interesting test would be to run a veg master and bloom master together and see how that works

Also remember 75% of light that chlorophyll absorbs is between 660nm. andd 700nm

The redsun and deep red are the same price.

According to their spd's all the lights have the same amount of red. Maybe there are more red diodes in that perticular light. I didnt check that. But if those spd's are correct. They are producing the same amount of energy at the 660 peak in each light.


I do like your idea. Its like hps/mh but better

exactly, i believe the full spectrum just has more red diodes.
 
i decided on the apollo 8. Im gettung 2 of them. true 270 watts each. they are $238 each . So $476 + $165 shipping. the rep i talked to Mr. Liu. said mid to end of august they will have a switch for veg to flower or both. i might wait til then. I don't know if that will up the price. I probably don't even need it. I'm only going to be flowering with these. later after that Im a get an apollo 6 ($189) for my moms.
