I got 5 (2) bulb t12 fixtures. I got 144 clones under 4 bulbs putting out 3250 lumens each. Gonna be starting a few hundo bag seed seedlings under the rest of the bulb and force sex them before they go outside. Anyways, my question is the t12s are in the 4100k color spectrum or some shit...maybe 4200 i dont member. I got them cuz they have the highest lumen output, however whats more important....the lumen output or the color. The correct color spectrum i want is blue (2100K i tihkn or maybe its 6500k, i cant rmember but a quick google will refresh it)... Is lumen output or color spectrum more important. I will only be doing veg growth with these (except for force sexing) Thanks GC Oh ps a few of my cloens got mold in them cuz i forgot to take off the dome off the fucking peat pellet tray. God damn me...im gona spray them with a little H202 (Hydrogen peroxide)...its 3% solution...should i dilute it more? Also i took my clones VERY far into flowering becuase i did it last year except early and that monster cropping business is so true, i suggest anyone who starts indo and moves outdoor to take their clones form a flowering plant. fucking bushes
Hi The most important thing is colour-spectrum. The lumens output is only the light-intensity. The colour-spectrum is what wavelength and temperature the light is. And by temperature i dont mean Celsius or Farenheit, but Kelvin, the colour-temperature... So if you got the wrong colour-temp the plants will not be able to use the light it gets. If it's the right colour-temp, but too low of a lumens output, you can just get more of them, and get the same results as you would with more watts. Example: 1 x 400 watt HPS: 55 000 Lumens 18 x 23 watt CFL: 54 000 Lumens (one 23w CFL = approx. 3000 Lumens) The difference is that the HPS sends out much light in the wrong spectrum, e.i. green light, wich the plant reflects. In the CFLs the light is often much more PAR (photosynthetically Active Radiation, the light wich the plant uses), and you can find CFLs with 100% PAR. So you can get bulbs with only red and blue spectrum with 100% PAR, and it would be much more cost-efficient. I belive your bubls with 4100K or 4200K is green light, and not much beneficial to your plant, if any. I would discard the 4100K and replace it with 6400K or 2700K. For flowering you need more 2700K and for veg 6400K. Personally I would have like 6 x 6400K and 2 x 2700K for veg and the other way around for flowering or something like that... Moe
