Sorry if I am telling you guys how to suck eggs, the agro bulb is for flower only, you can use the other one all the way through the cycle but the red spectrum bulb (agro) is meant to be used in bloom

And this sir, is why we do tests!
We will get to see a complete grow comparison of 3100k vs. 4200k. The results will be interesting and educating to say the least!! 3100k spectrum is not that far off the 3500 spectrum. It has more than enough blue to veg a plant, so it cant be for flower only. Its preferred for flower, but definitely not for flower only. But, the test results will have the final say, hahaa!

Hi man,

Have used only the elite and not the agro on a couple of grows and you still get lovely bud but people have advised you get better buds in yield and quality using the agro for bloom.

The pictures above are my first try with the agro for bloom and the plants flowers look really developed for the amount of time the agro has been in situ.

What would be the best hood for a 315 Nd does that effect yield?

Hi, maxibright ballast and supernova reflector, I need the adaptor in the reflector to fit the 315 bulb.
