i have 3 blue bubls in it and one red. What do you think? will it work?
the light should be 2 inches above at all times? is this correct?
Here is the link with great info...

Are you using the bulbs that are shown with the unit from the link or do you have other blue / red bulbs that you are referring to? Makes a big difference on what tube you have exactly.
If it is, I think you will be ok in Veg. If I was limited on a 4 bulb unit, I would exchange one of the blue waves out for a 6500 in Veg. IMO
In Flower I would replace the two blues for redsuns or coral wave bulbs and that should work ok also. You dont have to spend much to get these and you will see much better results in Flower.
Keeping the canopy as close as possible with T5 lights is key. Using techniques like LST, Topping, Scrog, ect.
2" would be optimal but if your plants dont like it, pull them back some or raise the light a little.
Although I have never heard of using blue light to influence sex, you can help influence sex within the first 3 weeks from seed through nutrition and environmental changes. Its not 100% but you can stack the odds in you favor.
In soil, by keeping the PH slightly alkaline helps. The female plant is naturally slightly alkaline and male plants are slightly acidic by nature.
By adding slightly more N to the seedlings diet and by keeping the temps on the lower side 65-70 may help also.
But be aware, you can stress out the plants and cause them to Herm if not closely watched.
