I am planning a heavily planted tank... I have T5 HO light at 6700K twin tube light 39 watts each... Its a 38 gallon tank... I want to set up a CO2 injection system. I already have the tank and the regulator. The regulator does not have a needle valve so I'll get one of those. What else do I need besides a bubble counter and a diffuser? Also any tips would be appreciated... Thanks..

A drop counter about a tenner from Ebay.
Its a personal choice but a solenoid valve will allow you to plug it into a timer for on/off capability. At night plants don't really use Co2 since they really only photosynthesize when the lights are on so the excess co2 at night can be a bit too much for the tank and isn't really necessary. Plus it'll make the co2 tank last longer.
Drop checkers stick to the inside of the tank and measure the amount of co2 injected. Inside the drop checker it is filed with a 4dkh solution and a few drops of bromo blue. The ultimate goal is to set it up so the drop checker is always green. Blue means there is too little co2 and cancause algae, and yellow means too much co2 and you could kill your fish.

Here you go. One drop checker. The blue colour measn i dont have enough CO2 in the tank yet.
On initial installation of the drop checker it can take up to 2 hours before you get an accurate reading. If you see now change after 2-3 hours go ahead and adjust it a little. Needle valves are pretty sensitive so be gentle or you'll blast a ton of co2 into your tank like I did on accident lol.
