Hey Garret..

I helped you on this thread you started and answered some of your questions.

Take care

Mike

I dont think that t5 would be enough. I have a 4 foot 4 bulb above an orange and grapefruit tree that is sitting in front of a south facing window which works. My t5 setup is 216 watts so yours if going to be about half of that. To really get good results with a light as your only light source you really need a HID setup of atleast 400 watts.

I am considering replacing the T5 grow light with a 150w HPS. I feel like the T5 is better for my non fruiting tropical plants. I chose the 150w HPS because it is affordable, at just $66 and because it produces 16,000 lumens (compared to 8,000 from the T5). Also, it will produce more heat than the T5, so the grow tent will be much warmer.

Mike - I am always pondering better (or more effective) ways to grow my tree. I apologize if I am repetitive. None of my friends are interested in horticulture or container citrus growing, so I do not have anyone to bounce ideas off from.

Citrusfrak, have you had any success with your trees? Any pics? You said that a 400w HID would be right for growing as the only light source. That would bump the price up to about $150, which will be out of my price range for a while.

Has anyone estimated how many lumens a dwarf citrus tree should receive? Any thoughts on this light?

Garret, I have no problem with you being repetitive, and in fact that is not what I meant.

What I am saying is that you never followed through with your questions on the other one and I didn't think you noticed your questions were answered,

Have a nice night and good luck.

Mike
