I'm not experienced in most areas of interest, so I won't comment.

However, I was faced with the same problem you mentioned in (4). Two months ago I was going home for winter break (30 days) so I bought an Oasis watering system. It cost me $90, but it made my grow possible. Something like this might help you out.
(I have no further use for the system, so I'm selling it now... http://boards.cannabis.com/showthread.php?t=52030 )

You also might be able to find something like this at a local gardening or hydroponics store. Good luck with everything.

smoknjoe Reviewed by smoknjoe on . Just a few questions from a new grower... I am currently doing a closet grow with two plants, about 3 weeks in. Regretably, I dont have the skrilla for a camera, but the plants are fine. I just have a couple general questions regarding my setup, nutes, etc.... (1) I got bloodmeal to mix into my soil when I transplant right before flowering, but how can I use it before hand as a fertilizer? Tea? If so how? And I bought Miracle Grow Bloom Booster (10-52-10). How should I use this, and should I even use this? (2) As to lights, Rating: 5
