Thanks a lot guys. On Friday I'm going to buy one more t5 and other one on the following Friday. This is what my box is its a cabinet from home depot with three rooms in it. The top one is 2 feet deep 2 foot tall and 4 feet wide and the other two rooms are. 2 by 4 by 2. I'm using pc fans to keep it cool and quiet. I'm trying to stay as stealthy as possible in march ill be leaving for a week what's some ideas to. Get it watered while I'm gone?
Ooooh. I don't know. But I have a timed watering thing for my regular garden (herbs, tomatoes, flowers, etc). It might output enough water to water your smaller plants (definitely not big ones). But even something that small costs over $100.
Automatic watering setups are not cheap at all. I don't know if anything else exists out there like that. And mine is outside, if you put one inside and go away without checking on it often, you run the risk of it malfunctioning and overflowing.
You can try transplanting into a bigger pot *just* before you leave and soak it in water. That way, the soil where the roots haven't grown yet will retain some water for later. Of course, this may not be possible with your space limitation.
I've also heard of people using 2-liter bottles filled with water and turned upside down in the soil to slowly release water. But again, I don't know how that will work with your space, and you may want to research that a bit because it just sounds like it wouldn't be too good for the plant. And I would imagine overflowing might be an issue.
You can also take the pot out of the drip tray and place it into something that can hold more water. Water the plant before you leave and fill the new, bigger drip tray with as much water as it can hold. But this may be limited by your space too.
Of course, I wouldn't really go with any of those options, personally, because your soil would be constantly moist. That in combination with warmth from the light and dark after the lights go out is just a breeding ground for mold. But they are options to consider if absolutely necessary.
