Is it possible to control the amount of water that fills into each tray?
Yes, each tray has a seperate flow control valve.
Does it also come with the shelf too? Or no?
Yes it is fully assembled as seen in the pictures. The automated grow rack will come to you as show in the 3rd picture.
is it possible to grow small vegetables in with this rig, like very small radishes or carrots, petite bok choi, etc?
Yes, you could definitely use the rack to grow petite vegetables. Be sure to consider the height of your desired plants and order the number of tiers that would allow for that space between the soil surface and the lights. If the pots you will be using are taller than the standard 2.5 inches you will need to consider that as well. Many people use the 3 or 4 tier rack to grow seedlings.
Can you use these racks to grow regular seedlings for transplant to the garden? I am wondering if I can use this set up instead of building a greenhouse.
Yes and using our cell trays would probably work best. Keep in mind that since soil is going to be used a bit more system maintenance is required in order to keep everything clean and functioning properly.
Can you tell me how much the automatic grow rack 5 tier is ?
Sure! The 5 tier is priced at $2,299 (pre-tax).
what is the electricity power this system need? like in kWh? How much electricity it need for a day?
When the pump is on the amerage per unit is as follows:
5 tier - 6.8 amps
4 tier - 5 amps
3 tier - 3.5 amps
The kWh will greatly depend on how often you run the pumps. These plug into a standard 120V outlet.
Is one 1000-1500 gph pump able to water all five trays at once?
The 5 shelf rack comes with a 2700 gph pump. The the lower trays fill up a tad faster but they all fill up within 5 minutes.
Hello. Can I order the system unassembled?
Not currently. In a few months we'll be making it available in parts.
Will these automated racks support growing in coco coir, or other solid-type growing media?
Yes they will support various types of growing media.
