General Description     1, Injection molded ndfeb magnets can be of very simple shapes or very complex     2, All or only part of the device may be magnetized     3, It is sometimes cost advantageous to make an entire part out of the magnet material and just magnetize the portion requiring magnetic output     5, They are manufactured using both injection molding and compression bonding techniques which are fully automated and are particularly suitable for high volume production
Ultra Plantâ„¢ Grow Light offers One Chip Technology aimed to meet your indoor growing expectation such as improve plants' quality, increase yield, or better the margin, etc., all for helping you realize a higher return on your crops.
From Ultra Plantâ„¢ APP, you are able to schedule the growing process including photoperiod, brightness and spectral in advance. The lighting system will help you grow smarter, easier and better.
