Both the 250 W and 400 W models of the Philips HPI-T Plus bulb achieve, thanks to their cold white color, that the plants take out more nodes on each branch than with other growth bulbs.
If what you are looking for is the highest quality, do not doubt that with this bulb you will find it.
Remember that it is worth both to make the growth of plants that come from seeds and have germinated, as well as rooted cuttings or for the maintenance of mother plants.
Features of the Philips HPI-T bulb:
| Lumens | Useful life | |
| 250 W | 20.500 | 18.000 h. |
| 400 W | 32.000 | 18.000 h. |
Remember that to switch to the flowering phase, you have to buy another specific bulb for flowering and change the number of hours a day that it remains on.
Growlet tip:
Write down the date of installation of the bulb in the lighting kit to remember to replace it after 9 months of use (3 harvests).
