Apollo Horticulture GLK400GW19 400 Watt HPS - Anybody have?


New Member
I'm thinking about getting this off amazon to improve the flowering stage of my plant. It is big and healthy with lots of buds all over but they are small and airy, not filling out. I don't think it is getting enough light. I'm using a 300w LED (I think it is only 130w actual output) and 6 100w CFL (actual 23w output).

If you have good experiences with the apollo model 400w HPS for flowering please let me know so I can buy it asap.

I use Apollo - 400W digital ballast/400W MH/HPS cool tube to include their bulbs. I have had great success with Apollo flawless operation thus far. Hope this helps.
