What you experts think of dual spectrum lamps? Or should i puts HPS lamp i have both of them ? changed the timer for 12/12 so flowering will officially start tonight!
Well I'm no expert, but i have made some personal observations. i had a buddy growing in very, very similiar conditions to me, in fact I;d say his girls looked more robust when we both went into flowering. I had a 1k hps (hortilux super "eye") and he had a hortilux 600 super eye, and a 400MH. So we both had 1k of HID on very similiar shows otherwise. Anyway the bud density and final weights werent even close. Now this wasnt a scientific experiment by any means, BUT the 1k HPS just blew them away. Such denser buds, so much more weight.
Now the 1k probably penetrated better of course, but still both grows were at 1k watts HID. A good HPS ( bulbs really, really matter) is just the shit right now in the flowering world. i don;t think anyone has come up with something even close at the same wattage to be honest. i think we all wish they would, ciuz the 1k bulbs are hot little bitches, and need to be cared for as such, but they are still your best budmakers....period.
just my 2 cents. Incidentally i dont even use my MH bulbs anymore. i use all flouros in veg, and hps for flower. i still have 2 400MH set-ups, i just dont see the point anymore. Flouros vegg more effiicently when you have your time tables down right. They are slower than MH, but i think with a watchful eye, i get better plants with the flouros.
Long post, but i hope it helps a little.
