Greetings friendly people... I'm just curious if anyone knows the difference between the Philips Son-T-Agro and the Son-T-Plus? I know the Agro doesn't (from my research) come in a 600W, and was thinking the 600W Plus is basically the same version of the Agro but in a higher wattage. I think I am wrong though. The Philips Lighting website is next to useless when it comes to finding information about their spectrums etc. They'll be under something like 'Highway Lighting' if you're interested, not a seperate horticultural section. Any help appreciated.

Hi all: I have a 400mh, and a 400hps hort. Instead of using just one to veg. would it hurt anything if I put them together and have 800w on them from start to finish or will this be better for the end result of more buds. :reallyexcited:

OK, THEORETICALLY, under ideal and identical conditions, if u had like 6 identical plants say on there fifth leaves and ready to veg, and put them in seperate rooms under the following lights, no topping etc, how long and what yeild would you expect to get off each.... with me ppl ?? 1 .

Hi all, Well, after a couple of moderately successful soil grows under 130w spectrum fluoros I've decided to stop mucking about and change to hydro under HPS. My growspace is small (60cm x 70cm x 170cm) and presently has 2 x 120mm extraction fans with passive inlet. I'm wondering whether I should go for a 250 or a 400 watt lamp. Heat may well be a problem for me with the hottest months still in front of us. Yeild is not hugely important as I suspect that even the 250 would be an improvement over my fluoros. What would you more experienced growers suggest. I'd really prefer not to have to up my ventilation as it's already noisier than I'd like. thanks,
