Is this light ok to start with?

[magic bud]

i have purchased 2 lights to start off growing with they are ,36w philips master PL-L 840/4P 2900 lm, will these be ok ?. i have a 600w hps for later but im unshure about the philips any help would be much apreciated thanks

Why dont you just use the 600W HPS the entire time?

[magic bud]

iv heard it is much better to start them with something not quite as powerful, and it would be a waste of electric if the two 36w bulbs would work

[mellow mood]

2 36w? i dont think 72 watts would be ok for vegging. i guess you should use hps the whole time. it is "better" to use mh for vegging but who cares man

[mellow mood]

and how many plants do u have anyway??

[magic bud]

i am gona grow about 10 and half should be females

[JohnnyPotGrower]

If you are gonna grow 10 plants then I dont care what kind of lights they are, 72W is nowhere close to enough. Not only is it not strong enough, but it wont be able to cover the area that 10 plants take up... you are gonna end up doing more damage to your plants than good. Just go with the HPS, the electrictical bill wont be THAT much higher... you won't get squat if you use 76w.

i dont have an hps light ( witch i wish i could spring for one ) but what i do is use high powered compact floros to vegg with...then put them under the mh for flowering

[PartypokerPlayer]

u have hps so thats the best light for flowering...or so its been said...

Dude it's a proven fact not just an novel thought. Mh will take longer to flower and will not produce the same amount of THC as HPS will....FACT.

If you grow 100% with HPS I suggest you use a multi-spectrum bulb (enhanced bulb) and you would do just fine. There are other environment conditions you can control to increase yield and quality.

and you can buy conversion bulbs for any hid...

the 600wt will be fine get rid of the others..

thanks all for your help iv started now and im using my 2 x36w bulbs to start and all seems fine 2 mor weeks and im putting them under the 600w hps thanks again :D

Yea he kinda didn't say just use the 2 bulbs instead.

Using ur 600w is like using about 8 normal bulbs so just turn off a few other lights and stop complaining. It'll pay for itself in the end after all.

[magic bud]

Yea i know and im very greatful for the advice but i bought them so i wanted to give them a try they worked quite well but iv put them under the 600w now anyway and i must admit that it works much better leaves are growing well fast now thanks again all its much apreciated :-)

Magic Bud: i started with 2 flor's, 14 plants inches away from the grow and they turned out fine.. Flors are 2 20w argo for plants. let them get at least 3 sets of branches then swith to your HPS.
