Flowering with MH

(Much better to save money and buy a conversion bulb than it is to buy an entirely new lighting system, right?)

Can't say I would agree with you there. For about 2 thirds of the cost of that 250W conversion bulb I bought a 600 W HPS bulb, reflector & ballast as a system from ebay including delivery. My own PowerPlant 250W HPS system is rated for MH as well without requiring any switch & the source I use for bulbs is £11.99 for 250W. Due to the size of the standard horizontal relflector, depth of throat between the fitting & the metal etc it would not fit the diameter of that conversion bulb. Without much work I could find a few partial or complete grow systems based on HPS for which there is much evidence to suggest the ballast can accept a standard MH bulb without the need for a conversion version as well as those stated as being switchable & have change from the cost of the conversion bulb.

Sometimes it s cheaper to throw out awkward equipment & renew a system to something more scaleable & conforming to popular standards.

Each to their own though & good growing to all.

Thanks to all for the answer really apreciate. here

It is right, i am now using a 250 Watts MH system, and just curious about flowering with a MH spectrum, because i cant get HPS right now, so i will be keeping vegging till i get the HPS i get in conclusion for ur answers, i been reading a lot and wondering answer from ppl with experience, not just thechnical information about spectrums, sometimes help more, you know i just got 1 plant so i dont want to mess up the things, and here where i live it is really dificult to get some seeds

It does make sense to invest in quality equipment, I can't argue with you there. I just know how frustrating it can be to want to find a better system, but have limited funds to do so. I had to use a conversion bulb for my old HPS, because for the longest time I simply couldn't afford to get a new switchable system.

I don't currently have my dream setup - partially because it would include a small warehouse :D - but I do have a new digital/switchable 1000w system in place...and I'm very happy with the difference. Plus, now I have two different HPS ballasts/lights that can be used, both of which have fairly new conversion bulbs. I'm sure I'll be able to find a good use for them!

Ojitos - Best of luck with your grow. :thumbsup:

Yep still working on building the system myself I was just lucky with my first set-up that it has the plate on the side identifying it as running both without switching. I would have looked at a MH conversion then the same as yourself as they are cost effective.

Ojitos Seen your plant in your other thread if you reckon you will some funds soon to get a flowering lamp then I would say keep gowing in veg for now. You have something that could be a really nice plant Mr Clandestine & myself may have been chatting about how to go about it but were both saying the same thing in that MH will not provide you with a flowering result deserving of your work so far & whatever way you can get a proper flowering bulb when you can.

Other than that good luck keep growing.

Bud density won't be ideal. Invest in a HPS when you have a chance/cash. Save the MH for vegging. A good ratio for veg watts to flower watts is 1:3 so if you veg under a MH 400, you can efficiently finish under 1200w of HPS. This means, when you get a HPS, get one much larger than the MH you already have (as long as you have the space to run it). You'll see... it's a question of continuous canopy.

Having sampled alot of pure MH, the bud is not nearly as dense. What looks like a decent ounce crumbles into dust if you let it get too dry, I want my bud so dense I cannot crush them with my fingers. MH will definately give you good stuff, though, the main stuff I smoke is purely MH, and it's aight. Get yer rollin papers if you using mh exclusively. Just one dumbasses opinion though, I'm usually too stoned to think much anyway.
