First grow (revised)

[DurbanStone]

I start all my seeds in dirt and weed out the males and use the dirt plants as mothers. I get near 100% success that way, it's real easy. Just keep them warm and moist (not wet). That's almost impossible to do with RW. You can use a Vermiculite/Perlite mixture, Rapid Rooters, a sponge, and I think stinky attic recommends bark plugs. Never tried them.

My last Vortex came with cord attached. If I could save $25 by getting a CanFan and attaching the cord, I would do that since it is so easy.

For seeds, check out these two places:
Buy Marijuana Seeds and cannabis seeds from Holland - high quality marijuana seeds (cannabis seeds)
Marijuana Seeds (cannabis, pot) shipped worldwide

Both are good, the second one is more expensive, but they have a bigger selection, and even more important, I've never had a problem with them. I do want to try the first one next time, if there is one. Their site impressed me a little. I wouldn't waste money on fem seeds since gender is determined soley by genetics. Notice how it's kinda the same word? Fem seeds are a bunch of hype. You can expect 60 or 70% female from non feminized seeds. People get that when they order fem seeds and go, "see, fem seeds really do work" when its the same for non fem seeds. Power plant for the high yielder, Daddy's Girl, Blue Berry, Northern lights, Northern bright, Haze, G-13 x Haze, all make real nice smokes, and of course you cannot go wrong with the ever popular White Widow, or White Widow crossed with something else good. If you by crosses, they will cost less and you will get the best of two worlds.

The room will get pretty hot if you have a sog going and have both of the 600W lights going at the same time. Not so bad if you are doing the whole grow with one light at a time. That would be perfect for the 4" inline fan, but I don't know if there are 4" cool tubes, so you would need to get two 6 to 4" reducers, or build something yourself for reducing. If you are running both lights at the same time, I should think that a 6" inline would do the trick nicely. High output. Always high output on either the 4 or 6". A little more money and worth every penny.

Weird, I thought I remembered Zondor saying fem seeds actually do work...

I was actually only getting one light, a 1000watter... but someone told me to get 2 600's, but I think that's too much for a 4x4 hut, and an extra ballast and...

Thanks for the seed suggestions.

Glad I can help. If your not doing sog, you could have one 1000W. In that case make sure you get a digital ballast so that you can do both MH and HPS with a conversion bulb. I would probably want a 6" fan for the cool tube, and one or two more for circulation.

And about feminized seeds, and doing things to feminize: I have not seen any scientific proof that feminization methods work. It is a controversial and touchy subject. Many experienced growers have said that they have tried feminized seeds and other feminizing methods, and they don't see any difference. On the other hand, some people swear it works. I'm with the group that believes gender is determined by genetics, and you can't change that unless you have decoded the MJ plant genome and know how to manipulate the dna of the plant at a submicroscopic level. Let me know how that works out for you.

I'm getting the votex 4'' for the air cooled hood, and yours saying ill need more ventilation?

I'm not sure what I'm doing in terms of how many plants to be honest. So there are single bulbs that are both mh and hps? And on the ballast I just switch it?

[DurbanStone]

Oh I see, I need a HPS BULB, and a conversion MH bulb?

[Opie Yutts]

I said it backward, sorry. A digital ballast will be HPS, and you can run MH with it also, but you'll need a MH conversion bulb.

If you go with 1000w, I would think a 6" fan and duct run would do best, but you may be able to get by with a 4" high output. I'm thinking 4" would be fine for a 600W. You also will need a small oscillating fan to make the plants gently rustle in the wind. This makes them strong so they can hold the weight of all those heavy buds to be. You also need some way to exchange air in the grow space, unless you are doing that at the same time with the enclosed hood. Some people run the warm air of the grow space through their cool tube or enclosed hood. I tried to make this work, but had horrible results.

Also you will have much better air flow if you use actuall ducting material and not the coiled dryer duct. Changing over totally solved the heat issue in my veg section.

And you can't do that if you plan on using CO2.
