Yeah for sure, you have a great weekend as well. I'm sure blowing yourself up will be fun lol.

Lol and about my girl and I, I will keep that in mind .... Mind lol.

Have a good one .

so I went to the store and whatdya know, after waiting in the trunk all night to get there the light decided to work again, THANK GOODNESS!

today was a warmer day, all weekend will be and I am going to try to practice heat control during this time, any suggestions? I got a bigger fand and put like a galon of cold water in the corner...Temps at 79-81.5 humidity down to 40% should I worry? During the summer humidity and temp going to be a problem since I dont got AC


Here are some pics, seedlings are bigger and all of them sprouted and are looking good....I used those CFL's while the light was having a personal crisis

Do they look healthy?

I was thinking of putting a lot in 1 gallon pots this week, is that too soon?

is that last pic show a stretched seedling?

the entire closet is now empty except for the growing equipment and watering can, more air and easier to cool it down was my thinking there.

thanks for all the help so farkiss-ass

Hey Jack, good to hear your light's working again lol.

Your plants are looking fine, you might want to drop that light though. 4-6 inches above the canopy for a 250 MH, that'll help with any further stretching.

Cool Mist Humidifier, if you live in a dry hot place like myself. That'll help bring up humidity and cool down at the same time. Just make sure to put a fan behind it so it pushes the cool breeze around.

The less crap in your grow room the better, you were right on about that. This will help prevent unwanted pests, mold and make the heat much easier to control.

Keep it up you're doing fine .

Hi Guys, good to see such a dedicated and helpful thread, Theres none other on the WWW like it.

Ok, first off i have taken quite a lot of time to go threw this thread nest i can so im sure you can appreciate theres alot of posts. I have a few questions which will help me greatly for my new venture.

Closet/Cupboard stealth grow.

60cm wide, 80cm long, and 175cm tall, its a wooden plain lightproof cupboard/closet.

My plan would be unless otherwise advised different is for just 1 large floor and drain/ebb n flow type pot, (very Large) 1 eminized Fat Indica, from Seed to Harvest in the same pot. Topping on the 4th node, allowing 5-6 weeks in veg.. I would also try a similar LST, but with thicker chicken wire. In a V shape meeting at the bottom, encouraging my main growth spouts,all potential cola's to grow up and along this wire, thus all reciving equal light.

Now. 250W HPS is that my choice, even if i decide 2 short indica,s my dimensions is a 250hps suitable for the job... I have heard there not fantastic in Veg, is this so much of an issue that it may be worth me investing in a couple of T5's i hear so much about. Or is the growth in Veg, not to much to worry about with the performance i will get in 12/12.

Also , due to my space, heat may be an issue. How do Aircool 250hps compare to standard, price, performance.. and ease to run.. I am not clued up on air, intake and out, i gather it sucks straight from the light, to which i attach duct leading out of the cab.. Where do i connect a reverse fan to suck this air.

Also air going into the cab. How do i keep fresh air into my grow cab without just leaving my doors open during flower.. I will have a fan of course which will escape with a carbon filter, but how do i replace this air..

Any helpful tips/pointers +rep.

Any ideas on strains for thus dimensions, i Have 5 Great White Shark seeds which i got in the Dam, there quite hard to get hold of, but not sure if she will be a bit to Smelly been a paty of the white family.

Thanks alot guys.

Welcome to the club Barbi .

Mindmelted knows more about hydro systems, so all your hydro questions will probably be answered by him, Wretched or one of the other hydro growers. I'm a soil grower and would hate to give you really crappy advice on hydro, regardless how basic of a system.

As far as your other questions....

An air cooled 250 is definitely going to be better for heat control hands down. This way you can have a separate ventilation system to control the heat from the light.

A basic ventilation system always has outake at the top (As heat rises), and intake is at the bottom (Cooler air is lower). This ventilation system would be the one you would want to put the carbon filter on.

Both systems should look something like Attached pic 1 (Sorry for the crap picture lol). The carbon filter will be on the basic exhaust not the light exhaust, whether you choose to put the fans inside or outside the cab is your choice, same goes for the carbon filter.

With both of these ventilation systems in your cab you should have no problem controlling heat. The cost can be a little rough.... I always recommend HTGsupply, because they're customer service has always been great and they're products have not failed me yet. You can check out either their ebay store or thier actual website, thier ebay store tends to have some better price options. This should give you a rough estimate on pricing.

As far as making holes, if it's a cupboard that already has a door to it just get yourself a drill and a 4 inch drillsaw, that way you can drill the holes yourself.

T5's are good for veg, but I have seen good results from HPS also. T5's are more ideal because they have more of the Blue spectrum which the plants like during veg, but like I said the HPS isn't too bad itself. If you're not on a budget go ahead and get a T5 if you're on a budget however stick with the HPS.

The dimensions you have are fine for a 250, if you keep your light 5 inches or about 12-13 cm above the canopy you should be fine to grow 3-4, decent sized plants. The carbon filter should take care of any smell, so don't worry too much about that.

Wow that was a long one lol, hope this helps some Barbi if you have any other questions, ask away. Your hydro questions should be answered by someone later.

Doobieus, Many thanks for the response.. Very detailed thanks..

First, whats your basis on growing soil. Ive grown twice before 1 success 1 bad failure trying a haze sativa when i cleary didnt have the knowladge and the patience for her.. Soil i know will taste a hell of alot better, burn brilliantly, But im just worried about Nutrient build up, Not easy to flush.. Bugs... Hydro just seems a bit more plug n go.. And seems that bsed on other peoples thoughts greater yield..

So if i but a air cooled HPS its built into the device i dont attach a sucking fun, or would that be my carbon filter. Ive looked up a few cabs.. And i know i will have a duct attached to the top of the light which will exit the cab, but does my carbon filter also enter these path... Im sure i will figure that much out.. But want to have the in/out airflow on the low down asap...

4 plants hmmm, when i look at the cab, i see a nice heaight but not much side potential if more than 1 plant.. I would love 4 plants and just to focus on the top colas on each of them, aiming for 28gram each plant.. lasting me till my next harvest based on 4.. But im happy with 1 also.. I saw a chap on here, grow journals.. 1 huge pot with soil... and he made some heavy shit fat dank buds make me wanna love him long time,......

i just love the hole growing and crumbling smoking smelling of weed as we all do... and... i cant wait to bust the seeds open.. curing wil lcertainly be the hardest,, They say Patience is a virtue..

Londonseedcentre anyone tried them reliable, any1 got a 99% reliable source.. Any recomendations on Indica strains tried and tested with high resistance and the more obvious qualities, thc and yield and porn value...

Im going to get a 250aircool, so thats me with my P plates.. I may skip the other lights and hot the veg with the HPS, i aint no perfectionist..But will treat my 1 2 3 or 4 babies with proper due care and plenty of attention... rest assured.

thx again mate.

Christ only just saw your attachemnt, very simple but amazingly made alot more sense, amazing how us lads and pictures seem to go so well. thanks i get it now, could still be convinced on the soil use though...

Doobieus said:

LST or any type of training in flowering is a pretty big no no because of the risk of hermie-ing your plant out. The heat depending how high in the 80's we're talking here is going to stunt it and cause buds to grow out spindley and stringy.

Also sexing can take anywhere between 4-9 weeks (From seed) to actually show (Depending on strain and other variables), the further you're into that the better because they're more than likely female.

For example, my Black Dominas are not showing sex and they are at 5 weeks and 1 day. I grew out another Black Dom prior to this grow and it sexed at 4 and a half weeks and was male.

Just wait it out, smoke a until they hit 9 weeks, because that is normally the maximum time before they show.

Hope this helps Burnzy.

damn alright. i'll deff be doin lowryder's after this. can't wait for them =] Thanks for the help though!

I have thought about going hydro plenty of times, but I stick with soil. Soil if done properly will usually taste and look better. Hydro to me is more for yield, don't get me wrong the taste and look do look and taste good, just not as good as a quality soil grow. Depending on the soil brand, you might want to let the soil dry out to prevent any pests from the soil bag and don't over water. Flushing isn't too rough, 2 weeks regular ph'd water when you start to see amber trichomes or an amber hue to your buds. Nutrient build up and flushing can also be done with a product called ClearX, it breaks down salt deposits/nute build up.

The carbon filter would be attached to the basic vent system not the light vent system. The light itself would have the fan on outake pulling the hot air in 1 direction, the gray squares are supposed to represent ducting in that picture lol.

You don't have to grow 4 plants, you could always look into LST or ScroG, you would probably be able to do 4 plants if you did a Sog.

As far as seeds are concerned, Attitude is a good one. Lots of selections to choose from, you're bound to find something to suit your needs.

Oh and by the by, I'm not a lad lol.

Hope this helps some .

If you're thinking of goin' with lowryder go with lowryder #2 or go with a hybrid. Trust me you'll thank me in the end lol.

Yeah waiting it out can be rough, but well worth it. Keep your head up Burnzy, behind every dark cloud is a silver lining.

Also no problem for the help, hope they show soon though .

Hi Iam currently planning/building a grow closet for a 250W HPS.
Dimensions 1.5ft D 2.5ft W 6ft High. Pretty small, about 4 sqft grow area. Do you think this will be ok running air cooled reflector?(6" fan) plus a second 6" extractor fan for passive intake?

A 6 inch fan will be enough for that small of an area, especially if you have one pulling out the heat from the light and the other pulling heat from the grow cab (Depending on the heat in the surrounding area of the grow cab).

Hope this helps some.

thanks a bunch Doob your a big help!!kiss-ass
helping everybody your great
tonight's smoke out goes to you!

Yeah I gave Barbi some info, but I think they wanted more info on hydro. I left that for you and Wretched, because I'm not as familiar to hydro as I am with soil .

Dunno if Barbi still wants that hydro info, but it couldn't hurt .

Thanks for the heads up Doobs.The WB is looking good,had a small issue with the middle cola though.It got burnt some over the weekend.Will have to see how she does with that

And WAY too good of a time

so I went and got some soil and nutes while I have the free time. I picked up

Happy Frog Soil
Humboldt organic grow
prozyme
humboldt roots (organic)

anyone every used these? reviews?

hoping this gets me thru veg, I tested pH on my solution and its a little over 6 but under 6.5 so looks good for now, Im following the feeding schedule on a cautionary basis. Also I wanted to try and put a couple little guys into the 1 1/2 gal pots so I did some and they went alrite, they werent ready tho roots small yet, but I dont think they got too messed up, good practice I gues thtats what bagseed is for.

Ill post some pics at the end of the week hopefully they get some more leaves going!
