*** Ask Dr. VonDankenstine ***

thanks for the help howard! another question does it matter what airstone i use for more oxygen? i currently use the small one like in the picture and looking to get the air curtains. do you think it's worth it or don't bother.

I just picked up 2 18' air curtins and found I need a bigger air pump. to power them or even one of them. The more air the better. ya I know I'm not howard my name is lisa

Dear Dr
would you aid me by telling me how to produce approximatly 350 clones so that 300 may live.
im interested in lights, pot sizes, and number of mommies.

OK DR ive asked this question in all the diffferent sections and ive had not 1 answer so if you can id apreciate your thoughts ..............

hi all , its not very often i ask for help , but i need some experts advice please .
i recently blew my 250w envirolite bulb , i hooked too much stuff into one power cord and it popped my bulb somehow anyway i went straight on ebay to buy a replacement , but i noticed a bargain hps 250w , that i couldnt resist , ive grown with hps before (a 600w ) in my old place , but couldnt use it in my new place , so i sold it .
anyway i bought this 250 cause i can controll the heat on it, but my problem is it dosent come with a power cord on it , im a builder but i dont do electric and electric scares me as ive had a few jolts on building sites , but i kind of figure im capable of fitting a cord and plug if i know im doing it correctly .
my thoughts were that id fit a 13 amp plug on it and that would be fine , the light has the terminals to wire to so i guess its a easy job , anyhow i happend to notice that the guy was selling a few of these lights and on one of his auctions he says if your fitting a 13 amp plug , you should fuse it down to a 5 amp fuse , does he mean just use a 5 amp fuse in the plug that you attach or does he mean the light (ballest etc ) needs to be fused with a 5amp fuse and then fit a 13 amp plug as planned .
hope this makes sense to you all , i havent recieved the light yet but heres a link to the same light off the same seller , if you dont mind taking a look . thanks all. http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=270317741617


btw i got my light for £14 + £10 for shipping , wich i think is a bargain ?

first off the ballast is wired for euro standards. you have to supply 220v, but here in the states we use 60 hz frequency. your light is wired for 50, honestly i dont know what that will do. as far as the fuse, i think youll need to open it up when you get it and fish for a spot for a 5 amp fuse, cause there is no other place to stick it. connecting it is simple, hot to hot, neutral to neutral, ground to ground.

yeah im in europe uk so i just need to atach a cable to the terminals fitted with a 5 amp fuse ?

The small airstone will work for airing out the water, but you'll need a bigger pump and more of them if you're doing bubbleponics...

If you want to have 350 clones, you'll need 7 clone domes, and probably more than ten mothers... Huge ones.

Try to get all 350 to root...

I explain my cloning process in detail in my journal...



And sorry, I can't help with the uk wiring... But a side note, there is a big difference between regular 250 HPS bulbs, and the ones made for horticulture... All ballasts have a fuse built in.

thanks mr.marks, i flipped through you journal i found a brief section there on how you clone and thats fine.
im more interested in how to make that many.
i have a 400 watt in an adjust a wing reflector. they say i can use an area of 3x4. and thats what im gona do.
how many mommies and how tall do they gots to be to make max clonies
can i put 1 per square foot?

yeah i orderd a new 250 hps bulb seperatley i kind of figured the one supplied is second hand and probally dosent have much life left in it .
think im gonna email the guy whos sellin them , for advice on wiring it up .

Good idea...


And the clones... I could probably snatch 30 clones from each of my mothers, they're pretty damn big though... But I could easily get that many from a 4x4 area of mothers... And that 400 will be perfect for them.

You can clone under regular old shop light 48" fluorescent tubes. You can fit 4 trays under each light, 50 clones per tray, so two lights... Clones hardly need any light, I find the 48" tubes work great.

i have 2 questions if you don't mind u was forced to transport my girls in boxes temp 22 degrees f to a different location and the co2 in the first house was 500 ppm but the new house has a big family living in the house so the ppm is 2500 and they showed some stress(leaves turning black and brittle)i was wondering how long would you let them veg before flower cuz their big!
and i was wondering if this jump in co2 will help or hurt,i think thats what shocked them.thank you!

Hey doc, I started a thread, but no one could give me any answers, so I decided to just ask you. I noticed some powdery mildew on a couple of my plants. few along the edges of my room, and now its starting to make its way in on the ones in the middle. Each plant has about 10-20 leaves with spots, about 10 percent of the plant, if that. Its very light right now, and I feel like I can get a handle on it if I start to fight it now. I am on day 23 of harvest (2nd day of week 4), and I am worried I am going to lose my crop. I have acquired a sulfur burner and I am waiting until my lights go off so I can use it. The reason why is because I also turn off my inline fans when the lights go off, since I use them to duct the lights. The are also hooked up to a carbon filter that exhausts the room, so, I figured I would need to turn off the exhaust while I use the sulfur, so it stays in my room correct? Now, my questions are as follows: where do I hang it, on the edge of the room, in the middle? Do I put a fan behind it, so it will disperse, or will it do that by itself? And how much should I use and for how long, and when should I see results? AND (whew) is there anything else you could recommend?

Your doing the right things by addressing the ASAP----First thing your should do is set the sulphur burner to come on at lights out. Sulphur can easily burn with the lights on---second you want to hang the burner above the canopy as high and far away from direct contact of the plants. Your oscillating fans in the room will disperse the sulphur. The units heat up rather quick so 8 to 14 mins after heat up should be ample unless you have a room over 2000 sf. I would also pick up a bottle of safers sulphur spray and hit all the corners of your room and the areas were you see mold. The mold is probably from high-humidity or poor ventilation with high humidity so you need to either add more ventilation to the room or add a dehumidifier or both. You want your room to stay below 50% humidity at all times. Powdery mildew is bad but bud rot is worse. Heat can also worsen conditions so keep it in check------75 to 78 without co2-----83 to 85 with. If the one Dailey application of the sulphur burner is not taking care of your problem 100% add another application about one hour before lights on. Watch the foliage closely for sulphur burn and decrease the dosage time immediately if present. DO-NOT foliar feed your plants at this time------The sulphur will change the surface PH of the leaves---You can also use the safers sulphur spray on the top of the soil(if your in soil) but I don't recommend the use on the foliage. Hope all this helps----PM me if you have further questions----good luck...

Hey just wanted to say thanks, again man, and I sent you a PM witha few more details about my issue. Your help is greatly appreciated as always...

my stems have some red in them. should i be worried, and what is this from? thanks for your help

Yeah, doc, that reminds me. My stems of my fan leaves have red streaks on them. I always thought this was normal, but someone else said that it is a sign of nute deficiency. It goes right down th emiddl eof the top of the fan leaves stem, from the base of the leaves, down to the stalk or branch it is connected to. Is it really just natural, or does it mean something?

Can be normal on some strains and the very first signs of a nute def. Just keep and eye on it---If it is a nute def at this point increasing your ppm's by 50 may just take care of the problem.

That is normal in a lot of strains---as I said above to mondo---Just keep a eye on it---if they get darker red or purple your may have to increase your ppm's.

Dear Dr or Mr.M

i have little ones vegging from seed right now, they are in coco, being fed a 3 part nute. about 4-6" tall
Up untill now i have had no need to check ph and ppm, i always put less than recomended. just to let you know its on the high side above 6.5, ppm were at 800 i reduced it.
another thing is that it got really hot with the light in there, its only a 150w cfl, but no air circulation and when i put a thermometer in there i realized it was in the high 80's. again up untill now ive had no reason to want to check.
the leaves are yellowing, spotting, curling, drying on the corners. they seem to have stop growing
as of now temps are normal, but what do i do about the feeding, i know i have to get some ph down, other than that?
do i need to flush the coco?
give it vitamin b?

DR. VonDankenstine said:

The correct and only true answer would be ----They could!!!----Until you grow them out you will not be able to know but the chances are very good that they could produce Hermie because of the "self pollinated"---If you are worried about the Hermie's there are 2 things you can do----1. Use Dutch masters reverse at the light switch----2. take the chance that they will not Hermy(watch for male flowers closely. 3. Don't grow those seeds out. Hope this helped to answer your question. As you have probably already found out if you have read most of my threads---I'm not a fan of feminised seeds.

Why not a fan?
