I must have got the 5 stars by mistake your rep means more to methx

No mistake with the stars my friend. You are doing something i've never seen anybody else attempt in many years on the forums. This thread is a very valuable contribution to the world of micro growing. It's even better that you are also sharing your trials and tribulations with the italian community . Glad i've been able to do my small part to assist you in this journey.

In that case a better start show some results, this run is what it is , at least i made some seeds and i am making some changes untill the second run, is all a learning process anyway, i have to fill those nets. I am glad you keep a eye on me

how much weight you think you might get?
they look more sexy every time you have a pic update!
i have ? , i wanted to get a tent its 32wx32Lx63h im planing to get a 150 hps for flowering & use flouresents for the seedling stage & veg stage,im going to get a exhaust fan with a carbon filter attached to it, i want negative pressure so no smell gets out the tent cuz smell is a big problem for me anyways do you think this is enough space to have a vertical grow i like the vertical idea cuz i really dont want to waist money on a hood?
what do you think?

 

[Mister_D]

420stoner - To answer your question, yes vert is definitely possible. You will however need to employ some form of training to keep the plants from getting to close to the bulb. Take a page from sgapetti and/or marlo's WOW thread here in the vert section. Your proposed room is ~34 cuft so make sure you get an exhaust fan rated at min 100 cfm to account for losses through the carbon filter and still allow air to be exchanged twice a minute. I would also recomend getting a size bigger than recommended carbon filter if smell is a big concern. This doesn't mean you have to up the size of your fan.

Confirming pollination on the sam the skunkman is been 34 days
from pollination and starting to show the formation of the seeds while the rest of the seeds are almost ready on the others plants.
I have to decide a sexing method for the second run, and after reading this 3D https://www.icmag.com/ic/showthread.php?t=229359
I may use it ( i am testing rigth now in a pc case micro grow )the idea is to start 12/12 from seed, 1 week in beer cups and then transplant in final container . When sexed i will switch back to 18/6 or 24/0 and veg till half of the nets are full or something like that.

Peace S

Lookin nice and healthy!
I hope I didn't miss it somewhere earlier in the thread, but next round will you be vegging longer and filling in the screens more?
I bet it's smellin' pretty good over there, keep it up!

thanks for the answer Mister D!
to get a negative pressure you need a exhaust fan that pulls more air that the intake am i right?
if im right can i have a pc fan for my intake or do i need a bigger fan to bring fresh air in ?

thx for stopping by JustDoIt, i will be vegging longer . I have to find a new method for sexing my plants and i am testing 2 different ways as we speak : by preflower in veg and 12/12 from seed until first female signs shows and then back to veg. I will increase soil quantity as well. My biggest issue is roots development and for this reason i am considering vegging and flowering in final container. You have done a great job on your vertical , i will use it for inspiration for sure

You are correct about achieving negative pressure. Intake fans aren't really necessary when using a large enough exhaust. Many ways to skin a mule as DHF is always saying. If you choose to use an active intake get a fan rated at ~ 1/2-3/4 the cfm of your exhaust. However in you space I would just use a 100 cfm exhaust and make sure your intake holes are double the area of you exhaust hole/fan (i.e if you are using a 4inch exhaust you would want a 6inch intake hole or two 4inch intake holes or 4 2inch holes) Whatever combination works for your design and gets you double the surface area of you exhaust. These general rules can be applied to any size room/cab. PC fans aren't designed to deal with much static pressure, so they aren't really a good option for anything other than tiny pc case sized grow. Even then there are better options. If you desire to use one i'd count on only getting about 50% of it's rated cfm.

Sgapetti - Looking good bro. I'm already looking forward to your next run with a longer veg.

[Mister_D]

Did your cab get really hot? or are those leaves burnt from the uvb bulb?

 

[sgapetti]

hello D, had a problem with my exhaust fan last week ( replaced ) when the soil was low on water ( before watering ) resulting in some dry leaves for the ones closest to the lamps.

they still looking good man!

Took a hit from your exhaust going out, but all in all things are looking very nice for you my friend. When do you get to begin enjoying your spoils?

Wsup D, not happy about this run, hopefully i get some good seed at least , anyway wonderfull smells even from the sam the skunkman freebie and sticky weed, but not much of it, i keep trying

Chopped all but the 2 Sam the skunkman freebies. Not much to say about this run , my plants are getting smaller. I am planning a few changes till the second run.

 

[Mister_D]

Can be hard to compare one run to another when growing from seed. However there are always improvments to be made no matter who you are. Just remember any harvest is a successfull one. Always take what you have learned good and bad to apply and better the next round. I'm here if you need any suggestions or help bro. I'd forget about those uvb/uva bulbs, like I told you before nothing but decreased yields from what i've seen (your grow seems to have folllowed suit). IME healthier plants produce more resin. Uva/uvb may or may not help a plant produce more resin, it's all subjective until someone has lab tests done on clones grown with and without in the same enviroment. Even then spectrum must be considered, as this has effects on the chemical reactions that cause a plant to grow/produce cannbinoids. Especially in a setup like yours where light is already at a premium it seems even more of a waste of time/energy. I encourage you to experiment, but do your research first and put your efforts into things that have proven fruitful for others. Being you seem to need your plants to stretch a bit more greater amounts of veg time and red lighting is your best bet. Perhaps go all red lighting until stretch is complete then a 2 to 1 ratio of red to blue for the rest of flower for quality increase. Another thing to consider is setting up blumats for watering. I believe i've touched on the importance of watering cycles for building bigger root systems? if not let me know and i'll elaborate. It's all the little things that add up to total enviromental control and top yield/quality. We'll get you there no worries bro .

 

[sgapetti]

thk for stopping by my friend , I am analyzing why , i can only do it by comparing the last 2 grows.
The uvb lamp and his spectrum by herself can not be the cause , but has helped in stunning the plant in the beginning, i will not use it in the second run.

This will change in the second run :

The lamps spectrum is not been optimal as i have been using 4000k and wasting enrgy, switching to 6400k now.

The small containers for veg are going out, they work very well in sexing from 12/12 for sog,but i need to veg longer now . I will germinate in beer cups and transplant directly in final container after 1 week.In this ways the roots have the nutriments directly from the second week and the space to grow. Changing container size as well, more dirt more roots, bigger plants.

The soil is changing as well, partly. I am doing some test right now on some seedling in a pc case.

The sexing of the plants is the issue for me. I am testing sexing from 12/12 from seed and switch back to 24/0 after the first sign
of flowering , after reading this 3D https://www.icmag.com/ic/showthread.php?t=229359
Both tom hill and chimera left positive comments about this method, will soon find out and will document this as well.

If i want to grow vertical i have to think different . I need my plants to stretch and feel the nets , longer veg and at least 2 toppings, and lesser plants,
all this will be possible after sexing the plants.

I am considering playing with spectrum for veg and flower, those c99bx1 will not stretch much when topped, more red in veg is a good option,and less leaves, i am testing this as well.

The reasons why i am changing the soil is because i have done some water absorption test and find out is nearly impossible for the veg soil to get moist evenly risulting in hard, compact soil and lots of dry spots .

Germination for the second fun will start on the 18, if seeds are ready, 5 days before the new moon as usual.

That said your support means a lot buddy, thank you, i have to try
harder and get it right

 

[Mister_D]

Couple thoughts for you to ponder.....

1. if you swapped out your cfl lamp for an incandescent light bulb would you expect that not to effect growth to a noticable degree? My point with this example is uva/b bulbs generally produce very little growth spectrum useable light (400-700nm), same with a incandescent bulb. So growth/yield potential is greatly reduced in both cases. Because you are already working with such low light levels, taking anything away is going to cost you in the yield department.

2. 4000k is likely not an efficent bulb for growing. As I explained before kalvin ratings are somewhat worthless, but can be used to get a general idea of the spectrum a lamp produces. That said 6500K is going to give you short squat plants. You can compensate by vegging longer to achieve the desired size, or veg with say 2700K bulbs which will give you taller more branched plants with less leaf faster. IMO the better route to take for your situation is the 2700K. Whichever works best for you to keep your jars filled.

3. I would recommend you stick with the 2700K at least through stretch to help fill the screens for max yields. Then if you desire to experiment toss a 6500K bulb in until finish to help develop smells and taste.

4. I find through personal experience if using 16oz beer cups seeds are good for about two weeks before transplant. They seem to do best if allowed to become close to root bound before transplanting into a bigger pot (check my first thread for a pic of roots ready for transplant). Once almost root bound and transplanted the roots seem to explode into the bigger container. This results in a good growth spurt. This will also save you room and media while determining sex of the seeds.

5. Curious what your new soil mix will consist of?

6. Never tried 12/12 from seed, but I highly respect tom and chimera. Both are extremely knowledgable and have taught me tons over the years. Thanks for the link to the thread also. I have been under the impression that sex could be influenced by enviromental factors for some years now, according to chimera this is not the case. If he said it, i'm confident he has the science knowledge to back it up. Learn something new everyday.

7. Vertical does take a different approach to master, but you've got the right idea. There are plants with better structure naturally for growing vertical (mainly satvia and satvia heavy hybrids), but any plant can be adapted with topping and/or adjusted veg times.

8. Definitely need to get your soil sorted out. Dry spots and uneven wicking properties create hot spots and ph flucuations that will effect plant health and final yield/quality.

Keep reading and experimenting my friend, rome wasn't built in a day. Continue tumbling down the rabbit hole, and rewards will find you. I'll do my best to point you in the right direction . Looking forward to your next round.
