Lighting Questions for TaNg and of course all others familiar with HS1

[Vlada]

I am new member her owning 1 HS1 led with 80*80 diffuser. I would appreciate if anybody get time to help me with few things.

Considering stealth grow space of only 53 with 67 cm, height ~170 (or 0.35 square meters) and 2 photoperiod indica dominant plants (L.A. Ultra by Resin Seeds -not big producer, 350g/square meter, stretching very little after changing to 12/12) planing to veg for a month? (or until it takes to cover the whole space using LST or topping) in textile pots, with bio canna nutritiens and bio canna earth, so organic grow:

1. should I use two 10lt text pots or two 15lt? I think two 15lt may be to much.

2. what do you think for how long could I max veg considering pot sizes only? to prevent running out of pot space. both for 10lt and 15 lt?

3. could 60*60 diffuser (so not the one I have now) effectively cover the whole space and what min distance from canopy should be considering the grow space?

4. what is, from your experience, for 60*60 diffuser min distance from canopy regardless of space?

5. would I benefit if instead using one HS1 led light, I use 2 lights for that small space? If so, I understand that 60*60 diffusers are the best for flowering, but two 60*90 diffusers will perfect cover my grow space, so for which option should I go? wouldn't I get more penetration from two 60*60 instead two 60*90 even if not equally covered?

6. is it must first to start in smaller pots and then transplant in bigger final pots? for photoperiod plants starting from seeds.

7. next biggest issue would be correct feeding with bio canna, but unless you have experience with bio canna, I guess it is on me to found out,not to stretch to much this post otherwise I have many questions on feeding.
Cheers to all!

because of the small space i would go for a 10ltr or even smaller i have seen good growth out of 1ltr air pots so it all depends how big you can go

because you have a photo-period strain you can control how big it can grow and you can use techniques like topping or LST to fill out the space you have but remember to have good ventilation the bigger she gets the more humid it gets

i would say from seedling 10-15 days for the first few leaves to come through and then 1 or 2 more weeks veg and then hit it with the 12/12 once again i depends how much space you have

with regards to the HS1 light i don't own one yet so i can help to much with this

with starting the seeds all i ever do is germinate them and then stick them into final growing container you just need to remember to water consistently so the roots can take advantage of the whole pot if you water heavy and leave for a 2 days or 3 roots tend to search for water and stretch to fast not taking advantage of all the growing medium

i am currently doing an organic experiment of my own right now i am not using any bottled liquid fertilizer rather just built a good soil base im using biobizz light mix and ive added - (worm castings, Alaskan Humus, Volcanic Rock Dust, Sea Minerals) and letting the biology in the soil feed the plants all you do is feed the biology with compost tea's there are many good recipes in the organic section on this forum check it out

not sure how much this helps but i tried

Vlada,

I think you would benefit from 60x60 diffuser in that space. One HS1 certainly would be sufficent for 0,32m2 area. Size of your pots depends on your growing style and the strain you would be growing. I see L.A. Ultra is rather strong Indica -hybrid so it most likely stays rather short. Are you planning on using other means and techiques to keep your plant for growing too much vertically? LST from 2nd week on has worked really well for me. I'd advice to rather go with bigger airpot from start to finish and only use one of em. Then work on keeping the plant down low.

If you want to keep your plants down, I'd advice you a following method for distance of your HS1 -unit from the capony. This method has worked well for me with 80x80 diffusers on, so if you are going to use 60x60 you should add 25% more distance to all these values:

- Start up with 40cm distance for a young seedling.

- Let her grow up to 20cm away from the light.

- In early generative period you can let the plant reach maximum of 10cm away from the HS1 -unit. This is extremely close but works to stall the vertical growth. Add extra calsium and magnesium to the feed during this time since the added strain will make your plant require more.

- After approx. 4 to 5 weeks into the generative periods, ease of the light to about 20cm away maximum and keep it there for the rest of the cycle.

If this is a stealth grow, how do you plan on doing the ventilation? 170cm of total height allows for some headspace for heat to rise but you have to vent it out good and allow good air circulation to have the fan leaves moving and triggering the plant to use it's energy the proper way. 2 units in a rather small space with inferior air circulation would lead to overheating that will lead to the units dimming themselves down and hurting your plant(s). Anyway. I wish all the best and good luck. Keep in mind that these are my personal suggestions and other might be in a different opinion. This is just what has worked in my garden and in my grows the best. Each garden is individual setup with multiple different variables so there is no clear cut way of doing things really.

Good luck.

Thanks for replay,

so both of you advice to go with final pot size from begin, for photoperiod plant. It would not be airpots (unfortunately don't have them) but pots made from textile, similar to smart pots. I am still thinking starting with smaller plastic pots and then re-pot in 10lt max 15lt tex pots. Wouldn't in this way roots full more of the mid part of the pot? And, MedGrower, it would definitely be 2 plants, and with LST technique from more less 2nd week as you advice, to create an even canopy.
The grow space is made in unsuspicious cupboard with passive intake and active output through S&P TD 160/100 silent fun + 2 desktop usb funs for air movement in the box, so unnoticeable noise (this is why I call it stealth). In case of 2nd HS1 I could add one more TD 160/100 connected to another filter (for summer time), I could fit in. While one HS1 would be enough, would I benefit from 2nd light? And, as I questioned in first post, should I than go for two 60*60 or 60*90 diffusers for max yield?

MedGrower: "If you want to keep your plants down, I'd advice you a following method for distance of your HS1 -unit from the canopy. This method has worked well for me with 80x80 diffusers on, so if you are going to use 60x60 you should add 25% more distance to all these values:
- Start up with 40cm distance for a young seedling.
- Let her grow up to 20cm away from the light." - thanks for advice! This is almost exactly what I thought too!

Also, wouldn't 4-5 weeks of veg grow be risk with 10lt tex pots? I know that you had bigger airpot in mind, so this is why I ask. Of course I will have in mind that 4-5 weeks in veg could be to much for 2 plants for my space, but just in case it took longer for plants to grow and spread with LST

Finally one silly question, how save is to post here personal grow? Is anything there I need to know? I would love to try to compete with you guys

Thanks again!

"with starting the seeds all i ever do is germinate them and then stick them into final growing container you just need to remember to water consistently so the roots can take advantage of the whole pot if you water heavy and leave for a 2 days or 3 roots tend to search for water and stretch to fast not taking advantage of all the growing medium" - so to water less but often, without leaving earth to dry completely? Wouldn't it slow down the plant's growth?

 

[Knowhowitis]

With regards to watering the idea is to water without run off so for my seedlings I'll water between 200-300ml a day in a 15ltr pot it's not going to make much of a dent
As its roots get bigger and drink more I'll water a little more but still without run off towards the end they can drink easy 3+Ltrs a day

Hay bro a warm welcome to AFN and the GN gang....some great advice from the guys above. If your set up was mine I would grow just 1 plant starting from seed in the 15L pot and vegging for 4 weeks before flipping the lights to 12/12, I would use the 80x80° in veg at a height of 40-30cm then the 60x60° as soon as she buds up at a height of 20-30cm. Try to keep the room between 35-45% RH and 26-28c throughout for the best transperation and therefore growth. Start a diary in here bro and we can help you throughout.

Thanks TaNg. They are out of 60*60 diffusers and strangely, they are not sure if they gonna have them soon, even in one month from now. I just spoke with Crazy Leds few days ago. It seems they have some issue. Do you know something about it?

Don't think there is a problem with them bro just out of stock,the 80x80° works fine in bloom too plus you can have it a bit closer,I would use it at 20cm.
