first indoor grow. mandala seeds Hasberry

[ezahelprup]

hi guys, as title says, this is the first indoor grow for me. i ve already grow outdoor, but i feel lost with artificial lights. so, i popped 7 regular seeds from a pack of 10 of Hasberry from Mandala seeds, germinated in rockwool, i m gonna grow in soil, in a small grow room ( 60cm x 60 cm x 160cm-0.34m2) with a 150 w agrolite HPS lamp(20,000 lumen). this all don't concern my actual problem. what i need to know now, is, when do i have to move my seedlings from the nursery to the growroom for the vegetative phase? i mean, i m already giving my newborns 18 hrs of coolwhite light, about 2,300 lumen, when is good to move them to the brighter place preventing them to be burn? i ll post pics of the 2 seedlings ( other seeds are on the way), so u can also tell me if they look good or not ( giving them distilled water and canna rhizotonic ph 6/6,5. temperature stay between 20 to 25 c°,humidity never goes under 55%)

you can have seedlings under HPS from day 1 they wont fry if your ventilation is right.

ok, so what should i do, quit the cool white light and move all seeds and seedlings to the main growroom? this will be a 18,000 lumen more than now. and, my ventilation it s great, no problems with it. Just, my growshop mate, told me to not stress plants with high intensity light, he told me : would you take a newborn to the beach at 12 oclock without sunscreen? same for seedlings. that s what he told me. so he told me to start my plants the way i m doing now. what do you guys think ???

 

[grod31]

the more light the better . babies are born in the ocean at the beach at w/e time of the day all the time.
i would use all the light have all the time. people start under 1000HPS don't think a 100 watt will kill your plants. just make sure the spacing and ventilation is right

I'm growing mine(also first grow-ever) under a 78W Neutral white (4000K) LED lamp(waiting for 3×125W 6400K and 3× 125W 2700K CFLs), about 20cm from the plant, since 12.1., and I've had no problems. It's lit pretty much all the time.

Like so

Sorry for the double post, adobe's crashing or something so I pressed twice ''submit'' and this is what happened...I'll try to post the image again..

Be careful about taking your babies from low to high intensity light. The transition should be gentle so as not to burn the plants. Place them a good distance from the higher wattage lamp to begin with and move closer as they become stronger.

Take them for an hour at a time the first few days to sun tan under your HPS. Increase exposure until only under HPS. Say over 3-5 days.

 

[fungzyme]

One of the important things when moving to a high intensity light is to have your seedlings planted in something large enough so the increase in light/heat/airflow won't dry them out too fast. Maybe you know this already, but there's no way I'd set those little rockwool cubes in there. IMO transplant them into small pots and give them a couple days to send roots down into the soil (but don't overwater - make the roots look for water at first), then they should take off under the HPS.

thx all guys, i ll follow your avices so actually, the most vigorous seedling has its root out the rockwool on the base, so i put it in a larger container. so, once the root set, should i put her under the hps?

 

[Blue Socks]

Be careful vegging regular seeds under only HPS, the yellow/red spectrum of HPS light has been shown to increase your chances of your seedlings becoming male instead of female. To optimize your chances of getting a female it's been suggested to veg under the blue wavelengths that you get from MH or daylight CFL bulbs. Vegging under HPS will not always get you males but it increases the chances. Thought you should know that as a new grower it's something to consider.

Good luck man keep us posted!

hi blue socks, i have an agro hps, i m a newbie so i don t really know anything, but, shouldn t agro cover all the light spectrum? well i m sure that if there was blue, the light would look a bit purple, while it is super deep orange/yellow. well my target is to have a max of 4 females, i germed 7 seeds, wish at least 3 girls comes out. well i ll keep on posting news, i still love outdoor more than indoor, for a lot of reasons, wish that this grow will prove me i m wrong

Wait till your plants have 3 or 4 alternating sets of leaves before you put them under something other than your fluorescent light.

 

[ezahelprup]

so, today update, the 2 seedlings started growing well and healthy, one wannabe seedling, died, and, all the other, keeps on hiding undersoil.....even if they all germinated...., 2 on 7 it s really bad, maybe my fault. do you think i should start the other 3 seeds i have or i should wait a bit longer?

 

[socialist]

If you do start them don't put them under your HPS. It is not the right spectrum and it is very intense.

 

[ezahelprup]

Ok, all the hiding seeds are oficially dead. Mmmm. The other 2 are doing good , one is super healthy with wide huge indica leaves growing really fast, the other one is way slower and smaller. I m quite disappointed. 2 on 7 and just 1 doing good.:|

Keep trying dude, practice makes perfect. When I used rockwool seed starter blocks I transplant asap. As soon as I see root at the cube bottom. The 2 easiest ways to kill seedlings is under watering and over watering. Do not allow them to dry out, keep the cubes moist not soaked. If they come up and look fine then fall over looking like the stem was pinched at the seedlings base they're damping off. These are the 3 main things to worry about with seedlings.

ezahelprup,
I’ve had seed that took two weeks to sprout and longer. Keep those ones that you’ve given up on, if they’re kept warm and moist you might me surprised. Forkup’s right about water, I know you’re probably checking every 5 minutes (if you are like me when I started) but try to relax and just keep them lightly moist and warm.

 

[ezahelprup]

yeah adze i m like you when u started i check for it every second. but actually a long time like 3 weeks passed by, i m giving up, sure if they decide to show, they ll be welcome actually the other 2 are doing fine, the bigger one is growing so fast and good ! maybe, i failed with the rockwool, i mean i never used rockwool, i always started seeds in soil, just someone guessed me to use it and i did as i m a newbie. but u re here for that , so thx guys
