No phen, you do not have to, most of us want to. We know that lights around the 6500k range work best for vegging plants and that lights around 3000k work best for flowering plants. And since we expect to have plants in both stages all of the time, we change the 'room' the plants are in and just use the same lights in the 'room'. VV

Thanks A lot that helped a novice like me! I have so many more questions but that answered probably 90% so thank you!!!! R

Look At Different Lights and Options

I have a question about flowering time that I didnt see in the already asked question list. I would really appreciate if I could get an answer from someone.

I purchased some Brainstorm seeds a couple months ago. They are listed at 7-9weeks of flowering time. When do you start counting the number of weeks its been: the day you switch the light cycle to 12/12, 2 weeks after you switch the lights, when you see the first female flowers or ....... ?? I'm just trying to get a ballpark timeframe in my head. I've had so many people tell me different things. Thank you kindly.

... You would start counting from the time you change the light schedule for planning purposes. You still will want to check your trich's before deciding they are ready to harvest so that is all it is, a ballpark figure. VV

i got one question for all of you... would a indoor grow go bad if a flushed my plants in rain water b.c its been rainin alloooot ad would it be almost the same thing as regular flushin just god is doin it for me =0?

hey. this site has been fantastic, but i cannot find the help i need on this.

uk based, this is our first grow, using a NFT system, like this

http://www.growell.co.uk/p/1538/Hobby-Kit-NFT-250.html

in a grow tent, about 2ft x 2ft. everything seems to be going well enough with the two plants - feminised (i hope) seeds from amsterdam. they are reacting well to light, are bushy enough but getting to about 17inches tall. about to go onto 12/12/ to flower.

one of the plants, an A.M.S Variety, looked a bit odd. from more info on here, looked like it might be nutrient build up.

flushed the sytem and ran it in just ph5.5-6 water for a couple of days.

when removing the tray from the tank, i noticed that the roots have grown so much they have grown off the side of the tray and are now hanging down into the tank, so i assume this is causing the over feeding to this plant.

question - what do i do about it? i assume cutting the roots is a very very bad idea.

help, oh wise ones - i am new and need help!

thanks,

tuff-les.

What is the temperature of your water? If in fact your plant is over fertilized, what is the ppm in your tank? Whatever is was, drop it a little and see if that has any effect?
What you do about those roots is just make sure they don't block the flow of water.
You are going to have issues space issues if you are just starting to flower 17" tall plants in your tent. Your plants will double and possibly triple their size after you start 12/12 light cycle.
If you don't have a journal please start one a send us a link. VV

wow - lots of questions! haven't been paying attention to things like the water temp. not sure about the ppm either. this all seems very technical to me - i was more of a just go with some general guidlines. i know that after speaking to the guy where we bought the hydro kit from, we put in nutes under the recommended amount.

i will have to check into some of these things and get back to you.

one plant looks fine, lemon skunk, while the other A.M.S variety has odd leaves.

this is all growing at a friend of mines (not a pretend 'friend' actually at a friends) so i will chat with him and try and see the things properly tonight.

is it worth starting a journal now? don't seem to have much of the technical knowlegde that most of you have - more of an easy-go-lucky attitude!

anyway, thanks for replying, and i will get back to you.

spoken to my mate.

we have added 1ml of nutrients to every litre of water, about half what the guide said to do. the nute resevoir is about 12litres, there is no risk of the roots blocking the flow of water at the moment.

ppm i assume is parts per million?

i will try and start a journal and post some pics. bit worried about space now, but maybe it won't be a big problem! fingers crossed.

UPDATE - having shown my friend some of the pages on here, we now think it might be light burn. that could be why it is happening to one plant and not the other? anyway - pics etc to follow.

thanks,

Yes tuffles, I do think you should start a journal. One of the reasons is somewhat selfish, I am an old man and I can't remember all of the details of my own grow. By having all of the details in one place, I can check through it and try to find out what is happening when someone says they have a problem.
You and your friend have gotten this far with out a ppm meter using NFT, yep, you need to post a journal. It sounds like if anything it may be nutrient deficiency not nute burn, a picture of the problem might get you an intelligent response, and those would belong in your journal.
Read some NFT journals, I have not used that system, I did see Earl's space shuttle in operation, his plant was over 5' tall.
Welcome to our forum, send me a link to your journal. Please VV
