Jmaninthemidde420started grow question 2 years ago
Can you use a 450 watt white led light to start seedlings? If so what distance should the light be and when should I make it closer? The reason I am asking this is because I don’t like transplanting autos as they are fragile to transplanting from what I’ve looked up

Yeah - you don't want to transplant autos EVER... they just don't like it at all. I generally have my lights about 30" above my seedlings because I grow in a tent but I have friends who have a grow ROOM and they put their lights about 5' above... You just don't want to get them too close because they will easily burn. Putting them up high also encourages stretch. Beyond that, it's a matter of "reading" your grow to see what they need... if they look like they're too tall and spindly, lower the lights... if they look "normal," don't move the lights... if they're stacking up and too bushy/not enough space between nodes, move the light higher... They really WILL tell you what they need/want!
Good luck!

When did the flowering start?The LED panel, after switching (Ts600 Mars Hydro), stayed slightly on even during the dark hours. I managed to fix the issue, but I'm not sure how to count the flowering period. The plant had shown some differentiation, a few pistils, and a bit of stretching. What do you think?

dli 40x40 growbox lamp distance problemhi guys, I have a ts1000 at a distance of 50cm they tell me to lower it to 40cm but the dli would greatly exceed (60 dli photone) the recommended threshold of 40/45. Having a 40x40 growbox, in your opinion, at what distance should I keep the lamp?Plant. Other

Lighting cycle for VEG stage. Is 24x7 OK?Hi,
Should I use the VEG lights 24x7 from the time I plant my seed until it's ready to bloom, or would something like 18 hours on and 6 hours off make more sense? Is there a "best practice" for veg lighting? It has worked for my first 3 grows. VIPARSPECTRA 600W LED

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions

Got a Mars Hydro TS600, will it do alright?My plan is to grow only 1 plant, in a 40x40x120 tent. I know the tent is pretty small but hopefully i can do some training on the plant to grow wide
Will the light do until the end? 100wats, but no light dim possibility. Currently growing seedling at 13 dli at 60 cm

Could anybody please suggest which LED light they would recommend for a 4x4 grow.
Willing to spend around £500 maximum as I really want to invest however most videos on YouTube are marketing their own. Really appreciate your advice.
Many thanks!
