New Grower How tall should my plants be

[welshboy]

Thank you I will try and take some pics with the lights out and right way around buts it's a dark hole in that tent and auto pots sit in a tray with there food so drip every where when moved. all 5 led''s are now sitting 90 cm or 3 foot above lesson learned there let's hope they stretch I'm used to keeping them short and bushy then switching to 12/12 with photos and leaving them stretch so school boy error there lucky enough the ultimate in there are 3 wks old just the extreme at 5/6 wks would take hit there true potential
